Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, a high-sensitivity impact-triggered supersonic warhead fuze is based on the existing supersonic warhead fuze, a sliding seat 3 and a spring 5 are added to the head cavity of the fuse body 4, and the existing supersonic warhead fuze is added. The collision explosive element 2 in the warhead fuze is moved up to the sliding seat 3, the sliding seat 3 and the head cavity are in clearance fit, and the top surface of the sliding seat 3 is close to the cover foil in the existing supersonic warhead fuze 1 bottom surface, so that the collision and explosion element 2 is close to the cover foil 1, the sliding seat 3 is cylindrical, and there are two-stage through holes along its axial direction. The diameter of the first-order hole is larger than that of the second-order hole, and the collision explosion element 2 is fixed in the first-o...

Abstract

The invention discloses a high-sensitivity impact-triggered supersonic warhead fuze. A sliding seat and a spring are added to the cavity of the head of the existing supersonic warhead fuze, and the detonating element is moved up to the sliding seat. The sliding seat and the head There is a gap fit between the internal cavities, and the top surface of the sliding seat is close to the bottom surface of the cover foil of the existing supersonic warhead fuze, and the spring is arranged under the sliding seat. The trigger element can feel the aerodynamic thermal environment generated by the high-speed flight of the projectile at the head of the warhead fuze, and its sensitivity increases significantly with the increase of temperature. The sliding seat carries its inner triggering explosive element inertial forward, which helps to greatly improve the trigger sensitivity of the fuze, and is especially suitable for attacking weak targets such as hot air balloons and small drones. And when the service handling fuze head falls downwards, the falling speed is low, and the spring below the sliding seat will be pressed back to ensure the safety of the detonating element in the sliding seat.

Description

technical field [0001] The invention belongs to fuze technology, in particular to a supersonic warhead fuze triggered by high-sensitivity impact. Background technique [0002] For most ammunition, in order to achieve the desired damage effect, the fuze is often required to have a high trigger sensitivity. Fuze trigger sensitivity refers to the ability of the fuze to fire easily when the projectile hits the target. The fuze trigger sensitivity is related to the target type and mechanical (strength, density, energy, etc.) characteristics, the relative speed and attitude of the projectile, the size of the fuze trigger area, the sensitivity of the impacting explosive element, and the principle and structure of the trigger mechanism. [0003] The classic supersonic warhead fuze has a high-sensitivity impact trigger mechanism, mainly the impact flash cap (detonator) firing mechanism. This kind of firing mechanism has high sensitivity and good reliability, and has excellent perfo...
