FIELD: transport.
SUBSTANCE: invention relates to air-cushion vehicles. Proposed vehicle comprises propellers to generate air pressure under flat bottom between floats that make a skirt retaining air to keep vehicle afloat. Bottom is composed of parts arranged at different angles to allow accommodating turning rings with wing-like inserts under the bottom. Note here that forward jet thrust is generated by air flowing over snowmobile to create dynamic pressure at bottom profile section with wing-in-ground effect and jet pressure at swinging flaps at snowmobile front.
EFFECT: expanded operating performances.
