FIELD: engines.
SUBSTANCE: invention relates to rotary engine rotor. Rotary engine rotor 10 comprises housing 12, insert 14 and fixing element 16. Housing 12 has outer surface 18 and inner surface 22. Outer surface 18 comprises three sides 20, arranged in form of equilateral triangle. Inner surface 22 comprises mounting sections 24, each located at center of rotor side 20. Mounting sections 24 form mounting opening 26. Mounting section 24 first fixing seat 28 extends outwards from inside from surface 22 to surface 18 partially so, that prevents destruction of surface 18. Cooling channel 30 passes in axial direction through housing 12 in area of each vertex 31. Insert 14 is located in mounting opening 26. Insert 14 support part 38 has second fixing seat 40, directed radially and aligned with seat 28. Fixing element 16 passes through seat 40 and located in seat 28.
EFFECT: technical result is higher versatility of rotor design and reduced risk of gas leaks between rotor housing outer and inner surfaces.
