Multifunctional rocket based on rocket ejection seat

Abstract

The invention provides a multifunctional rocket based on a rocket ejection seat. The multifunctional rocket comprises a combined lifesaving rocket and a long exhaust nozzle assembly, wherein the long exhaust nozzle assembly is arranged beside the combined lifesaving rocket and is fixedly connected with the combined lifesaving rocket, and the long exhaust nozzle assembly comprises an electric exploder, an air-entraining connector, a blocking plug and a long exhaust nozzle; the air-entraining connector adopts an air channel of a three-way structure, one end of the air-entraining connector is fixedly connected with the combined lifesaving rocket, the blocking plug is placed in the air-entraining connector, a gap air channel is reserved at one end of the long exhaust nozzle so that gas generated in a working combustion chamber of the lifesaving rocket can enter, and the other two ends of the air-entraining connector are connected with the long exhaust nozzle and the electric exploder respectively. When the electric exploder works to generate fuel gas, the fuel gas pushes the blocking plug through the air-entraining connector and moves along an inner cavity of the air entraining connector until the fuel gas makes contact with the long exhaust nozzle, at the moment, the fuel gas in the combustion chamber is blocked by the blocking plug, and the long exhaust nozzle stops working. The multifunctional rocket is simple in structure, quick in response and high in lifesaving success rate.

Description

technical field [0001] The invention belongs to the technical field of solid rockets, and is used for ejection lifesaving of a rocket ejection seat, in particular to a multifunctional rocket based on a rocket ejection seat. Background technique [0002] In the field of aviation lifesaving, lifesaving rockets provide secondary power for ejection seats to ensure lifesaving safety under low-speed and 0-0 ejection. In the ejection process of a multi-seat model, in order to ensure that the movement of the seats does not interfere, the seats are required to be able to change the trajectory quickly. Therefore, when multiple seats are ejected, life-saving rockets and divergent rockets that meet the overall requirements are often required to provide secondary power and trajectory divergent moments for the seats. [0003] There are usually two thrust schemes for the ejection of existing ejection seats with multiple seats. One is the scheme of using life-saving rockets and divergent r...
