High-sensitivity impact-triggered supersonic nose fuse

Abstract

The invention discloses a high-sensitivity impact-triggered supersonic nose fuze. A sliding seat and a spring are additionally arranged in a head cavity body of an existing supersonic nose fuse, a collision explosion element is moved upwards into the sliding seat, the sliding seat is in clearance fit with the head cavity body, the top face of the sliding seat is tightly attached to the bottom face of a cover foil of the existing supersonic nose fuse, and the spring is arranged below the sliding seat. The collision explosion element can sense an aerodynamic thermal environment generated by a bullet flying at a high speed at the head of the nose fuse, the sensitivity of the collision explosion element is obviously increased along with temperature rise, as the collision explosion element is tightly attached to the lower portion of the cover foil, when the fuse collides with a target at a high speed, the sliding seat carries the collision explosion element in the sliding seat to move forwards inertially, and therefore the trigger sensitivity of the fuse is greatly improved, and the high-sensitivity impact-triggered supersonic nose fuze is especially suitable for attacking weak targets such as hot-air balloons and small unmanned aerial vehicles; and when the fuse head falls downwards during service handling, the falling speed is low, the spring below the sliding seat can be pressed to retreat, and therefore the safety of the collision explosion element in the sliding seat is guaranteed.

Description

technical field [0001] The invention belongs to fuze technology, in particular to a high-sensitivity impact-triggered supersonic warhead fuze. Background technique [0002] For most ammunition, in order to achieve the ideal damage effect, it is often required that the fuze has a high trigger sensitivity. Fuze trigger sensitivity refers to the ability of the fuze to ignite easily when the projectile touches the target. The trigger sensitivity of the fuze is related to the target type and mechanical (strength, density, energy, etc.) characteristics, the relative velocity and attitude of the projectile, the size of the trigger area of ​​the fuze, the sensitivity of the detonating element, and the principle and structure of the trigger mechanism. [0003] The high-sensitivity impact trigger mechanism of the classic supersonic warhead fuze is mainly the impact cap (detonator) ignition mechanism. This type of ignition mechanism has high sensitivity and good reliability, and its ...
