The cold air propelling attitude control power system comprises a cold air supply unit, a cold air output port is formed in one side of the cold air supply unit, the cold air output port communicates with at least two branch air pipes, each branch air pipe is provided with a pressure reducing valve, and the pressure reducing valve is connected with the cold air supply unit. The end, away from the cold air output port, of the branch air pipe communicates with a plurality of branch air pipes, and the tail end of each branch air pipe communicates with a thrust chamber. The attitude control power system has the following predictable technical effects that the scheme that the multiple pressure reducing valves are connected in parallel is adopted, the development difficulty of a single pressure reducing valve is remarkably reduced, meanwhile, simultaneous work of the multiple thrust chambers is achieved, the attitude control requirement is met, the requirement is met, the development difficulty is reduced, and the development period of the whole attitude control power system is indirectly and greatly shortened.
本申请涉及一种采用多减压阀的冷气推进姿控动力系统,包括供冷气单元,所述供冷气单元的一侧设置有冷气输出口,所述冷气输出口处连通有至少两根分路气管,每一根所述分路气管上均设置有一个减压阀,所述分路气管远离所述冷气输出口的一端连通有若干根分支路气管,每一根所述分支路气管的末端均连通有一台推力室。本申请具有以下可预期的技术效果:采用多减压阀并联的方案,显著降低了单个减压阀的研制难度,同时实现了多台推力室同时工作,满足了姿态控制需求,既满足了需求又降低了研制难度,间接大幅度减少整个姿控动力系统的研制周期。
