Aircraft demand conversion method, device and equipment based on engine characteristics and medium

The invention discloses an aircraft demand conversion method, device and equipment based on engine characteristics and a medium, and the method comprises the steps: giving a target demand power conversion model of engine power based on actual test data characteristics of a certain type of turboshaft-turboprop engine which is similar to a target engine configuration and has been subjected to high-altitude platform test verification; the actual power capability of the engine can be evaluated more accurately through the target demand power conversion model, and the method can be used for engine design based on aircraft demands, so that whether the designed state point can meet the aircraft full envelope demands or not can be judged in the initial stage of engine design; and the maximum power state point is judged according to the aircraft demand to guide the selection of the design point of the engine, so that the result after the engine completes the scheme design is ensured to be basically consistent with the
