AIRCRAFT Russian patent published in 2010 - IPC B64C29/00 B64C27/20 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to VTOL rotation-stabilised aircraft and can be used for research and reconnaissance purposes. Aircraft comprises airframe representing a body of rotation, one-channel system to control airframe in rotation conditions and aircraft start twisting device. Aircraft has wings arranged on its periphery, either in the plane of rotation or at an angle to it. The airframe upper surface features helical aerodynamic adapter to excite airflow vortex pattern. There are also one axial or several tangential turbojet engines to generate jet gas flow. Engine nozzles accommodate gasdynamic nozzles to generate the moment of rotation by dividing the thrust vector into axial and tangential components that are arranged on the airframe lower surface. Note that aforesaid axial turbojet engine nozzle represents a multi-start spiral nozzle. Above described wings can feature radially variable angle of attack and represent a mono-, binary- or rotor-cellular structure. Aircraft start twisting device can incorporate circle with rollers (in the case of one-time use) arranged above underlaying surface. In compliance with another version, aircraft lower surface can accommodate such appliances as articulated landing gear locked tangentially in twisting conditions.

EFFECT: expanded performances of aircraft with five degrees of freedom.
