HYPERSONIC AIRCRAFT Russian patent published in 2023 - IPC B64C30/00 B64D27/18 B64D37/06 

FIELD: aviation.

SUBSTANCE: invention relates to aviation. A hypersonic aircraft contains a fuselage, wings, fuel tanks, direct-flow engines, rocket engines and fuel component pipelines. Propeller gas turbine engines are installed on wings. Rocket engines are designed to run on oxidizer and propellant in the form of liquid oxygen and liquid hydrogen. The fuselage contains an oxidizer tank and tanks with first and second fuel. Oxidant piping goes inside first and second fuel tanks and is connected by pipelines to all rocket engines. The direct-flow engines are installed in wings and connected to the first propellant tank via fuel pipelines. The propeller gas turbine engines are desgined as three-shaft engines containing two propeller stages in the front part, have no gearbox with magnetic couplings between the turbocharger shafts and the propeller stages. The rocket engines are designed to rotate and lock in the vertical plane. The direct-flow engines are equipped with pivoting dampers for pitch control. Oxidizer and propellant pipelines are thermally insulated.

EFFECT: invention provides for increasing aircraft speed and efficiency.
