FIELD: transport.
SUBSTANCE: to provide extra compressed air pressure for air cushion vehicle air with impeller running as compressor high-pressure gas-dynamic jet is created to escape from impeller nozzle. Said jet is forced into bottom supply channel composed in plan of confuser with neck-like nozzle and directed between vertical sidewalls. Confuser-like channel with nozzle extra high-pressure gas-dynamic jet is generated by moving vertical flaps secured to confuser vertical walls.
EFFECT: higher stability, reduced leaks from under the bottom, efficient operation thanks to maximum application of high-pressure compressed air at supply channel outlet.
