AERODYNAMIC GROUND-EFFECT CRAFT Russian patent published in 2008 - IPC B60V1/08 

FIELD: transport.

SUBSTANCE: invention relates to aeronautical engineering, namely, to production of dynamic air-cushion vehicles, in particular to aerodynamic ground-effect crafts and ground-effect machines exploiting, to some extent, the ground effect. The aerodynamic ground-effect craft incorporates a frame, air relief and thrust creation means, stabilisation means. The air relief and thrust creation means are made up of an air blower power unit and an air duct arranged in the frame rear, as well as an air intake chamber representing a hemisphere space with a spherical surface in the frame bottom and with a radius making half a bottom width and allowing boosting the air by the said air blower power plant through the air duct into the hemisphere. The frame is shaped so as to realise a function of a bearing wing. The air blower power plant can be made up of an engine/engines and a turbosupercharger/turbosuperchargers or composed of a fan/fans and engine/engines driving the rotary propelling fans. The aerodynamic ground-effect craft can incorporate a shutter arranged between the said air blower power plant and the air duct arranged in the frame rear. The stabilisation means can represent keels making a horizontal and vertical empennage. Note that the horizontal empennage area and position of its arm from the centre of gravity of craft are selected so as to ensure its lengthwise static stability margin less than 0.15 subject to the pitch angle. The aerodynamic ground-effect craft can be furnished with the support elements representing pontoons attached to the frame bottom. Alternatively, the frame bottom can be shaped so as to realise the support element function.

EFFECT: higher efficiency of air relief and thrust means, higher aerodynamic performances, reliability and cross-country capacity.
