Embodiment Construction

[0027] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail.

[0028] The invention provides a method for testing muzzle efficiency, which specifically includes the following steps:

[0029] Step 1. Measure the weight M of the recoil part of the gun with and without the muzzle brake - , M 0 ;

[0030] Step 2, choose and match the special charge reduction charge, prepare the ammunition, and measure the weight ω′ of the charge reduction charge.

[0031] Step 3, making the collision plate 2, the steel ball 3, the rope 4, the bracket 5, the container 6, and the background plate 7;

[0032] The collision plate can be installed on the cannon 1, its surface is quenched, its thickness is not less than 30mm, and it is weighed (the weight is included in the weight of the recoil part);

[0033] There is a φ1 through hole in the middle of the steel ball 3,...

Abstract

The invention discloses a method for testing muzzle efficiency. By setting a collision plate and steel balls at the rear of the artillery, the collision method is used to launch a special charge-reducing ammunition under the condition of a standard artillery test belt and without a muzzle brake, and then Carry out relevant calculations, according to the momentum conservation and artillery design theory, first calculate the free recoil velocity and recoil kinetic energy of the artillery when the ammunition is reduced, and then calculate the muzzle efficiency η′ of the reduced charge t , full-charge and reduced-charge gunpowder gas action coefficients β and β′, structural feature K of the muzzle device, and finally calculate the full-charge muzzle efficiency η t , which reduces the number of measurement links, has the characteristics of convenient operation, small test workload and high precision, and can be used for the design and improvement of artillery muzzle brakes.

Description

technical field [0001] The invention belongs to the field of muzzle brakes, and in particular relates to a muzzle efficiency testing method, which is a method for testing the efficiency of muzzle brakes. Background technique [0002] The muzzle brake is an accessory device of the gun barrel, which is installed at the front of the barrel. By controlling the speed and direction of the gunpowder gas in the aftereffect period of the gun, the impulse of the combined force of the gun bore is reduced by means of momentum transmission, so as to reduce the The purpose of recoil kinetic energy to reduce the force of the gun mount. The muzzle brake reduces the kinetic energy of the recoil part, which is expressed by the muzzle efficiency, which is the main technical parameter of the design of the muzzle brake. [0003] The current test method is carried out in accordance with GJB2972, and there are two types: the free recoil test method and the resistance work test method: the free re...
