Description
Technical Field
The invention belongs to the technical field of secondary detonation cloud detonation bomb, and particularly relates to a ground test system for dynamic performance of a drag type secondary detonation cloud detonation bomb cable-laying device.
Background
The traditional secondary detonation cloud detonation bomb mostly adopts a scheme of separated parachute deceleration and integral parachute deceleration, the bomb speed at the moment of scattering is reduced to be below 60m/s, the secondary detonation type cloud detonation bomb is triggered and controlled in a manner that a secondary detonation bullet is mounted at the top of a deceleration parachute, and the manner has the following problems: 1) the application scene is mostly aeronautical ammunition or surface-killing ammunition with low precision; 2) the cloud blasting agent can only be thrown below 60m/s to form an optimal cloud cluster shape; 3) the separation of the projectile bodies can cause the design to be complex and reduce the hitting precision of the ammunition; 4) the parachute landing deceleration wind resistance is poor, and the precision cannot be guaranteed.
The war initiating system scheme of the towed secondary detonation guided rocket cloud detonation adopts an overall action mode of 'fixed-height throwing + delayed detonation'. The guided rocket explosive cloud is launched by a ground rocket cannon, a secondary detonating device is thrown out laterally when the guided rocket explosive cloud arrives at a certain height above a target, the secondary detonating device is fixedly connected with the guided rocket explosive cloud through a towing cable, the towing cable is arranged in a cable releasing device, the towing cable is pulled to be released to a preset length after the secondary detonating device is thrown out, and the guided rocket explosive cloud fall stably at a fixed relative distance after the relative motion of the secondary detonating device and the guided rocket explosive cloud is stable. And throwing the cloud explosive when the guided rocket cloud explosive bomb is at a certain height from the ground, starting delay detonation timing by the secondary detonation device, wherein the detonation delay of the secondary detonation device is the time required by the cloud explosive to form an optimal cloud cluster, and when the cloud explosive forms the optimal detonation cloud cluster, the secondary detonation device detonates the cloud cluster in the cloud cluster to form a cloud detonation effect to damage the target.
And a towing cable of the secondary detonating device is towed to determine the cloud blasting agent scattering time, and the relative distance between the secondary detonating device and the guided rocket determines whether the secondary detonating device is in the cloud cluster during the action. Whether the cable laying device can work reliably or not is directly related to whether the actual cable laying length meets the index requirement of the cable length matched with the lead war or not. The flight verification is directly carried out, the cost is high, and the test means in the flight verification is limited. If the ground verification of the dynamic performance of the cable laying device is not carried out, the risk of improper actual cable laying length or cable breakage exists in a flight test, and finally secondary detonation cannot be realized by the guided rocket cloud detonation bomb, and the power cannot be exerted.
