HYPERSONIC AIRCRAFT Russian patent published in 2018 - IPC B64C30/00 F02K7/18 F02K1/12 

FIELD: aviation.

SUBSTANCE: hypersonic aircraft contains a fuselage, a ramjet air engine integrated with the lower part of the fuselage, and a starting propulsion system attached to the fuselage in series through an attachment and detachment device. Lower part of the socket surface of the jet nozzle of the ramjet air engine behind the critical section of the nozzle is made rotatable to the angle of 5–30 °, with respect to the horizontal axis, and is fixed from the rotation in the retracted, extreme upper position by a structural element of the starting propulsion system when it is attached to the fuselage.

EFFECT: invention is aimed at reducing the mass of the starting propulsion system and increasing the aerodynamic quality in an autonomous flight.
