Description

technical field [0001] The invention relates to a management system, in particular to a ground-effect flight management system for a ground-effect aircraft. Background technique [0002] The ground-effect aircraft takes advantage of the compressibility of the air to obtain the "air cushion" effect by flying close to the ground (or water surface); at the same time, it uses the ground effect to reduce the induced drag of the wing, effectively improve the lift performance, and achieve high-speed navigation. [0003] The air pressure difference between the upper and lower surfaces of the wing forms lift, but it also causes the lower airflow to circulate upwards. This airflow that surrounds the wing upwards is called a vortex. The vortex reduces the lift efficiency of the wing, and seriously affects flight safety. When the aircraft is flying close to the ground, due to the suppression of the ground surface, the trajectory of this vortex is changed from a circular trajectory in t...
