Embodiment Construction

[0030] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0031] The purpose of the present invention is to propose a more effective ground effect flight control method based on scientific principles. In this new technical solution, first of all, a new control parameter concept for controlling ground effect flight is proposed, which is directly and effectively applied to control the two ground effect performance stages of IGE and OGE; secondly, through the automation technology The means are to realize automatic supervision and control of these new control parameters, and reduce the manual operation work share of the pilot of the ground effect flight. Third, through the development of application software, the flight performance management function of automatic optimization of ground effect flight is realized. Therefore, this technical solutio...

Abstract

The invention discloses a ground effect flight management system for ground effect vehicle, comprising a ground effect performance database, a wing vortex distance and under-wing airspeed detector, an error control and algorithm module, a processing platform, a video indication device, an audio warning device and a flight control device, wherein the wing vortex distance and under-wing airspeed detector is connected with the ground effect performance database, the ground effect performance database is further connected with the error control and algorithm module and the processing platform, and the video indication device, the audio warning device and the flight control device are connected with the processing platform; the maximal value of the wing-vortex distance of the designed ground effect vehicle is stored in the ground effect performance database, and the wing vortex distance and under-wing airspeed detector achieves measurement using an image recognition technique. The ground effect flight management system disclosed by the invention guarantees the safety in stable flight, and lowers the requirement on pilot vision for horizon observation, thus reducing the error in visual observation and improving the safety in ground effect flight.

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...
