Aiming at the problem of autonomous obstacle avoidance of fixed-wing UAVs, this paper proposes a safe flight corridor construction method based on the motion model of it, and realizes the path planning of fixed-wing UAV based on the safe flight corridor. At present, most of the planning-based obstacle avoidance methods for UAV are oriented to the rotor UAV. Because the motion of the fixed-wing UAV is limited by its minimum turning radius, and can not hover like the rotor, how to solve its optimal obstacle avoidance path is a problem to be solved. Firstly, according to the obstacle avoidance requirements of fixed-wing UAVs, standard path planning methods and flight corridor construction methods are introduced. Secondly, by modelling the fixed-wing UAV, the initialization corridor space required for its actual flight is solved by using the Dubins curve, and the initialization corridor is cut according to the front-end planning data and obstacle information to obtain the flight corridor for the safe flight of the fixed-wing UAV. The flight path of a UAV is optimized by taking flight corridor conditions as constraints. Finally, through simulation experiments, the superiority of this method in autonomous obstacle avoidance of fixed-wing UAV is proved.
