INTERNAL COMBUSTION PROPELLER ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; rotary engines. SUBSTANCE: proposed engine consists of cylinder on ends of which two heads with valve timing system and holes in center are installed and main shaft installed for rotation. Hollow axle is connected for movement through splines in middle of shaft. Said axle carries rigidly secured solid propeller-like two-sided piston, solid blade surfaces of which absolutely conjugated with propeller-like solid surfaces of two opposite heads.
