Pull type fuel air explosive secondary detonation device projection initial velocity calculation method

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.

Description

technical field [0001] The invention belongs to the technical field of secondary detonation cloud-explosion bombs, and in particular relates to a calculation method for projecting initial velocity of a secondary detonation device of a towed secondary detonation cloud-explosion bomb. 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 deceler...

[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
