Description

technical field [0001] The invention belongs to the technical field of engine thermal analysis, and in particular relates to a simulation analysis method, device and electronic equipment for thermal management of an aero-engine complete machine based on a fluid network method. Background technique [0002] As engine performance increases, the thermal load on the engine lubricating oil system and fuel system becomes higher and higher. At present, integrated thermal management systems are gradually used to manage and control the heat dissipation of aircraft and engines in a unified manner. [0003] The aircraft adds heat from the environmental control system, hydraulic system, and lubrication system to the fuel, and the engine fuel is supplied by the aircraft fuel tank. After cooling the lubricating oil system of the engine, part of it enters the combustion chamber to be burned, and the other part is cooled by ram air. Back to the aircraft fuel tank, the heat of this part of ...
