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

Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] Such as figure 1 As shown in Fig. 1, the triggering system scheme of the towed secondary detonation cloud bomb adopts the overall action mode of "fixed height throwing + delayed detonation". The cloud bomb is launched by the ground rocket, and when it reaches a certain height above the target, the secondary detonating device is thrown sideways. The secondary detonating device is fixedly connected with the cloud bomb through the tow cable. After throwing out, the towing cable is released to a predetermined length, and after the relative movement of the secondary detonating device and the cloud bomb is stable, the two maintain a fixed relative distance and fall steadily. When the cloud explosion bomb is at a certain height from the ground, the cloud explosion agent is thrown, and the secondary detonation device starts to delay the detonation timing. ...

Abstract

The invention discloses a pull type fuel air explosive secondary detonation device projection initial velocity calculation method. Through the pull type fuel air explosive secondary detonation deviceprojection initial velocity calculation method, uncertainty conditions of pull type fuel air explosive secondary detonation are comprehensively considered, and a maximum velocity difference calculation expression positively related to maximum stress of a towing rope is given; accordingly, the optimal projection initial velocity range of a secondary detonation device can be determined, the strengthallowance of the towing rope is ensured to be large as far as possible so as to realize secondary detonation. The pull type fuel air explosive secondary detonation device projection initial velocitycalculation method lays a theoretical basis for the design of the projection initial velocity in pull type fuel air explosive secondary detonation fuze warhead coordination and has wide military application prospects.
