AIRCRAFT (VERSIONS), TAKEOFF-LANDING GEAR (VERSIONS) AND METHOD OF LIFTING AIRCRAFT IN AIR (VERSIONS) Russian patent published in 2016 - IPC B64C30/00 B64C9/36 B64C39/08 B64D37/06 B64C25/08 B60B19/02 G05D1/04 B64C13/04 

FIELD: aviation.

SUBSTANCE: aircraft according to each version comprises fuselage, supersonic wings, fuel tanks, engine and undercarriage. First version incorporates subsonic shoot back wings in combination with supersonic wings. Second version incorporates deflecting aerodynamic shield arranged in bottom of nose, front part of fuselage below centre-section under cabin and aerodynamically connected with wings. Third version has compressible fuel tanks, which are located in recesses for retracting chassis. Takeoff-landing gear for each version has a shock absorber strut. First version is made so that bogie of takeoff landing gear is arranged at landing gear bogie on one shock absorber strut. Second version is made so that takeoff landing gear has wing-support for landing gear. Method of lifting aircraft in air in first version involves acceleration along surface of runway, separation from its surface with subsequent release of takeoff landing gear so that it pushes through powder charges aircraft vertically upwards. During separation from surface of runway aircraft is taken to maximum angle of attack by pushing energy of front leg of takeoff landing gear with position of piloting control device at minimum angle of attack, when pitch controls are behind aircraft centre of gravity. Method of lifting aircraft in air in second version is based on front leg landing gear leg at a rate equal to speed of separation from surface of runway. Landing gear front leg is pressed and takeoff landing gear, pushing control handwheel completely from itself, and then landing gear front leg is lifted, taking wheel against stop. Method of lifting aircraft in air in third version involves releasing flaps, slats wing, wing outlet, reduction of installation angle of wing, engines, switching off brakes, removal of engines in takeoff mode. Wing mechanisation is released in position of takeoff, and reflecting aerodynamic screen shields bottom, at centre section of wings and nose - after taking to takeoff mode.

EFFECT: group of inventions is aimed at expansion of technical facilities.
