摘要
为了明确不同机翼面积分布式电推进飞机设计方案的优劣,分别建立了相对常规布局飞机减小机翼面积进行巡航和起降多目标优化设计和机翼面积与常规布局飞机一致开展巡航性能单目标优化设计的流程;以某4座全电飞机为平台,开展了分布式电推进飞机的方案设计.仿真结果表明,相比于常规布局飞机,机翼面积不变的分布式电推进飞机设计方案巡航升阻比高、性能好.本研究对分布式电推进飞机的方案设计具有一定的参考价值.
Abstract
To determine the positive aspects and negative aspects of the distributed electric propul-sion aircraft design scheme under different wing areas,the multi-objective optimization design process of cruise and take-off and landing by reducing the wing area compared to the conventional layout aircraft was established,and the single objective optimization design process of cruise per-formance by keeping the wing area consistent with the conventional layout aircraft was carried out.On a four-seat all-electric aircraft,the design of a distributed electric propulsion aircraft was carried out.Simulation results show that comparing with the conventional layout aircraft the distributed elec-tric propulsion aircraft design scheme with constant wing area has higher cruise lift to drag ratio and better performance.This research may be beneficial for the conceptual design of distributed electric propulsion aircraft.
