Rotary blade engine

A rotary blade engine comprising:

• an outer cylinder;
• an inner cylinder;
• an output shaft;
• an operation chamber;
• a blade;
• a suction port;
• an exhaust port;
• a compressed-air chamber;
• an inlet flow path;
• and
• an outlet flow path,
• wherein the outer cylinder has a cylindrical inner peripheral surface,
• the inner cylinder has a cylindrical outer peripheral surface, is provided inside the outer cylinder, and rotates about a second center axis as a center of rotation, the second center axis being provided at a position eccentric from a first center axis of the inner peripheral surface of the outer cylinder,
• the output shaft is inserted into the inner cylinder, and rotates about the first center axis of the inner peripheral surface of the outer cylinder as a center of rotation,
• the operation chamber is formed between the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder,
• the blade is fixed to the output shaft, rotates together with the output shaft, and defines the operation chamber by floatably penetrating the inner cylinder from an inside of the inner cylinder and slidably contacting the inner peripheral surface of the outer cylinder,
• the suction port sucks combustion air into the operation chamber from an outside,
• the exhaust port discharges expanded air from the operation chamber to the outside,
• the compressed-air chamber stores air compressed in the operation chamber,
• the inlet flow path is a flow path for air flowing into the compressed-air chamber from the operation chamber, and is connected to the operation chamber in a vicinity of the exhaust port,
• the outlet flow path is a flow path for air supplied from the compressed-air chamber to the operation chamber, and is connected to the operation chamber in a vicinity of the suction port, and
• the air compressed in the operation chamber flows into and is stored in the compressed-air chamber by way of the inlet flow path, is sent to the operation chamber by way of the outlet flow path, and is expanded in the operation chamber.
