Patent ID: 8522529

Claim:
A propulsive assembly for aircraft comprising a jet engine placed under a strut and a heat exchanger joined to an outside face of a box of the strut and taking a flow of cooling air and a flow of hot air from the jet engine, wherein the heat exchanger comprises a housing arranged at an angle relative to an axis of the jet engine so as to present two front faces, respectively forming a cooling air inlet face and a hot air inlet face, these cooling air and hot air inlet faces being directed towards a front of the jet engine and facing the flow of the air situated outside the exchanger, wherein the cooling air and hot air inlet faces have normals that are inclined relative to the axis of the jet engine, wherein the flow of hot air passes from the engine to the housing through a hot air intake duct passing through the box of the strut height-wise and the flow of cooling air passes through a cooling air intake duct passing through a pyramidal end of the strut, and the flow of cooling air and the flow of hot air circulate from front to back inside the housing, perpendicularly to each other and exit on different faces of the housing.
