Optimization of the design of ducted-fan hovering micro air vehicles using finite element simulation and orthogonal design

This paper presented a novel methodology to optimise the design of ducted-fan hovering micro air vehicles (MAVs). Based on flight stability studies of hovering MAVs and the theory of structural motion, various design parameters of ducted-fan hovering MAVs were studied and optimised using orthogonal experimental design. The orthogonal experiments are actually finite element simulations instead of physical experiments. Following the optimized results, the aircraft prototype was manufactured for experimental test using stroboscopic stereo imaging method and a purpose-built wind tunnel.
