FIELD: mechanical engineering.
SUBSTANCE: invention relates mainly to turbine engineering, namely to gas turbine engines of small dimensions (microturbine engines), which can be used as a drive for an electric generator in hybrid vehicles, in small unmanned aerial vehicles, as well as in autonomous electric generators. In a microturbine engine containing a fixed housing 1, 19, a compressor wheel 6, a heat exchanger 7, a combustion chamber 8 and 9 with a fuel injector 15 and a glow plug 17, a nozzle device 10, 11 and an outlet pipe 18, a screw mounted on bearings is used as a rotor 2 with a multi-start external thread, which is located with a gap relative to the housing 1, 19, provided with grooves on its inner cylindrical surface.
EFFECT: said invention is aimed at simplifying the design and manufacturing technology of a microturbine engine, as well as increasing its efficiency.
