FIELD: aviation.
SUBSTANCE: invention relates to the field of aircraft engineering, in particular, to the design of unmanned, as well as manned helicopters, mainly, with internal combustion engines equipped with cooling system. Helicopter comprises fuselage, main rotor, tail boom, engine equipped with cooling system. Cooling system includes radiator/radiators with air intake/air intakes and cooling agent nozzles. At the same time radiator/radiators with air intake/air intakes are installed in rear part of helicopter in area of start of tail beam at distance from rotor shaft equal to 0.2–0.8 of radius of main rotor and on side part/side parts of helicopter.
EFFECT: higher efficiency of cooling and repairability while maintaining good aerodynamic characteristics of helicopter.
