Low-damage gun-launched experimental projectile and recovery method thereof

Abstract

The invention discloses a low-damage gun-launched experimental projectile and a recovery method thereof, and belongs to the field of low-damage gun-launched experimental projectiles. The projectile ischaracterized in that the housing of the projectile is converted from a standard cartridge case, a pointed end fuse of an original standard cartridge case is replaced with a flat head resistance cap,the flight time and range are extended by launching at a small elevation angle, the kinetic energy of the experimental projectile is consumed by the flat head resistance cap, and the high launching initial speed of the experimental projectile is reduced to a lower speed which meets the recovery demand; the impact on a case structure and a testing system is reduced by the deformation of the flat head resistance cap at the impacting moment; the landing point of the testing projectile is prejudged according to the launching direction, the launching small elevation angle and the pre-estimated initial speed; a recovery area is arranged at the landing point of the experimental projectile, the recovery area is filled with a buffering material which is used for recovering the experimental projectile to reduce the damage risk of the experimental projectile to achieve low-damage gun-launched experimental projectile recovery, and the method is particularly suitable for the recovery demands of the experimental projectile in a high-overload gun-launched experiment.

Description

technical field [0001] The invention relates to a low-damage shot test bomb and a recovery method thereof, belonging to the field of low-damage shot test bombs. Background technique [0002] A gun-launched missile is a missile launched by a cannon and boosted by a rocket engine after it is fired. Gun-launched missiles meet the new requirements of ammunition development in modern warfare with their advantages of high muzzle velocity, high benefit, and long range, and have developed rapidly in recent years. In the early stage of launch, under the action of the gun bore pressure, the propellant grain in the gun-launched missile will withstand an axial overload of up to tens of thousands of g, which will severely test the structural integrity of the engine grain. In order to study the structural integrity and safety of the propellant grain at the moment of launch of the gun-launched missile, it is necessary to conduct a gun-fire test to measure the dynamic mechanical response o...

Problems solved by technology

[0004] Aiming at the fact that the existing shot test bombs cannot meet the recovery requirements of the high overload (5000g-15000g) shot test, the technical problem to be solved by the low-damage shot test bomb and its recovery method disclosed by the present invention is: low-damage recovery of test projectiles, and can meet the recovery requirements of test projectiles fired with high overload
