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.
