Abstract
A propulsion and electrical system for an aircraft including a turbine engine and a fuel cell. The turbine engine includes a turbo-engine, a fan having a fan shaft coupled to the turbo-engine, and a steam system. The steam system is fluidly coupled to a water source to receive water. The steam system includes a boiler to vaporize the water and to generate steam. The steam system can be fluidly coupled to the core air flow path to inject the steam into the core air flow path. The fuel cell is fluidly coupled to a hydrogen source and an oxygen source to receive hydrogen and oxygen, respectively, and, when receiving the hydrogen and the oxygen, to generate electricity and water. The fuel cell is fluidly coupled to the steam system as the water source.
