In order to solve the problem that single UAV cannot plan route independently since there is no communication mechanism between each other, an UAV route planning of bionic goose group path selection is proposed. Introduce the algorithm principle. After the UAV is initialized into particles, the host and the wing aircraft are identified in the UAV group. According to the basic principle of genetic algorithm, bionics is introduced into the planning of UAV group cooperative flying point plane. The genetic algorithm is used to plan the path of the host flight path of group flying, and the solution or optimal solution is generated. By simulating the strategy followed by the geese group, the algorithm of the downtime following the host was designed to realize the group flight. The flight test was carried out. The experimental results show that the research has certain reference value for UAV group flight control.
