The invention discloses a boosting device for an aerospace liquid propeller. The boosting device comprises a main pushing device, a left auxiliary device and a right auxiliary device, and is characterized in that the main pushing device comprises a shell, a heat insulation layer is welded to the inner wall of the shell, an upper sealing plate is welded to the top of the shell, and a combustion chamber is welded to the inner wall of the bottom wall of the upper sealing plate; a fuel gas channel is formed in the middle of the combustion chamber, an ignition device is welded to the inner wall ofthe top of the fuel gas channel; the end, away from the ignition device, of the fuel gas channel is sleeved with a thrust control device; and one end of the thrust control device is sleeved with a conical spraying pipe. The left auxiliary device and the right auxiliary device are arranged on the two sides of the main pushing device, the inner structure of the left auxiliary device and the inner structure of the right auxiliary device are the same as that of the main pushing device, so that the auxiliary pushing effect can be achieved when the device is started; the top cover is arranged to bestreamline, so that wind resistance can be reduced; and guide plates are arranged on the outer walls of one sides of the left auxiliary device and the right auxiliary device to further reduce air resistance.

    本发明公开了一种航空航天液体推进器用助推装置,包括主推装置、左辅助装置与右辅助装置,其特征在于,所述主推装置包括外壳,所述外壳内壁焊接有隔热层,所述外壳顶部焊接有上密封板,且上密封板底壁内壁焊接有燃烧室,所述燃烧室中间设置有燃气通道,且燃气通道顶部内壁焊接有点火装置,燃气通道远离点火装置的一端套接有推力控制装置,且推力控制装置一端套接有锥型喷出管。本发明通过在主推装置两侧设置左辅助装置与右辅助装置,且左辅助装置与右辅助装置的内结构与主推装置相同,所以在启动装置时能够起到辅助助推的作用,且将顶盖设置为流线型,能够减小风的阻力,在左辅助装置与右辅助装置一侧外壁设置导流板能进一步降低空气阻力。
