Thoughts caused by 10 aircraft debate
From time to time
First, watching 10 in the background of aviation technology
The luck in the 1980s is the only large jet transporter in my country, and its advent is better than the world.
The emergence of type jet is more than 20 years, but the development technology has greatly shortened my country's advanced countries.
The gap between home. 10 test flights to many important cities in east, west, south, north, north, including 7 flights
Arrived in Tibet, Lhasa, did not have any technical failure, proved to be excellent in performance and achieve design requirements. 1
In the 985, 10 was interrupted by "lack of funding support". 5 years after the bay war proves this
Big voyage, large carrier air platforms have an irreplaceable key role in modern war.
In the 20 years after running 10 shelves, my country's aviation industry has cooperated with foreign countries and did not continue to engage in themselves.
There is a model of independent intellectual property, and the consequences are the development and production sector of my country 's re-exiting the jet transporter.
It is half a century that is lagging behind Europe and America injured in Europe and America.
Within half a century in the war, large jet aircraft became a front-edge position of aviation development. In addition to in military
In addition to important purposes, in aviation transport, the mainstream role is also as mainfall, the world enters the "jet era".
The "Earth Village" has appeared, and the process of so-called economic globalization has accelerated. Large jet in politics,
Economic, military, social and science and technology, all aspects of industrial production are a heavy enamel, where is it?
Which of the horizon is tilted in.
Next year (2003) is a 100th anniversary of the birth of world aviation technology. Aviation is a hundred years of history, the biggest
Historical leap is a jet technology that appears 50 years ago. There are two obvious effects in jet technology, one is to fly
The machine "high speed", the second is to "largeize" the aircraft. Jeldiation makes aerial history for half a century
The competition has reached a saturation. The maximum speed of the second half of the military combat aircraft is generally stable in "hot barrier"
Previously, the 16th speed of the sound speed was 2 times. The speed of transportation aircraft is stable before the "Physlis", that is, the so-called
0. 75 to 0. 85 times the sound of the "Gaoyi Sound" area. Unlike the "high speed" trend, the plane
"Large-scale" not only does not have a stagnation trend, but it has become the main direction of aviation technology development. history
In the 21st century, the "large-scale" trend is still prosperous.
After the aviation cause enters the jet era, there have been two development models in foreign countries. A model appeared earlier,
It is characterized by a smaller model, gradually increases on the basis of the original model. Early English
The "Huixing" of the country, the "Figure 104" of the Soviet Union, France's "fast sail" is a representative of this model.
These models have been eliminated. It has proved that gradually increased gradual development strategies from small models.
Can give full play to the advantages of jet technology, can not receive the technical effects and economic effects, so it is not spray
The correct development model of the gas plane.
Another mode is based on jumping technology, and uses a jumping method to give full play to spray
The grade of the gas can be jumped, jumped to the other side of the large carrier model, and created a new technical platform. US Boeing is
This representative of this development model. Boeing selected the support of strong military needs, the first
A jet transport model was 880 by the military, and then it was changed to a civil model, sold more than 1,000, gaining great success. In this case, Europe also gave up with "Huixing", "fast sail",
"Trident", ", VC-10", etc., gradually increased development model, hiring, jumping to "A-3
The large load of 00 "has also been successful. The" jet era "world aviation industry is not
Through the "Du" "" Dai "realization from small to large continuous, it is jumped to the other side. Be with a larger
After the model is standing in the jet transportation field, it will go back to engage in small models, in order to be small, from big to small,
It is relatively easy to use the research and development of the picker. Boeing and empty customers do this.
Work 10 aiming at the two fields of military and civilians have a large large load model, with the Chinese own strength,
Fully draw international advanced technology, a big struggle, so that our country leaps large jet transport
the other side. Yun 10 is not added to the model of the model of the model of my country's modeling, but fills large transportation.
The strategic blank snow of the launcher is delivered. 20 years of experience in international cooperation, large-scale transportation aircraft system
The technology is unable to rely on international "friendly", and I can't buy money.
