A rotary engine construction of radially compact dimension. The engine comprises a cylinder block contained in a cylinder canister. The cylinders extend in a radial direction and have open outer ends though which the piston rods extend. A combination flywheel/ring gear including reinforcing ribs is positioned axially adjacent the cylinders and sheave gears. The ring, located interiorly of the sheave gears, significantly reduces the radial extent of the ring gear. The reinforcing ribs are provided close to the location of engagement of the ring gear with the sheave gears, allowing the ring gear to be radially thin. The resulting engine is both radially and axially compact and significantly lighter than prior rotary engine constructions.
