AIR CUSHION VEHICLE Russian patent published in 2006 - IPC B60V1/04 

FIELD: transport engineering; cross-country vehicles; hover craft.

SUBSTANCE: platform of vehicle is made in form of receiver of air masses delivered by machine plant with fan. Profiled slot is made over perimeter of receiver, over entire length of slot tip of aerofoil wing is arranged forming around receiver a wing with controlled flaps closed in plan to which peripheral flexible guard is attached. Upper and lower clearances are formed between edges of profiled slot of receiver and fitted in tip of wing. Said clearances are located over entire perimeter of slot. Vehicle is made with wing and flap guard from on-coming air flow when vehicle is running, and guard proper is secured at a distance from wing flaps over entire perimeter of vehicle. It is efficient to make wing with flap closed in plan with possibility of vertical displacement in width of profiled slot of receiver for fixing it in any point of displacement range with overlapping of upper or lower clearances in extreme positions.

EFFECT: increased lifting height of vehicle at preservation of specific power owing to aerodynamic relief of air cushion vehicle hull.
