After the gun, the gun and the gun tube are not detained at the time of launch, rely on the gun remember to close the gun, the gun is sitting after the fire of the fire medicine gas, and the gun tube is not moving. The greatest advantage of this automatic mode is simple structure, good economical; the disadvantage is that the amount of gunpowder gas energy is not adjusted, and there is a harmful smoke that is discharged from the tail of the gun.
Free gun chair ---- gun machine and gun tube are completely free, can only rely on the mass of larger quality and rejection spring force from being launched backward movement after the laser is prevented. This free way is only available for small power automatic weapons such as pistols, submachine guns, etc.
Semi-free gun machine ---- semi-free gun machine is realized on a gun machine with some additional agencies in large delayed unlocking purposes. An important feature of it is that these additional agencies can provide considerable resistance when the pressure is high, so that the bullet after the launch is not excessive to avoid fried shells. As the pressure is lowered, the resistance is also lowered. This automatic way is used as Germany's G3 automatic rifle. A large advantage compared with the free gun console is that the locking mechanism is greatly reduced.
After the barrel, sitting (retracted) ---- When the warhead moves in the bore, the gun tube is firmly buckled, and then sits together, so that the warhead is blown away from the gun. After the unlocking action is completed. This automatic approach is used in an armored vehicle, as it can lock the crush compression is quite low, so that there is no more gunpowder pollution in the car. The distance between the gun and the gun is equal to or greater than the gun length used by the gun. It is called the gun tube, and after shooting; the gun tube and the gun are taken together, then unlock, the gun After the inertia continues, sit down to complete the retreat, arch, lock, and farten, etc.
Introduction ---- Using the gunpowder gas exported in the bore, take the gun chassis, the gun, the gun, etc., complete the automatic action. The greatest advantage of the air guiding weapon is that the amount of fireproofing gas exported can be adjusted by means of a gas adjuster as needed, which can reduce the failure rate at the time of shooting. At present, my country's light weapons widely use this automatic way.
Passage ---- belongs to the type of air supply, but does not use a piston. The gunpowder gas flows through the guiding tube after the air is emitted, and the energy is directly transmitted to the gun box, and then the gun is unlocked. The US M16 rifle, my country's improved 12.7mm large-diameter machine gun is all use this hair style. The advantage of this approach is that the weight of the active machine can be reduced. The ballistic trachea can easily produce dirt, residue, if not wiped in time, may malfunction.
The diameter ---- gun and gun tube are diameter. Line weapons refers to the distance between two relative rigs. The diameter is usually calculated in millimeters, titled 20 mm or less, called 20 mm.
The ribbon ---- also known as the loop, the wire in the gun is spirally uneven. The portion of the concave is called the jet line, and the raised portion is called the rigid line. The role of the ribbon is to rotate the warhead to keep the flight stability, improve the precision of the hit and increase the invasion. The existing weapons of our army has a ribbon.
Sliding ---- Into the inner wall of the glossy line of the line, the sliding weapon can shoot bullets, arrow-shaped bombs and tail stabilization.
Fire axis ---- Through the vision of the fire (such as a barrel) center.
Wrapped ---- Cars on any point on the ribbon line with the angle of the parallel line of the barrel axis. my country's 1954 pistol, 1956 assault rifle and the gun of the 1953 heavy machine gun are 5 degrees 42 points
Wrap ---- The wiring is wrapped in the barrel in the barrel. The multiples of the guide transition to the caliber are called wroughtance. The process of my country's rifle machine gun is 240 mm, approximately 3.15 times the muzzle, that is, wrap 3.15.
The gun mechanism ---- Light weapon gun mechanism can usually be used to complete a moving, latching, hairstyle, unlock, retreat, etc.
Acceleration mechanism ---- In some types of automatic weapons, the mechanism to accelerate the movement of the movement, such as in the short-situ weapon of the barrel, except for the handle, generally use the accelerator mechanism part of the barrel The energy is transmitted to the gun. The main role of the latching mechanism ---- The main role of the latching mechanism is to lock the tunnel when the weapon is launched, and the shell is taken to prevent the gunpowder gas from emit out and ensure accurate and reliable launch.
