Dynamic performance ground verification system of cable releasing device of towed secondary detonation fuel air explosive projectile

Abstract

The invention discloses a dynamic performance ground verification system of a cable releasing device. A projection device is erected through a ground rack, the cable releasing device is arranged on the ground, the throwing process of a secondary detonation device can be actually simulated. The dynamic performance ground verification system of the cable releasing device can effectively verify the cable towing and releasing condition and structural strength of the cable releasing device, the system lays a foundation for the design and verification of the cable releasing device in the towed secondary detonation guidance rocket fuel air explosive projectile fuse warhead matching, and the system has broad military application prospects.

Description

technical field [0001] The invention belongs to the technical field of secondary initiation cloud explosion bombs, in particular to a ground testing system for the dynamic performance of a towed secondary initiation cloud explosion bomb cable release device. Background technique [0002] The traditional secondary detonation cloud bombs mostly adopt the separate parachute deceleration and overall parachute deceleration schemes to reduce the bullet speed to below 60m / s at the moment of throwing, and realize the secondary detonation cloud by installing the secondary detonation bullet on the top of the deceleration parachute. There are the following problems in the coordination and detonation control of explosive bombs: 1) the application scenarios are mostly aerial bombs or surface-killing ammunition with low precision; 3) The separation of the missile body will cause complex design and reduce the hit accuracy of the ammunition; 4) The parachute deceleration has poor wind resis...

Problems solved by technology

[0002] The traditional secondary detonation cloud bombs mostly adopt the separate parachute deceleration and overall parachute deceleration schemes to reduce the bullet speed to below 60m / s at the moment of throwing, and realize the secondary detonation cloud by installing the secondary detonation bullet on the top of the deceleration parachute. There are the following problems in the coordination and detonation control of explosive bombs: 1) the application scenarios are mostly aerial bombs or surface-killing ammunition with low precision; 3) The separation of the projectile body will cause complex design and reduce the hit accuracy of the ammunition; 4) The parachute deceleration and wind resistance are poor, so the accuracy cannot be guaranteed

Directly carry out flight verification, the cost is high, and the test methods in flight verification are limited

If the ground verification of the dynamic performance of the cable-releasing device is not carried out, there is a risk that the actual release cable length is inappropriate or the tow cable breaks during the flight test, which will eventually lead to the failure of the guided rocket cloud bomb to achieve secondary detonation and its power cannot be exerted
