Unmanned ground effect aircraft with slide-way type adjusting device

Abstract

The invention provides an unmanned ground effect aircraft with a slide-way type adjusting device. The unmanned ground effect aircraft comprises an unmanned ground effect aircraft body and the slide-way type adjusting device arranged on the middle longitudinal axis in the unmanned ground effect aircraft body. The slide-way type adjusting device comprises a fixing shaft, a moving sliding block, a traction lock chain, a hydraulic mechanism and a gyroscope. By arranging the slide-way type adjusting device in the unmanned ground effect aircraft, the problem that takeoff power is excessive caused byoverlong sliding distance and insufficient lifting force when the ground effect wing aircraft is in a take-off stage is effectively solved; the problem of aircraft stall caused by excessive elevationangle at the moment when the aircraft is out of water surface in the take-off stage is further effectively solved, so that the ground effect wing aircraft takes off before reaching resistance peak ina short time and a short distance, the stability and safety during flight are ensured, and the installation of the device is simple and rapid.

Description

technical field [0001] The invention relates to the technical field of ground-effect aircraft, in particular, to an unmanned ground-effect aircraft with a slide-type adjusting device. Background technique [0002] Ground-effect aircraft is a new type of high-speed ship that uses ground-effect wings to generate additional lift. Seakeeping and high navigability are widely used in military and civilian fields, and have a broad market prospect, and have become one of the hot spots in the development of international ships in recent years. [0003] Although the research on wing-in-ground effect vehicles in various countries has made rapid progress in recent years and solved many technical problems, there are still many problems that need to be further improved and perfected. First of all, there is a resistance peak in the hydrodynamic performance of the WIG aircraft. The resistance peak is the process of the aircraft taking off in a floating state. When the speed increases, the ...

AI Technical Summary

Problems solved by technology

[0004] (1) During the take-off process, the resistance peak value is large, and the required take-off distance is long, so that the hull cannot be lifted off the water quickly;

[0005] (2) The moment the aircraft leaves the water, it will fly high rapidly or stall due to the excessive pitch angle

[0006] In view of the above problems, at present, we only start from the engine power and the line shape of the WIG hull, increase the power of the engine, provide greater thrust, and make it reach and cross the resistance peak, but this will increase the weight of the aircraft and weaken the carrying capacity. performance, and the cost is greatly improved; furthermore, the position of the step is controlled, so as to control the nose-up moment and balance the proportion of engine power and take-off angle of attack, but the control scale is difficult to grasp, and the control effect is not good
