AIR-CUSHION AMPHIBIAN Russian patent published in 2010 - IPC B60V3/08 B60F5/02 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, namely, to amphibian with air-cushion landing gear. Amphibian comprises fuselage, engines with propellers, wing consisting of wing center section and outer wing, tail unit with aerodynamic control surfaces of inversed V-shaped and located to be blown by propellers airflows. Air-cushion landing gear with balloon skirt made up of flexible perforated envelopment which, when inflated, features toroidal shape, wheel landing gear and sliding support arranged inside said envelopment. Said sliding support represents trapezoidal plate made from flexible material. Plate larger side has shoe, while smaller side is hinged to fuselage bottom flat surface to be connected to toroidal surface of envelopment. Outer wings can have spars, the space between said spars being tightly communicated with wing center section inner space. Walls of outer wing rear spars can be furnished with perforations arranged over wing span separated from hinged rear flaperons by flexible curved walls. Lower sides of the latter can be attached to spar walls, under the perforated holes, while to upper sides jointed are boards pressed against flaperon upper surfaces and rear spar top flanges. Air-cushion landing gear can comprises radial-flow blowers to be mounted in wing center section. Said blowers can be could, via appropriate transmissions, with aforesaid engines.

EFFECT: higher safety due to improved aerodynamic and hydrodynamic characteristics.
