The Ce-Liner aircraft developed by Bauhaus Luftfahrt is selected as our research target, and the C-wing assembly is based on a non-planar three-surface configuration: main wing, side wing and top wing. This work implement software to simulate whether Ce-Liner can reduce the generation and strength of wingtip vortices during cruise, and whether it can improve the efficiency of the aircraft with better economic benefits. Our findings revealed this Ce-Liner configuration can increase the lift-to-drag efficiency by about 20 percent during cruise. Also since it’s an all-electric aircraft, it can greatly reduce the weights of the turbofan engine and fuel, thus the high-lift devices can be eliminated. Furthermore, this Ce-Liner will not need to stock fuel in the main wing, hence the thickness and weight of the wing could be further reduced. In addition, it is found that this aircraft configuration has a stronger crosswind resistance capability due to our gust crosswind simulation.
