The present invention relates to a multi-axis pintle propulsion engine, which is mounted on the rear of a guided weapon, and includes a combustion pipe having a combustion chamber inside and a plurality of nozzles provided at the rear of the combustion chamber to eject combustion gas generated in the combustion chamber, thereby enabling one-way propulsion of the guided weapon. The multi-axis pintle propulsion engine is provided in the combustion chamber and includes a hollow cylindrical solid propellant grain member, wherein an inner diameter groove is formed on the inner diameter surface of the solid propellant grain member along the circumferential direction of the inner diameter surface. According to the present invention, it is possible to generate greater thrust by increasing a combustion area even under a condition of a limited propulsion engine.

    본 발명은 유도무기의 후미에 장착되며, 내부에 연소실이 형성된 연소관 및 상기 연소실의 후방에 구비되어 상기 연소실에서 발생된 연소가스를 분출하는 복수 개의 노즐을 포함하여, 상기 유도무기의 편방향 추진이 가능하게 하는 다축 핀틀 추진기관으로서, 상기 연소실 내에 구비되며, 중공이 형성된 원통형의 고체 추진제 그레인 부재를 포함하고, 상기 고체 추진제 그레인 부재의 내경면에는 상기 내경면의 원주 방향을 따라 내경홈이 형성된 것을 특징으로 하는 다축 핀틀 추진기관으로서, 본 발명에 의하면, 한정된 추진기관의 조건에서도 연소면적을 증가시켜 보다 큰 추력 생성이 가능하다.
