Abstract: The system including an internal combustion engine provides the motive power source to the main and tail rotor systems of a helicopter. The engine has a rotating annular cylinder which is rotated in a predetermined ratio to oscillation of a plurality of pairs of oscillating pistons in the cylinder, the pistons being so oscillated so that adjacent pistons are moved alternately apart from one another and toward one another for the respective strokes of the internal combustion engine and having intake port, exhaust ports and ignition means on the rotating annular cylinder located by the rotation of the cylinder between adjacent pistons according to the firing order and cycle of the engine in a typical four stroke cycle system. The engine includes the use of unitary in place of articulated, oscillating crank arms to transmit power from the torque tubes to the crankshaft, and the use of pistons having gabled surfaces that are rigidly connected to the torque discs.

Abstract: An internal combustion engine provides the motive power source to various types of aircraft using a ducted fan. The engine has a rotating annular cylinder which is rotated in a predetermined ratio to oscillation of a plurality of pairs of oscillating pistons in the cylinder, the pistons being so oscillated so that adjacent pistons are moved alternately apart from one another and toward one another for the respective strokes of the internal combustion engine and having intake ports, exhaust ports and ignition means on the rotating annular cylinder located by the rotation of the cylinder between adjacent pistons according to the firing order and cycle of the engine. The engine includes the use of unitary in place of articulated, oscillating crank arms to transmit power from the torque tubes to the crankshaft, the use of pistons have gabled surfaces that are rigidly connected to the torque discs, and fan blades attached to the rotating annular cylinder providing the air thrust for propelling the aircraft.

Abstract: An improvement in an internal combustion engine having a rotating annular cylinder which is rotated in a predetermined ratio to oscillation of a plurality of pairs of oscillating pistons in the cylinder, the pistons being so oscillated so that adjacent pistons are moved alternately apart from one another and toward one another for the respective strokes of the internal combustion engine and having intake port, exhaust ports and ignition means on the rotating annular cylinder located by the rotation of the cylinder between adjacent pistons according to the firing order and cycle of the engine. The improvements include the use of unitary in place of articulated, oscillating crank arms to transmit power from the torque tubes to the crankshaft and the use of pistons having gabled surfaces that are rigidly connected to the torque discs.