How to evaluate how to evaluate the results? The advent of the transportation 10 is still a bad thing to our country, over the years.
There have been two distinct views in China.
Second, improve the model development capability of the aircraft model is the fundamental way of my country's aviation industry development
In the past 20 years, the discussion around the lucky 10 is boiling, and the people say that Until the 20th century, emerging
There have also been a year of debate on the Internet. Accounting the opinions of Yun 10 mainly from my country's aviation industry
internal.
Yun 10 such a force is achieved by China's own strength to improve China's economic military science and technology
The technological innovation of major value is climbing, but it has caused such a large scale in his country.
Siege, there are fewer history in China in my country, and it is rare in the world. Even the tragedy of "Associate" crashed
There is no attack in the United Kingdom and France.
Talk here to the differences in scientific thinking. Critics often use detail issues to negate the transport 10 in the overall
Achievements at hierarchies.
First, the weight efficiency problem of transportation 10.
Some people publish an article say that 10 structures are overweight, so they cannot be used. In fact, the jet aircraft is
With its large carrier, long range of airbuting technology, the structural efficiency of the propeller airplane cannot achieve, thus
Become the main body of air transport. my country's other "transport" fonts, no matter how improved
10 Flight mission, the reason is that these models are propelled with propeller technology, while the spray
Gas technology has reached a higher technical level. To the weight, other functions, propelled propeller aircraft, each public
The load of the empty machine is 3 times the weight of the jet 10.
Yun 10 reaches 100. 2% of the design load in the structural strength damage test, the overall strength margin
Only 0. 2%, this is an unprecedented precision in my country's aircraft manufacturing industry. If there are more than 10
Material, it is not in the main commitment. Any aircraft did not reach 100% "equal intensity", and the damage test is destroyed, not a whole machine to be fragmented.
In weight efficiency, transport 10 has completed the large task of jump jet transport steps. Inadvertent
The structure of the part can also be gradually alleviated by improving materials and processes. this is
The process of unlimited approximation "equal intensity" theoretical limit is also a process of excavating potential for details.
All scientific tests and test fly proof have proved that the transportation 10 has achieved design requirements, and it is not certain critics.
The "not the original task is overweight".
Way 10 has taken into consideration in the design: that is, the remote flight of the international route and in China
Come and long distance transportation. Strength calculation is from the hundreds of configurations of two configurations, choose the most serious feelings
The condition is as design, and finally the actual loading passes the test. Dadden domestic routes have been included
Within the passage of the transportation 10, there is only a full load of journalists, with the biggest take-away, safe
Flying over the longest route from Shanghai, from Shanghai to the successful flight of Urumqi. The maximum takeoff weight of transportation 10
110 tons, simple and only 30 tons or 60 tons of my country's other "transport" fonts have no weight.
What is the meaning, because other planes cannot complete the flying task of the transportation `10. It is necessary to see a single seat.
The fuel consumption rate of the unit mileage. This fuel consumption rate of transport 10 is more than the "trident" used in domestic routes.
"Ir 62" is low, only higher than the original imported Boeing 707, but is in the same level as the latter. slightly
Improvements to increase the number of guests, and transport 10 can reach the fuel consumption rate of Boeing 707.
Second, regarding the operation of 10 technology.
Some people say that the transportation 10 is 50 or 60 years, it has been out of time, no value. but
It is the technical basis of the imitation of the transportation 7 is the "Folk-27" of the Netherlands before the Jet Age. This is another
Obvious double standard. In fact, the company's B-52 bomber has been introduced for more than half a century, in the new
Century is still the main force of the US strategic air force. "Boeing 737" and "Boeing 747" have exceeded
After 30 years, the United States also plans to sell it for 40 years. It can be seen that a model of vitality is not absolutely dependent.
The morning and night appeared.
