design feature

The gun adopts the principle of air conduction, the bolt is vertical wedge, and the barrel is equipped with a flame arrester; The two automatic guns are installed on the cradle with an inward inclination of 65438 0.8 degrees through the clamp and the rear guide rail, and the barrel is also supported by the retractable ferrule in front of the cradle, and a uniform gap is left between the barrel and the ferrule to reduce the vibration generated by the barrel during shooting; The artillery is supplied by the bullet chain, and each bullet box has a capacity of 40 rounds; The gun rack adopts a large trunnion structure, and the magazine boxes and magazine supports on both sides of the upper rack are simultaneously pitched with the cradle. The push balancing machine is installed right behind the upper frame, and the high-low machine and the directional machine are gear-driven structures, which are installed on the left and right sides of the bracket respectively. The firing mechanism can realize electric firing, pedal firing, manual firing and single firing respectively. The gun is equipped with WPO09 vector sight; Use WBO4 1P tracer to explode grenades and tracer armor-piercing incendiary bombs.

The left and right turrets are equipped with 1 ***2 35mm cannon KDA, which is manufactured by Oricon. There is a Doppler radar behind the upper part of the turret, which is used to locate enemy planes. There are also other optical aiming devices such as pre-monitoring system, TV camera, low-light-level TV camera, infrared identification device and laser rangefinder. The auxiliary power unit (APU) for machine power preparation is installed on the right side of the front of the car body. There are many mechanical equipment rooms on the left and right sides of the car body. Machine guns can also shoot horizontally at ground targets, and the additional benefit of the 74-type chariot body is stability; It can provide mobile shooting ability and inclined shooting ability. Compared with the 35mm L-90 2 antiaircraft gun also made by Oricon, the effective range and hit rate are greatly improved.

The appearance is very similar to the Flakpanzer self-propelled anti-aircraft gun in Germany, but the configuration of enemy radar and rear-end collision device is slightly different. The 35mm cannon is very powerful, and it is very powerful to shoot into the air or shoot at the ground. It also plays a role as a cover weapon for ground troops, and its positions can also be used for air-to-ground operations at the same time.
