HYDROCARBON FUEL SUPPLY SYSTEM FOR HYPERSONIC AIRCRAFT AND METHOD OF FUEL SUPPLY TO SYSTEM Russian patent published in 2018 - IPC B64C30/00 F02K7/10 

FIELD: aviation.

SUBSTANCE: invention relates to hypersonic aircraft [HAC] with ramjet reactive-air engines [RRAE]. In a hydrocarbon fuel supply system for a HAC containing RRAE with a combustion chamber, the system of active thermal protection of the HAC skin is made in the form of a cooling evaporative system with a heat carrier consisting of a capillary-porous structure with channels for supplying a coolant-water and removing its vapor. System contains a steam-petrol mixing machine, a fuel pipeline with a control valve and two manifolds located on the outer wall of the ramjet engine path. First collector with fuel feed holes is located behind the throat of the air intake, and the second collector is in front of the combustion chamber. Method of supplying fuel to the system includes supplying hydrocarbon fuel through a pipeline with a control valve to the first manifold and, through its openings, into the ramjet engine path. Other part of the fuel is vaporized by superheated water vapor in a steam-kerosene mixer and the steam-kerosene mixture is fed through a second collector into a two-circuit slit-like thermochemical reactor, and from there to a supersonic combustion chamber.

EFFECT: increased flight range is provided.
