HYPERSONIC AIRCRAFT Russian patent published in 2010 - IPC B64G1/00 B64G1/14 B64G1/62 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering and can be used doe delivery of various payloads to remote area of the Earth using aerospace start. Proposed aircraft represents tailless airplane with dual backswept vertical unit and control surfaces. Aircraft wing features pointed sweptback (70°-76°), forward and back wedge-like profile with maximum thickness at the chord center. Fusiform airframe features cone angle (6°-10°) of its nose is selected to have airframe located in the wing wind shadow in hypersonic flight conditions. Heatproof coat is applied onto aircraft surface. Note here that front edges of airframe nose, wing and vertical unit are made blunt. Aircraft flight is performed along programmed skip trajectory with initial departure angle varying from 5° to 8° and speed making (6500-7500) m/s. On entering atmosphere, aerodynamic force vector is changed by selecting optimum angle of attack. Random spread of trajectory parametres are compensated by aerodynamic maneuvering at cruising and descent trajectories at available aerodynamic control quality. Control program is based on forecast of aiming point (arrival into final zone).

EFFECT: increased range of flight due to control and minimum heat protection weight.
