In order to improve the high-altitude performance of aviation piston engines, detailed design and research work were carried out from four aspects: one-dimensional theoretical verification calculation of heat exchanger, performance experiment, simulation of heat exchanger with air duct and UAV flight experiment. The one-dimensional theoretical calculation was carried out using the
