Abstract

The invention discloses a bottom-concave shrapnel of a howitzer. The shrapnel comprises a fuse (1), a fighting part and a bottom-concave device (5), wherein a groove (6) is arranged at the bottom of the bottom-concave, the fuse (1) is arranged on the head portion of the bottom-concave shrapnel, the bottom-concave device (5) is arranged on the tail portion of the bottom-concave shrapnel, the groove (6) faces towards the outside of the bottom-concave shrapnel, and the fighting part is arranged between the fuse (1) and the bottom-concave device (5). According to the bottom-concave shrapnel, the low-pressure vortex intensity of the shrapnel bottom is reduced through the bottom-concave device, a local vacuum region is filled by air, then the pressure of the shrapnel bottom is improved, the bottom resistance is reduced, the correctness of projectile chamber movement is improved, the outer trajectory performance is improved, the flight stability of projectiles is improved, the air resistance is reduced and the accuracy of projectiles is improved.

Description

technical field [0001] The invention relates to the technical field of ammunition, in particular to a concave grenade of a howitzer. [0002] Background technique [0003] Howitzers, especially 105mm howitzers, have the advantages of light weight, small size, flexible maneuverability, and can be airlifted or hoisted by helicopters. They are suitable for rapid deployment of troops and are used as direct fire support weapons in the implementation of medium and low-intensity operations. A multi-purpose weapon that can play a prominent role in various military operations, it is an ideal ground suppression weapon for mountain troops and special forces. Moreover, for the armies of some developing countries, howitzers, especially 105mm howitzers, are still the standard equipment of infantry divisions (division-level main guns). According to relevant statistics, the number of different types of 105mm howitzers in various countries in the world is currently equipped. It accounts f...
