This is a description of a single-stage engine having a cylindrical rotor with four curved blades attached by means of free rotating rods. The curved blades have extended, half-round knobs on opposite sides, aligned with the top surface that fit in the extended hemispherical grooves on the interior side-walls of the housing. The egg-shaped housing facilitates the compression and exhaust cycles. The two housing halves are joined together at the center.

The three-stage engine comprises a compressor, which feeds air to a combustor for fuel injection, combustion and expansion of gases which rotate the rotor and generate torque. The afterburner receives the combusted gases from the combustor for secondary combustion and exhaust. Each unit consists of a cylindrical housing joined together on a common axis and a rotor mounted in an eccentric position of the housing sidewalls. The blades are similarly assembled as above.
