Abstract
An aircraft with a motor bay is described; a motor system with a discharge duct; a heat exchanger arranged outside said motor system; a first air intake; a first duct along which the heat exchanger is arranged; a first converging nozzle having a downstream section fluidically connected with the discharge duct and with the first duct so as to create a first flow rate of air adapted to cool the heat exchanger; and a second air intake that is open in the motor bay and distinct from the first air intake; a second converging nozzle having a second downstream section fluidically connected with the discharge duct and with the motor bay, so as to create a second flow rate of cooling air of the motor bay directed from the second air intake towards the discharge duct and by-passing the motor system.
