分布式电推进短距起降飞机的总体参数优化
Optimization for overall parameters of STOL aircraft with distributed electric propulsion
摘要
Abstract
The short takeoff and landing(STOL)aircraft using distributed electric propulsion is a novel concept,for which the design method of its overall parameters needs to be explored.Taking the conventional turboprop air-craft retrofitted with distributed electric propellers as an illustrative aircraft,the design problem of the aircraft over-all parameters is formulated as an optimization problem,and then the design optimization process for the overall air-craft parameters is presented using the optimization method with surrogate model.The results show that,after opti-mization for the overall parameters of the illustrative aircraft concept,the requirements for the ground roll distance during takeoff and landing can be met at the minimum weight penalty.The ground roll distance during takeoff is less than 100 m,the ground roll distance during landing is less than 70 m.The optimal results also indicate that the dis-tributed propellers are installed beneath the wing at a certain angle of inclination with moderate rotation speed and diameter,the wing area is increased slightly and required power for the turboprop engine is reduced significantly.关键词
