Description
Technical Field
The invention belongs to the technical field of solid rocket engine charging, relates to a free charging mode of solid rocket engine charging, and particularly relates to a solid rocket engine for simulating the speed of a warhead moving armor breaking.
Background
When the missile finishes flying and the warhead starts to work, the whole missile has certain flying speed. The nail-breaking capacity of a general nail-breaking warhead is different from that of a static state in a motion state. In order to simulate the power of the broken armor part in flight, a rocket sled test is usually adopted, and an engine is used for providing power to enable the part to reach the required movement speed.
The engine adopted by the rocket pry test adopted by the warhead to break the armor is used for providing power for the rocket pry, so that the rocket pry is accelerated to a preset speed, and the warhead simulation breaking armor is completed. On the premise of meeting the reliability and safety, the engine can realize the preset movement speed of the rocket sled, has no strict requirement on the design weight, and has higher cost if a missile product engine is adopted to complete the rocket sled test, so that a simulation engine is usually designed to be matched with a warhead to complete the rocket sled test.
The analog engine generally has the characteristics of simple structure, low cost and the like. Meanwhile, the length of the rocket prying track is limited, so that the rocket prying track has the characteristics of short working time and high working thrust when the rocket prying track is required to reach the preset speed in the rocket prying test, and the simulation engine usually adopts a filling mode of filling a plurality of tubular explosive charges.
Once the loading pattern is determined, the working time, thrust, and total impact of the conventional multiple tubular charges are determined. However, the armor-breaking warhead may need different armor-breaking speeds during the simulation of the armor-breaking test, and the engine adopting the conventional multi-tube charging mode can only provide one armor-breaking speed, so that a plurality of engines need to be designed when different armor-breaking speeds are required.
Obviously, to meet the multiple warhead armor-piercing speed, a single engine using the existing multiple tubular charge loading approach is not achievable.