Trigger gravitational ---- weapon into the state of stay, the trigger makes the force needed. Trigger gravity should be moderate, too large, easy to change aim position; too small, easy to send.
Trigger Rover --- generally located below the machine, semi-circular or semi-oval, protects the trigger when its action prevents the occasion.
Block clearance ---- also called low gap. After the weapon is latched, when the latching support surface on the machine is close to the lock, the bullets are close to the barrel with the barrel and the gun tube, the distance between the bottom surface of the gun is called the bottom gap. . If the bottom plane of the gun is close to the bottom of the gun, the distance between the latching support surface on the gun box is referred to as a latching gap.
Guarantener ---- Connecting to the tube on the air-proof weapon, there is a piston, one end of the piston rod is connected to the active machine, when the emitting, the warhead is in the hall through the air hole, the gunpowder gas is made of this hole. Email, push the piston to complete the automatic cycle action.
Pilot hole --- the small hole on the air-air weapon gun, the gunpowder gas flows into the airway via this hole, and push the piston to complete various actions.
Mechanical aiming ---- Generally mean metal sight, such as surface rules, quasi-star and guidance, etc. The English terms are "iron anchor", which is relative to optical aiming.
Clearing aiming ---- a metal aiming, usually a small round hole on the slice of the sight, and aiming to target the target.
Optical Sight ---- Also known as optical sight, a target, and a lens, mirror body, and illumination device manufactured by optical principles.
Infrared sight ---- uses a near-infrared light source to illuminate the target, the target reflects infrared light, making photoelectric conversion imaging and performs night aiming instrument. Composed of an infrared search lamp, a photovoltaic transformer, a sight and a power supply, and the like.
The gun is high radiation sight. - A ring-shaped shrinking aimer is mainly used for air target shooting, consisting of the machine sitting and front and rear.
Micro-light night sight --- is like a reinforcerator as a core device, which does not have infrared detective lights, and the light reflected by the target under the weak light is enhanced by the enhancer. The visible image that can be perceived to observe and target the target.
Picture-style sight - is made by the illustrated door and quasios, when shooting. There are different shapes in the door: semicircles, rectangles, triangles, etc. Star also has different structural forms such as rectangles and triangles.
Aiming the disk ---- a hard wafer, the middle is a bullse, a small hole on the target, and then hanging on the wooden pile, it is used for training aiming.
Gaps ---- Also known as "photo door", part of the aiming device, usually on the surface, square, triangular, semicircular, and round wells. Mutual conscument baseline with starry stars for aiming.
Star ---- Part of the aiming device. It is usually located on the upper end of the muzzle. There are cylindrical, triangular, rectangular. Compaid with the surface tape gap to constitute a targeted baseline. Some can move in the direction and high and low to correct.
Commonly used surfaces ---- the same surface ruler "3" is based on the meter. The surface of the surface is usually expressed in "II" or "D". When the distance is not as measured in the battle, it can be used to target the lower part of the target under the target lower part of the target.
Aiming rod ---- a benchmark as a auxiliary aiming point to determine the correct direction angle and high low angle of the artillery. This term is used in artillery shooting.
Photoelectric measuring instrument --- is also known as a radius ranging instrument, a precision ranging instrument with modulated optical waves, and the measurement can reach about 25 kilometers, and can be used for night operation. Infrared spacing meter ---- Precision ranging with modulated infrared light, the measurement is generally 1-5 kilometers.
Laser rangefinder ---- Precision ranging instrument for laser is the light source. If the laser is continuous, the measurement can reach around 40 kilometers, and you can work all night. If the laser is pulsed, the absolute accuracy is generally low, but it can achieve a good relative accuracy for far distance.
Microwave Rangeter ---- Using Microwave Carrying Waves to Precision Ranging Instruments. Easy to operate, high ranging accuracy, more than 10 kilometers of measurement.
Hammer ---- It is used to combat the needle to enter a part of the gun. Hammer has two types of rotary and straightforward.
Hammer shaft ---- Turn the hammer to the axial pin of the weapon to have a certain position, and the hammer can be rotated thereon.
Hammer Wrench ---- The wrench on the exterior hammer is the ear, which is a small lever, which is easy to use hand to move the hammer.
Hammering Machine ---- A component of the firing mechanism is used to support the hammer.
