The invention relates to a rotation-type pulse detonation engine. The cycle operation period of the rotation-type pulse detonation engine can be subdivided into the five processes of air suction, air exhaust, oil injection, ignition, detonation and jet. The rotation-type pulse detonation engine is mainly composed of an output shaft, an air cylinder, a rotor, a sealing pad and a bearing fixing plate. The output shaft and the rotor are assembled together through a spline. The output shaft, the sealing pad and the bearing fixing plate are installed together through bearings. The sealing pad, the bearing fixing plate and the air cylinder are fixed together. The output shaft with the rotor is located inside the air cylinder. Blades on the rotor divide the inside of the air cylinder into a plurality of fan-shaped body spaces evenly. The rotor, the sealing pad and the inner wall of the air cylinder form a closed detonation chamber which is also a fan-shaped body. The wall of the air cylinder is provided with air inlets, oil injection openings and lighting-up openings. The sealing pad is provided with jet openings, exhaust outlets and exhaust outlet adjusting devices. The detonation chamber is arranged in the spiral direction.
