The usage characteristics of modern UAVs make a higher request for reducing the structural weight. In order to reduce the structural weight of UAV, considering the special structural characteristics and flight con dition of the lift-fan UAV, the geometry optimization of the components is mainly conducted, so the parametric analysis procedures for the structural optimization design of the lift-fan UAV with ANSYS parameter design language（APDL） are established, and the parametric modeling, loading and solving of lift-fan UAV are a- chieved, as well as the result of the optimization are analyzed in detail. The result shows that the structural op- timization method of lift-fan UAV based on APDL is reasonable and efficient.
