FIELD: transport.
SUBSTANCE: group of inventions relates to aircraft and vehicles with air (static and dynamic) unloading, in particular self-stabilised ram wing machines of A, B and C types. The ram wing machine (RWM) contains a hull, a propulsor, a bearing plane of small lengthening (PSL) with end floating washers, retractable front and back protections of a static airbag, stabilisation and control devices. The bearing PSL is implemented in the form of a centre wing of small lengthening (CW) which is made in the longitudinal direction at least of two PSLs - the front PSL with a nose guard and flaperons and the back PSL with flaperons. Under the centre wing within the boundaries of its projection to the horizontal plane a cavity of static AB (StAB), under the front PSL - a cavity of dynamic AB (DAB), under the back PSL - a cavity of static and dynamic AB (SDAB) are made. At the complex increase of aerodynamic and transport characteristics of RWM including the creation of the necessary carrying power (CP) by means of the elevated pressure zone between the bearing PSL and the bearing surface the natural character of dependences of CP value and the positions of focuses of the bearing PSL from the angle of attack and height of flight is changed by the creation in the longitudinal direction of at least two local zones of formation of CP - front and back, with points of their application on a longitudinal axis respectively in front of and behind the centre of mass.
EFFECT: improvement of the safety of flight and manoeuvres, increase in the bearing ability and height of flight in the mode of the screen effect, reduction of sizes, improvement of runway characteristics, water tightness, expansion of functionality and range of operational centring, improvement of convenience of operation and maintenance is achieved.