There is indeed a "jet era" generation of generation of "jet era" between the propeller aircraft and jet aircraft. But a large
In terms of the technology of jet aircraft itself, in the last 20 years of the 20th century, pneumatic and its structure did not
Promotional innovation, advancement of aviation technology mainly occurs in terms of electronic instruments, engines. "
10 "The general configuration that has been jumped into the jet, and its overall configuration to the new century is still the main body of the world.
structure. We can make this, constantly learn and use new technologies, and constantly update improvements.
Third, about the transport 10 beyond national strength
Some people say that 10 "Beyond the Comprehensive Guo". If this refers to my country's scientific research capacity, then
The fact that the transportation of 10, it has been proven that my country has research strength to develop large aircraft. If the development of transport exceeds our financial resources in our country, then in 1981 by Air Sciences, Chinese Academy of Sciences
Mr. Zhonghua leads the national expert demonstration, requiring 30 million yuan in RMB to complete the lucky
0 test, but finally did not get this money, transport 10 tests were forced to stop. Area 3000
Is there a capital of the capital "transcend comprehensive national strength?"
Later, my country's aviation industry was in the process of cooperating with foreign countries, spent 2 foreign aircraft.
Technical introduction and technical transformation cost of 40 aircraft, the ratio of harvest and expectations is 1/20. my country
The aviation industry also takes 100 billion yuan, requiring foreign lead to develop the "AE-100" plane. people
Said to the country that can provide jet medium-sized passenger aircraft to the country at the end of the 20th century, providing our trunk line
Authentic, and create conditions for developing a larger passenger plane. This is the famous "three steps". But to the century
At the end, this plan is fully emptied. Setting up China, my country's aviation industry pays in 100 billion
Nome meter, no one says it is "transcending comprehensive national strength." Complete the 10 trials of our own research
30 million yuan, although only a few percent of the "three-step plan" funds, it is "transcendence"
"Do you really have a naked double standard?
Fourth, the imitation is still developed? Two technical routes of my country's aviation industry
Why do you appear to talk about the shape of the shape of various monologies? One of the important reasons,
It is because Yun 10 is China's "developing" rather than imitation large aircraft.
In my country's existing three transport aircraft (Yun 7, Yun 8 and Yun 10), only 10 is me
The country mobilizes the national scientific and technical force, "I am the master", independently develop success, the other two are from me
The industrial sector of the country plays production. Opponents are obviously realistic about the "development" airplane and "imitation" aircraft
Double standard.
For example, the grade of the transportation 7 imitation is the 5th batch of "An-24". When the imitation is completed, the former Soviet Union
It has sold 75 batchs to China. Yun 7 missed the improvement of 70 batches, it can be said that
Afterwards. But this does not prevent people to improve and reform in this 5th batch. After 7
Military, one 100, -200 type, has been changed for more than 20 years, to today's "new boat 60"
Modification, the technical foundation is still the first "An - 24" 5th batch. But the goal is 10, but uses another
The judgment criteria, said that it was designed as a special plane, so military and civilian use were inappropriate. Self-study
The aircraft must be adapted to the details requirements of various uses, otherwise the project should be suspended. The first large-scale air load platform in the United States is the first to be used in the Air Force Crease "KC-1"
35 ", then change to the passenger plane Boeing 707. Even in the United States in developed countries, once there is a kind of
The large-scale air load platform must also fully explore its strategic potential, which has developed a variety of pre-warmers "E 3".
Military special aircraft, has been used as the "Air Force No. 1", etc. as the presidential special plane for more than 20 years.
Platform, multi-models "approach, cover military and civilian use range. my country is a
The country has limited financial resources, why is it in the model plan, it is necessary to specifically design a special flight
Special machine, you must re-engage in a special model, and you can do it again in the military?
People use double standards when judgeting my country's transportation type, fundamental reasons lies in my country's flight
Some leaders in the air industry put "imitation, improved, modified" as the road to China's aviation industry.
Advocate, advocating "imitation" and oppose "development".
From the perspective of social needs, scientific research and development and the three of industrial production, the birth of Yun 10 is the society
It needs to be traged, driving industrial production capacity by scientific research development. This is the self-cultivation of social productivity.
