Systems and methods for high bandwidth control of thrust response for turbofan or turboprop engines are provided. Such systems and methods include an engine control system (100) that processes a rate command (104) and a feedback signal (112) from an engine...

A method of operating a gas turbine engine (10B) in a low-power condition includes supplying fuel to a combustor (16B) by supplying fuel to a first fuel manifold (62A) and a second fuel manifold (62B) of the gas turbine engine (10B). The method also includ...

A fuel cell-atmospheric-pressure turbine hybrid system uses the thermal energy of a cell exhaust gas discharged from an atmospheric-pressure, high-temperature fuel cell effectively, does not need any additional emergency protective device, and enables the ...
