ROTARY ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: engine housing has split between head and tail parts; compressor has three-stage blades; blade stages are arranged at different angles to longitudinal axis of compressor; guide stage of blade located at entrance is inclined through 40-50 deg, intermediate compression stage, through maximum 10 deg, and discharge stage, through 70-80 deg, compressor surface is divided into a number of identical sectors for gradual increase of guide stage length in each blade within prospective sector limits and for formation of air intake cavity; compression stage of each blade has its thickness gradually increasing towards discharge stage; the latter has constant thickness and its side surfaces form, together with those of adjacent blades, interblade slit channels; turbine rotor is of three-stage design; first stage has cylindrical surface further turning into second stage; made in inner cylindrical surface of tail part of engine housing are cavities whose axes are arranged at angle of 60 deg to plane crossing axis of revolution and point of intersection of plane axis and inner surface of tail part of housing. EFFECT: improved design. 7 dwg
