One of the important ways to break the endurance bottleneck of aircraft is to apply the flight strategy of albatrosses obtaining energy from gradient wind fields to glide thousands of miles on aircraft. Based on the body characteristics and flight strategy of albatross, a bionic albatross aircraft with bionic shape, aerodynamic layout and control mode is designed. The lift-drag ratio during cruise is 1.13 times that of conventional aircraft, and the maximum lift-drag ratio is 1.31 times that of conventional aircraft. The maximum drag is reduced by 12% and the wing root load is reduced by 35% through wing tip deformation. According to the behavior of albatross flapping its wings from time to time during gliding, the intermittent dynamic gradient wind gliding method is proposed, and the control performance simulation of bionic albatross aircraft is carried out. The results show that the error between the actual flight path and the gradient wind gliding path is less than 5%, and the energy consumption is 51.5% of uniform flight, which verifies the rationality of the intermittent dynamic gradient wind gliding strategy.