Order. Master the intellectual property rights of the aircraft model, use science and technology to improve the development capabilities of independent models,
Raise the role of my country's aviation industry. The traditional "imitation" system is dominated by industrial production.
Turning science and technology to industrial production of the attachment, the order is reversed. But the imitation of the disclator is used to this
Upside down order. When the work is 10 projects, they "don't act", even from the opposite direction.
force. For 20 years, my country's aviation industry development plans to take 10 go to 10, never shipment 10, no matter
China is equipped with an American aircraft, or is led by foreign countries to design AE100, which is the power of China's research and development.
Placed in the place of excuse or attach. However, these plans have no success.
The world airlines don't cherish and cultivate your own aircraft models. It's hard to imagine in the 21st century, one
The country mainly produces foreign aircraft to make the aviation industry truly take off, standing in the forest of the world aviation
Third, the development of aviation technology should take the road to reform and opening up
Due to the long-term imitation supremacy, my country's aviation industry is more familiar with the Susk system. Yun 10 is used
It is developed in the way in the world. From design specifications, design concepts, design methods,
Until the design of the main standard parts breaks the old frame, many of which fills the aviation workers in my country.
Blank in the industry. Transition 10 to the world's advanced technology system, bring large area of aviation science and technology
Receipt.
However, this institutional change has become the mouth of people who are accustomed to the attack of the "Soviet" model.
Really: "Anglo System", as if the Soviet technology is the national quintessence of Russia, is the sacred sacred. Don't know Su
The United Airplane is also technologies from the West, such as the Netherlands. Yun 10 is my country's experts to learn from the World Aviation
Advanced technology comes, Bo Minhang, integrates through China's own aircraft model, which is independently designed.
Many advanced design ideas and techniques are worthy of praise.
For example, transport 10 adopts the saddle forming technique of the Gaoya sound machine wing, than later Russia, Wu
Krand realized that this superior technology was about 20 years. Yun 10 is the first aircraft designed according to the "Air Shuttle Standard" in the world, and my country's long-term use is an old Soviet Union in 1953.
Van, therefore, for a long time, transport 10 is in technology in isolation.
Last year, an anonymous critics claimed to be a 7 pilot said: "I dare to fly the screw paddle.
Machine, but I didn't dare to fly the jet 10, because the cockpit of the lucky 10 did not have infrared lighting, so "Yun
10 The horse is the gospel of China Airlines. "This kind of saying is a violation of common sense, it is well known that the infrared rays are not
Visible, any airplane is not infrared lighting. my country's passenger cabin instruments used in China
Fluorescent illumination or red light illumination. Yun 10 does not use these two devices, but adopts "" "
Lightguide lighting ", this is a general method of world-wide jet aircraft.
my country's aviation industry puts 10, do not abandon its own model development, a heart thought of with Western countries
The cooperation project of the family has repeatedly claimed that "Gandang Primary School, I am willing to learn from the old age, respectfully." but
This kind of humility is not the respect of the other party, but the other party has inch, and the festival is, ask us.
High "Technology Transfer Fees". my country has paid a high "technical transfer fee" in the 1980s.
Such as the preliminary concept of the floor and hatch of the jet transporter, is listed as a god by my country's aviation industry.
The focus of cooperation between the outside party, stunned: "It's really not simple!" But the size and pressure resistance is much bigger than this.
The hatch and floor have been successfully manufactured in Yun 10 years ago. Transportation 10 full machine development
In the technique, the hatch and floor are just a small part. The results of 10 years of research in 10 years
After 20 years, I have a wide range of harvests, much more, and much more important. It turns out that it is developed
The old and old-fashioned exploration climbs, thanks to cooperate, respectful audience, more substantially
Promoting the development of my country's aviation industry. Of course, the self-developing does not prevent us to learn foreign advanced technology.
This is self-evident.
In the history of my country's aviation industry, the transportation 10 design team is the most widely studied, the depth is the largest.
