FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to ventilation system of heat-generating equipment arranged in external container of aircraft, including helicopter. Ventilation system of external heat-generating equipment located in external container of aircraft includes pipeline (11) connected to external container (8). Pipeline (11) includes central main line (14), which is connected to crew cabin (2) by means of air intake line (15), in which there is delivery fan (4) and check valve (5). Central main line (14) by means of fitting (10) is connected to at least one side main line (16), connected to external container (8) by means of adapter pipe (24), wherein auxiliary fan (6) is arranged in side main line (16). Pipeline (11) consists of sections interconnected by means of flexible collars (18). Adapter pipe (24) has at least one channel, which is fixed to the hole made in fastening flange (25), which is equipped with gasket (12) on the side of external container (8).
EFFECT: maintaining specified parameters of microclimate of heat-generating equipment arranged in external container of aircraft.
