Abstract
FIELD: aeronautical engineering. SUBSTANCE: heat exchanger cooling system consists of front inlet tunnel 1 and rear outlet tunnel 2 between which heat exchanger, adjusting gate and two-stage ejector are mounted. Ejector has first stage 7 and second stage 10. At high ambient temperature, for example during ground hold, air from engine compressor flows to ejector through branch pipe and causes intensified flow of cooling air through heat exchanger. During flight, heat exchanger is blown off due to velocity head. EFFECT: enhanced efficiency of cooling due to blowing of heat exchanger and reduced mass of device. 2 cl, 6 dwg
