Special runway for wing-in-ground-effect vehicles

Abstract

The invention discloses a special runway for wing-in-ground-effect vehicles, which is characterized by comprising at least two slope runway units, wherein the slope runway units are in head-to-tail connection to form a staircase shape; and each of the runway units also comprises a slope runway and a horizontal runway. The slope runway borders a former runway unit; a certain angle is formed between the slop runway and the ground, two ends of the horizontal runway respectively borders the slop runway and a next runway unit, and the horizontal runway is parallel to the ground. A ground staircase shaped structure is adopted, and high-power thruseers which are needed in a water surface take-off and landing method are not required to be used, so that the problem of power mismatching in take-off and cruising in running processes of the wing-in-ground-effect vehicles is solved, the payload of wing-in-ground-effect vehicles is reduced, the total efficiency of the wing-in-ground-effect vehicles is improved, the manufacture cost of the wing-in-ground-effect vehicles is reduced and an upsizing development tendency of the wing-in-ground-effect vehicles is facilitated. Besides, the staircase shaped structure is adopted, two or more slope runway units are included, and therefore, the special runway is applicable to wing-in-ground-effect vehicles with different speeds of take-off and landing.

Description

technical field [0001] The invention relates to a special runway for WIG boats. Background technique [0002] WIG, also known as WIG, is an aircraft that sails close to the water surface or at high speed on the ground. Its flying altitude is very low, about half the height of the wingspan. The closer to the ground, the stronger the ground effect. Scientific research has shown that large-scale is the only way for WIG to enter the real practical stage and be used in the military. Russia and the United States, two major aviation countries, have proposed their own conceptual design schemes for ultra-large WIG. [0003] In order to save the cost of airport construction, the current wing-in-ground craft adopts the method of taking off and landing on the water surface. Although surface takeoff and landing can save the cost of airport construction, the power mismatch between WIG takeoff and cruise is an obstacle to improving its flight efficiency. Because WIG craft need to overcom...

AI Technical Summary

Problems solved by technology

The weight of the additional take-off engine will reduce the transportation efficiency of large WIG craft

At the same time, the way of taking off and landing on the water surface is relatively limited by the sea conditions. For example, the Russian 400-ton "Harrier" can only take off at a wave height of about 2.5 meters, which cannot fully meet the use requirements under the fifth-level sea state.
