Abstract

In order to solve the traditional killing of a high muzzle velocity grenade launcher after reducing recoil problem, a floating emission principle applied to high muzzle velocity automatic grenade launcher sitting subtracted design. The main issue is based on first startup device after internal ballistics theory and mechanical design theory 35mm grenades launchers floating recoil reduction and anti-fire devices blind design. First designed for the entire first start means the overall program and blind anti-fire devices; then designed the first start of the most important means of several core components: Houla An installed base, piston, rotating the chamber, the needle, as well as anti-Dud means pawl, detent spring, cam, slide lever, a rotary energy storage mechanism; and according to the given task condition (muzzle velocity, bullet weight, barrel weight) were within ballistics analysis derived from the sitting, which OK Houla an installed base and the basic dimensions of the front cover, and identified after the drawing process to provide energy without warhead ammunition loading dose; and finally the use of computer-aided design software and AutoCAD SolidWork institutional draw three-dimensional model and two-dimensional graph work, including the respective 3D assembly model, the two-dimensional assembly drawing, 2D parts diagram.

Keywords： 35 mm killer grenade launchers; Floating launch; The recoil; Starting starter; Misfire prevention device
