FIELD: engines and pumps.
SUBSTANCE: proposed propfan engine comprises turbo compressor with housing, compressor, combustion chamber with its outlet communicated, via das duct, with turbine and two-stage propfan. One stage of the latter is coupled with compressor via magnetic coupling, while another stage is coupled with the former via reversible reduction gear. Magnetic coupling comprises half-coupling arranged in compressor, for example on its vanes, and drive half-coupling mounted on turbo compressor housing. Propfan stages are arranged inside fairing.
EFFECT: higher efficiency and reliability.
