Air cushion system of amphibious aircraft

Abstract

The invention aims at providing an air cushion system of an amphibious aircraft. The air cushion system comprises an airframe and an air cushion, wherein an air passage and a pressurization chamber are arranged in the airframe, an air intake fan is arranged on the airframe, the air intake fan is arranged at the inlet of the air passage, the air passage is communicated with the pressurization chamber through air passage air injection holes, the lower end surface of the pressurization chamber is provided with a bottom plate, air vents are arranged in the bottom plate; the air cushion comprises an airbag, the airbag is arranged below the bottom plate and is located outside the air injection holes, a cabin hydraulic press is arranged in the pressurization chamber, gaskets are arranged in the airbag, the top of a shock absorber is connected with the cabin hydraulic press, the bottom of the shock absorber is connected with the air cushion through the gaskets, the outside of the lateral side of the air cushion is provided with a web, the rear side of the air cushion is provided with a tailboard, the web is connected with a web hydraulic press, and the tailboard is connected with a tailboard hydraulic press. The air cushion system of the amphibious aircraft is suitable for various operating environments and complex terrains, has good buffer performance, is capable of improving the navigation speed on a water surface, the stability in high sea conditions and the safety during takeoff and landing, shortening the take-off and landing time, and enhancing the maneuverability and stealth performance.

Description

technical field [0001] The invention relates to an amphibious aircraft, in particular to an air cushion system of the amphibious aircraft. Background technique [0002] In recent years, the requirements for high-speed, reliability, and multi-environmental adaptability of surface and near-water vehicles have become higher and higher. Vehicles that can adapt to multiple environments, high-speed, and reliable operation are required, and this has also promoted the development of amphibious aircraft. become a research hotspot. Traditional seaplanes can only take off and land on the water surface, the operating environment is greatly restricted, and they are easily disturbed by wind and waves on the water surface. The process of take-off and landing is relatively dangerous, so it has not become a hot spot for development. [0003] Conventional amphibious aircraft consists of a fuselage and an inflatable air cushion, which can meet the operation and take-off and landing of various...

Problems solved by technology

[0005] 1. After searching, it is found that the air cushion system of the amphibious aircraft with inflatable cushion and paraglider involved in the patent application number CN201210209743.0 is an integrated structure system, which can be hung or inflated by inflating or inhaling is an income cabin and does not have a jet system

[0006] 2. After searching, it was found that the winged air cushion aircraft with end plates involved in the patent application number CN01809619.0 relied on the end plates on the wings and adopted a passive method to make the air flow form a high-pressure area at the bottom of the fuselage by itself, and the air cushion System lacks shock absorbers