A team of teams. The national jet transporter information collected by this team, the use of the aircraft design computer soft
(Including the computing procedures for the United Nations International Civil Aviation Organization), all countries in the world (hundred hundred
Ten thousand words) is unprecedented. The trial system of the transportation is the technical foundation for the original narrow closed technology in my country.
One of the fundamental "reform" is open to the world to open the world, drawing out foreign advanced technology
It is the milestone of my country's transportation aircraft industry from "imitation production" to "independent development" transformation.
The obstruction and opposition of this reform and opening up to my country's aviation industry development, cannot be considered as representative
The direction of progress will not be considered as the direction representing the development of science and technology and productivity.
Fourth, "Since it is not completed, it should not be completed" is not a reason.
There is an opposition to discuss, saying that the "Air Authority" is not obtained, and the development has not really ended.
This should be abandoned.
Because of the interrupted support, all the test work of the aircraft is not finalized. Mainly, the fatigue test of the structure has not been made; second, my country has not yet established
The valerization of the valeries of the civilian aircraft, so there is no route to the flight. Fatigue
The purpose of the test is mainly to develop a maintenance plan in long-term use, and the airworthiness is the airworthiness.
task. The transport 10 aircraft itself is the design reference based on the airline standard. Of course, in the air
There may be some details of the aircraft in the test flight, which is called "massage" in the air justal.
Massage can make human blood, but not to treat diseases. The aircraft is also like this. There is no large spray in the world.
The gas transporter discovered a large problem in the air transport and declared an example of design failure.
Therefore, all countries around the world have used the new aircraft's launch assembly plant as a milestone. The plane entered
Test flight. The first flight of the plane, the landing of the aircraft is the plane of the aircraft is also the entire trial process of the plane.
The critical part of the circle. 10 perfectly completed the first flight, and further tried to my country
Many representative cities. This marks the success of 10 trial works to achieve fundamental success. People ignore
The specific historical conditions of the time, use "no vacancy certificate", seeking full blame, as negative transport 10 aircraft
Typeful, it is not reasonable. Because the transportation 10 is not "can't get the airworthy certificate" due to technical defects.
It doesn't have access to objective conditions.
In fact, transport 10 is my country's largest jet transporter in China, and it is an enterprise.
Exam, but there is no graduation procedure, get the plane of Graduation diploma. The President of Boeing also passed up
"You graduated, we are just a few years later." It should be noted that some of the aviation industry
Shipping 10 did not get a graduation diploma, and thus advocated the people who were discarded, they tried to advocate the model number of the horse.
There is no entry in the development stage. It's really farther than the truth than Ignorance. According to their
Logic, all the models of all new horses should be abolished, because these aircraft have no vacancy certificate in advance.
V. Yun 10 is the basic platform that my country has developed large aircraft.
There is also an anti-discussion, the model of the transportation 10 has been destroyed, and the transportation 10 needs to re-process
Preparing and producing preparing for work, it is better to redesign a plane. According to the logic of these people, it seems to develop one
The technical scale of the rack 10, the main work is the process, production preparation, not the study
Inspection. This discussion is not worth it. In the point of view of the cost, it is a large-scale airplane that is transported 10.
In the development work, the cost of process equipment accounts for only 28% of the development cost of the whole machine, and 28% is overthrown.
72%, made a mistake due to small loss. From the perspective of technical content, the process equipment is used in conventional
Technology is that my country has been mastered, and many factories in my country can bear their production tasks. Aircraft development technology
It is a core technology that includes a lot of high-tech, many of which need to be able to master through the battle.
During the development of the transportation, since the Chinese Academy of Sciences, the Aerospace Services, Air Force, National Defense Research Institute,
All aviation universities, various aircraft design departments and factories, and other relevant units, all of our country
The development or imitation team of models (including fighters, bomber, transport planes, water aircraft, helicopters and drones and other models) is exhausted, and participating in the development team of Yun 10. Yun 10 development team is one
This team draws all the flying in our country with large jet aircraft as the main product object.
