Abstract

The embodiments of the present invention provide a power processing method and device for a flying car. The method includes: obtaining state parameters of the operating state of the flying car; performing iterative calculation of theoretical values based on the state parameters of the operating state and basic aerodynamic data to obtain the power value of the flying car in the operating state; generating the total power of the flying car under the state parameters of the current operating state according to the power value. By adopting the combined means of theoretical calculation and CFD, the basic aerodynamic data with fewer calculation cases is obtained by using the CFD method, and the data source of theoretical calculation is supplemented. While improving the accuracy of theoretical calculation, the power values of the whole machine of the flying car at different hover altitudes, different forward flight speeds, different climbing speeds, and different takeoff weights can be quickly calculated, and the power requirements corresponding to the complete speed-altitude envelope can be obtained, so as to provide parameter basis for power selection. Since the calculation workload of CFD is greatly reduced, the effects of low calculation cost and high timeliness are achieved.
