Injector with tangential feed conduits for hydrogen-driven gas turbine engine

A gas turbine engine comprising:

• a combustor section having a combustion chamber;
• a hydrogen source;
• and
• an injector for introducing hydrogen from the hydrogen source and gas into the combustion chamber, the injector including
• a convergent-divergent nozzle head arranged along a nozzle axis and having an upstream end defining an inlet mouth, and
• a hydrogen/gas feed nozzle including
• a mixing chamber arranged along the nozzle axis upstream of the inlet mouth,
• first feed conduits configured to feed hydrogen into the mixing chamber, each of the first feed conduits being tangentially oriented to the mixing chamber, and
• second feed conduits configured to feed gas into the mixing chamber, each of the second feed conduits being tangentially oriented to the mixing chamber.
