liquid propellant rocket engine, the aggregate, in
which due to the combustion or the decomposition (therm., katalitich.
and other.) fuel or its
components is manufactured the hot gas (temperature of 200-900
°S), which serves as working
medium for the drive of turbopump unit, the fuel-tank pressurization,
work of the system of control, etc. In g. most frequently
together are used the components of basic fuel with the values of the
coeff. of the surplus of the oxidizing elements, different from one.
Sometimes in g. is decomposed one of the components of basic
fuel (oxidizer or combustible),
for example, unsymmetrical dimethylhydrazine. Can be used and
vspomogat. rocket propellants. Depending on the composition of
the manufactured gas they distinguish it will restore, or it will
oxidize. G. osn. elements g. - mixing unit and housing.