Development experience of model models.
At all stages of the development, dozens of national technical conferences have been held, many scientists, subject bands
The header, senior professor and technical experts participate in the discussion of various issues in development, major topical organization
The team is conducting technical research. The successful development of the transportation 10, after 15 years of researchers in my country
Ru bitter, vigorously coincide, the battle guard, strict argument, my country has uncomfortable intellectual property rights. Shipping 1
0 Among the scientific staff of the engineering project, there are many scientific staff in my country.
Teethers and leaders. In the 20 years of transportation 10 suspension, these comrades have already lectured
Regret to leave the people. Their knowledge and talents, their vision and cardiagy, have not experienced pioneering struggle
The person is very difficult for a moment. Yun 10 is the crystallization of a few generations of aviation people in my country, which is my country Science and Technology.
The results of joint struggle between the boundaries and the industry are the valuable wealth of the Chinese people.
The 10 model is a comprehensive engineering result of multidisciplinary high-tech crossover. If you are in this fruit base
On the basis of the prematurity, continue to the development, the success rate is much larger, and it can make my country's large aircraft production
The industry is successfully transitioned to the stage of model development capabilities, there is an important strategy for my country.
Leave not subject to human autonomous space. If you abandon existing results, you hit the stove, redesign similar or
More complex new aircraft, the technical surface is very wide, the difficulty is very large, the time is very long, the fee fee
Force, in a fierce international competition, it is full of risk of failure.
At the 1981 National Division, the National Famous Aviation Specialty in the Chinese Academy of Sciences Wu Zhonghua
The family used to make a loudly, and the 10 "project cannot stop. The results cannot be lost, the team cannot be scattered." Transport
10 The results are only shelved today and have not been lost. As long as you pick up, adopt our country's grasp
Aviation new technology is improved, and the transportation 10 can build the air in my country's first high-Asian sound speed.
The load platform is first developed for the development of cargo transportation and military special aircraft, which is derived.
The selection of the series, or develop into a new model. We can use the national approach from the country from the country.
Supplement and strengthen existing development teams and assume this task.
This team is not easy to collect. More than 30 years, leadership of several generations of aviation pioneers
Under the Tao, this team is fighting on a large jet aircraft, and it is responsible for the total installation.
Two American jet passenger planes participate in international cooperation projects with various models of the United States and Europe, for large aircraft
And various technical topics have been widely extensive and profound, and obtain a series of major scientific and technological achievements.
Tired experience. If you use the so-called "things integration" approach to dissolve this development team, make this
The team is attributable to disappearance, but not only really "lost" in the 1970s, my country is not easy to come.
The aircraft develops results, and the bottom of the bottom of the air, making the development team of our civil aviation industry, and my country really returns to zero start.
In the 1950s, my country's start-up airplane design was formed, it formed advocated scientific research and development, independent design.
Excellent tradition of the aircraft model. This tradition is reflected in a series of new aircraft models developed in my country, and
It has achieved a good result of the victory and victory. my country's aviation industry has strong technical strength. Development
10 The backbone technology team is despised from the original air industry. But on the other hand, my country's aviation workers
There is also an old management system and development concept that is not compatible with productivity.
The productivity is played, causing the situation that has repeatedly defeated. If you play the flag of "Integration", abandon our country
The air design business is explored, realistic and innovative, cherish the fine tradition of the country's intellectual property rights, and keep and help
The long cause of the "repeated war and repeated defeat", due to the old, blind future backward concept and backward management
System, use only trees that do not see the forest philosophy thinking to guide my country's aviation industry, then
The management of the country has more funds to the aviation industry, even if it is a few decades, it will not receive any results ...
Not far from Yin Jian, the 20-year lesson of "lost" in the late 20th century, it is worth careful.
I firmly believe that in the 21st century, independence, self-reliance, reform and opening up, and innovative
In principle, "Technology is the first productive" principle, will eventually become the leading principles of my country's aviation industry.
