ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC F02B53/08 F02B55/14 

FIELD: motors and pumps.

SUBSTANCE: invention is related to propulsion engineering. Rotary internal combustion engine comprises body, shaft, combustion chambers with windows, inlet and outlet channels, and also internal and external structural units. Internal and external structural units are installed in body and create main unit and additional unit. Internal structural unit comprises annular disk with slots, where blades are installed. External structural unit comprises coaxial cylindrical tubular elements of the main unit and additional unit. Between coaxial cylindrical tubular elements of the main unit, accordingly, of larger and smaller diameters, annular elements are installed with wavy surfaces that create crests and cavities. Wavy surfaces of annular elements face each other, are equidistant and form working chambers together with external surface of cylindrical tubular elements of smaller diameter, internal surface of cylindrical tubular elements of larger diameter and end surfaces of annular disk. Inlet and outlet channels, accordingly, of the main and additional units, are arranged in every section of annular disk on one side from the blades. Combustion chambers are arranged in the form of cylindrical bucket divided into two sections by partitions, and are installed on the other side from blades in every section of annular disk with the possibility of rotation. Holes are provided in every section of combustion chambers.

EFFECT: higher factor of rotor internal combustion engine efficiency.
