AIRCRAFT WITH AIR-CUSHION LANDING GEAR Russian patent published in 2016 - IPC B60V3/08 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly to aircraft with air-cushion landing gear (ACLGA). ACLGA comprises fuselage, wing, vertical and horizontal fins, power plant, containing engine, connected with propeller, air-cushion landing gear (ACLG) equipped with fan, air duct, connected to AC chamber, throttle shutters, installed in air duct and equipped with their rotation drive. AC chamber is formed between chassis bottom, lateral skegs and located between skegs front and rear rotary shields, divided into sections along span and containing first link and second link connected to it. Each of shields is equipped with its release and retraction drive. Propeller shaft is kinematically connected with pump, which is connected with fan drive hydraulic motor by means of hydro transmission. In AC chamber intermediate plate is installed, dividing chamber into forward and aft parts. At that, throttle shutters are connected with drive with possibility to control air supply into forward and aft AC chambers. One of shields contains first link, which is pivotally connected with chassis bottom, and second link connected with first link by resilient element installed between links. At that, first link is connected with shield release/retracting drive by flexible link.

EFFECT: higher ACLGA stability by AC chamber pitch angle control, lower energy consumption for AC creation.
