基于无水肼的RBCC发动机一体化燃油供应系统

本发明公开了一种基于无水肼的RBCC发动机一体化燃油供应系统，火箭推力室和冲压燃烧室用同一系统实现一体化燃油供应与调节；系统采用四氧化二氮、无水肼和煤油三种可贮存推进剂，用无水肼催化分解分别驱动两个涡轮泵，并在系统充填时挤压供应至火箭推力室，实现与四氧化二氮自燃点火；无水肼采用单贮箱挤压式供应，推力室和燃烧室通过涡轮泵实现推进剂供应；推力室身部通过四氧化二氮进行冷却，冲压燃烧室利用煤油进行冷却。本发明克服了组合发动机对火箭推力室和冲压燃烧室各自采用独立供应系统导致系统复杂、难以实现一体化再生冷却结构设计等问题，满足组合发动机一体化燃油供应与调节，系统总体相对简单，容易实现。

Rocket based combined cycle (RBCC) engine integrated fuel supply system based on anhydrous hydrazine

The invention discloses a rocket based combined cycle (RBCC) engine integrated fuel supply system based on anhydrous hydrazine. A rocket thrust chamber and a ramjet combustion chamber achieve integrated fuel supply and adjusting through the same system. The RBCC engine integrated fuel supply system adopts three storable propellants of dinitrogen tetroxide, the anhydrous hydrazine and kerosene, two turbine pumps are driven through catalytic decomposition of the anhydrous hydrazine, and the anhydrous hydrazine is extruded and supplied to the rocket thrust chamber during system filling to achieve spontaneous ignition with the dinitrogen tetroxide; the anhydrous hydrazine is supplied in a single storage box extruding mode, and the propellants are supplied to the thrust chamber and the combustion chamber through the turbine pumps; and the body of the thrust chamber is cooled through the dinitrogen tetroxide, and the ramjet combustion chamber is cooled through the kerosene. Through the RBCC engine integrated fuel supply system, the problems that systems are complex, and integrated regenerative cooling structural design can not be achieved easily due to the fact that the rocket thrust chamber and the ramjet combustion chamber adopt independent supply systems respectively in a combined engine are solved, the requirement for integrated fuel supply and adjusting of the combined engine is met, and the whole system is relatively simple and easy to realize.
