FIELD: machine building.;SUBSTANCE: invention relates to machine building, particularly, to aerosledge. Aerosledge include ski-boat, cabin installed on shock-absorbing elements, engine, propulsor, fuel tank, petrol pump, starter, accumulator, compressor. Skiing boat is made vehicle on pneumatic flow. Propulsor is represented by a low-power impeller in the form of a delivery device in the compressor mode. Air tube-step, fixed on the surface of the bottom of the boat-ski, allows not to resist from the bottom of the bottom of the boat-ski in motion. Small impeller nozzle in area of nose part is connected by its outlet end with compressed air directly to air tube-step inlet. Impeller nozzle with its side walls is connected through tubes with control keys to cavity of air cushions.;EFFECT: higher design simplicity and manufacturability.;7 cl, 8 dwg
