test ammunition
1.For the fuze setback arming of a projectile, there are two main force environments, one is a projectile launched in the bore, and another is the force environment of the 1.5 m drop test of ammunition from the standard.
2.How to make correct judgment, to ensure service management especially the 1.5 m drop test of ammunition and take advantage of the inertial force from launched environment in the bore to reliably arm the setback arming device is what this paper concerns. That is to say, on one hand the truncated conical shells are protected in the 1.5 m drop test of ammunition, on the other hand the inertial force in the bore collapses it.
4.Abstract: This paper discuss the selection of typical ammunition and storage test environment, sets up safety model and reliablity model about semi-combustible cartridge, presents the test items of storage reliability, and preliminarily determines the sampling opportunity and sample book quantity.
5.Methods Based on the theory of hydrodynamics and ammunition, to analyze the influence of the bullet diameter, form, construction, terminal velocity and mass on the tested effects. Results The test results have proved that the small bore bullet possesses the ideal wounding effect. Conclusion Small bore(5￣6 mm), higher muzzle velocity (900￣1 000 m/s) and small mass (3￣4 g) for bullet are the developing direction.
