COMBUSTION IN HYPERSONIC AIR JET ENGINE Russian patent published in 2016 - IPC F02K7/12 B82Y30/00 

FIELD: engines and pumps.

SUBSTANCE: claimed process consists in the feed of air and primary fuel into combustion chamber to produce the primary fuel mix. Oxidiser and secondary fuel are fed into the combustion chamber to produce the secondary fuel mix. Note here that said combustion chamber is composed of serial main and extra combustion chamber communicated gas-dynamically. The primary combustible mix is combusted in the main combustion chamber while the secondary combustible mix is combusted in he extra combustion chamber. Hydrogen is used as the primary fuel. Unoxidised aluminium nanoparticles are used as the secondary fuel. Combustion products formed in the main combustion chamber are used as the oxidiser for aluminium nanoparticles.

EFFECT: augmented engine, higher critical altitude at normal overall dimensions.
