To analyze the impact of electrical system thermal management on cruise performance and the selection of performance parameters under different operating conditions for the tilt-wing eVTOL,a tilt-wing eVTOL cruise simulation model is established by using the aircraft cruising speed as the control variable,the cruising time and electrical energy consumption as the objective functions,based on the 2D dynamics,drag,energy consumption and electrical system thermal management calculation model of the aircraft.Set different weights according to actual flight conditions,and optimize the solution based on the specific characteristics of the model using an improved particle swarm optimization algorithm.Taking the typical tilt-wing eVTOL aircraft Vahana as an example,performance parameters are obtained and compared.The simulation results show that the model has good optimization effects on reducing aircraft cruising time and reducing electrical energy consumption under various weight combinations.Compared to the most energy-efficient flight conditions,the fastest arrival can save about 50％ of time but also consume 120％ more electricity.Compared to the compromise of considering both time and energy consumption,the fastest arrival saves 20％ of time while consuming 28％ more electricity.
