摘要： The invention relates to an aircraft propulsion system, which includes a turbojet and a heat exchanger system (200) which includes a main heat exchanger (202), a supply pipe (204) supplying hot air, a transfer pipe (222) transferring the hot air to an air management system, a main supply pipe (216) supplying cold air from the fan duct, an evacuation pipe (220) expelling the air to the outside, a sub heat exchanger (230) with a high pressure pipe (250) going through the sub heat exchanger (230), a sub supply pipe (232) supplying cold air and including a sub regulating valve (234), a sub evacuation pipe (236) expelling the air, a temperature sensor (223), and a control unit (224) which controls the system according to the temperature measured, wherein the sub regulating valve (234) comprises a door (240) articulated between a closed position and an open position, a return spring (242) which constraints the door (240) in the open position, and a realising system (244), controlled by the control unit (224), which is mobile between a blocking position and a realising position in which it releases the door (240) which is free to move to the open position.
This embodiment allows a supplementary cold air flow if necessary.-

摘要： The invention relates to a regulating valve (318) for a heat exchanger system of a propulsion system comprising a turbojet with a fan duct, and the heat exchanger system comprising a supply pipe which bleeds cold air from the fan duct, and wherein the regulating valve (318) has a front side (404) and a back side (406) and includes an open frame (402) which delimits a window (401) and is set in position in front of the supply pipe, two flaps (410a-b) rotatably mounted on the open frame (402) around a same rotation axis (412) located at the front side (404) between a closed position and an open position, a mechanism (420) linked to the flaps (410a-b) and mobile between a first position and a second position, and wherein the mechanism (420) moves the flaps (410a-b) from the closed position to the open position when it moves from the first position to the second position, and an actuator acting on the mechanism (420) to move it from the first position to the second position and vice versa.
The specific embodiment of the cold regulating valve reduces the necessary space to implement it.-
