description The invention discloses a secondary-flow pintle rocket engine with a pushing force controllable function, relates to a pintle rocket engine, and belongs to the field of variable-pushing-force rocket engines in pneumatic and mechanical hybrid control. The secondary-flow pintle rocket engine mainly consists of pintle rocket engine basic devices such as a housing, a motor, a guide wheel, a combustion chamber, a pintle and a spray tube. The inner part of the pintle is hollowed out, a secondary-flow gas source is arranged in the hollowed-out part, and a secondary-flow jet hole is formed in the top of the pintle. During working, high-pressure secondary flow generated by the secondary-flow gas source is sprayed at the secondary-flow jet hole, and the jetted high-pressure secondary flow mainly has pushing force control effects as follows: firstly, the formed secondary-flow shearing layer is regulated to regulate the effective area of a throat part by regulating the pressure intensity and the flow rate of secondary fl
