Abstract
An engine system for an aircraft having an engine with a combustion chamber and a turbine unit, a first injector manifold for the combustion chamber, a second injector manifold arranged downstream of the turbine unit, an auxiliary conduit and a thermal loop with a first heat exchanger on an auxiliary conduit for dihydrogen, a second heat exchanger where the second injector manifold is oriented toward the second heat exchanger and conduits between the heat exchangers so as to heat the dihydrogen circulating in the auxiliary conduit before its arrival at the injector manifolds.
Claims7
An engine system for an aircraft having a tank in which dihydrogen is stored, the engine system comprising:
- an engine with a combustion chamber and a turbine unit arranged downstream of the combustion chamber;
- a first injector manifold arranged in the combustion chamber;
- a second injector manifold arranged downstream of the turbine unit;
- an auxiliary conduit arranged to transport dihydrogen from the tank to the first injector manifold and the second injector manifold;
- and
- a thermal loop comprising:
- a first heat exchanger arranged on the auxiliary conduit upstream of the first injector manifold and the second injector manifold,
- a second heat exchanger arranged so that the second injector manifold is oriented toward the second heat exchanger, and
- a plurality of conduits fluidically connected between the first heat exchanger and the second heat exchanger so as to heat dihydrogen circulating in the auxiliary conduit before the dihydrogen arrives at the first injector manifold and the second injector manifold.
