Optimization Design of Distributed Propeller Position Based on MOEA/D Algorithm

Distributed propulsion technology can be used to improve the takeoff and landing performance of aircraft. However, while the propeller slipstream increases the wing lift, it also the drag, which may lead to a decrease in the lift-drag ratio, thereby affecting cruise performance of the aircraft. Therefore, it is necessary to optimize distributed propellers for improving the cruise performance. The installation position is one of the key parameters of distributed propellers and has a significant impact on the aerodynamic performance. Thus, the MOEA/D algorithm is used for the optimization design of the distributed propeller position. Results show that the optimized configuration has a larger lift-drag ratio, indicating that optimizing the installation position of distributed propellers can improve the cruise performance of aircraft. Moreover, the MOEA/D algorithm can be used for the selection of distributed propellers, providing an important reference for the design of distributed propulsion aircraft.
