 A guidance strategy of landing for engine failed small scaled fixed wing unmanned aerial vehicle (UAV) was analyzed based on energy management. An on line dynamic pressure (DP) programming method based on altitude and distance to go (DTG) was proposed considering the safe flight envelope and energy profiles’ law for UAVs based on analyses for particle dynamics. In view of the dependence of the method upon the UAVs’ model, the idea of feedback control was introduced to revise the DP profiles in real time aiming at aerodynamic parameters’ inaccuracy. Semi physical simulations were designed and implemented on a fixed wing UAV’s flight experiment platform. Data show that the on line programming method with intervention of control can quickly lead the expected DP to the optimal value, and the precision of fixed point landing can be significantly improved. The landing guidance strategy can effectively achieve unpowered landing autonomously and stably.
