Abstract

Abstract:

Aerodynamics and stealth design optimization for a cranked flying-wing Unmanned Aerial Vehicle (UAV) planform is conducted based on the parameterized model and automatic meshing technology combined with the uni-and multi-objective optimization algorithm. The aerodynamic performance is predicted by numerically solving inviscid/viscous models, and the stealth performance is estimated through engineering methods. The optimal design front is given by the multi-objective design optimization. The conflict relationship between the aerodynamic and stealthy characteristics is identified, showing that improvement of Radar Cross Section (RCS) performance will lead to decrease of lift to drag ratio. This further indicates that the design of the flying-wing configuration needs consider the tradeoff between aerodynamics and stealth. Calculation shows that the viscous aerodynamic models should be used in the flying-wing design optimization. The design optimization method of aerodynamic-stealthy integration proposed can provide good foundation for the finer design of the flying-wing configuration of the UAV.

Key words: cranked flying-wing, flying-wing configuration, unmanned aerial vehicle (UAV), aerodynamics and stealth, optimization design
