Conceptual design of distributed electric propulsion aircraft with different wing areas
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.
