A gas turbine engine with an electrically driven fuel pump unit wherein the rotor of the gas turbine engine operates an electric generator. The generator supplies two separate circuits. One circuit serves in the customary way to supply electricity for the flight system of an airplane or missile in which the gas turbine engine is used, while the second circuit is connected to an electrically driven fuel pump unit for the purpose of driving the latter. The circuit which is provided for the fuel pump unit can be at a higher electrical voltage than the circu...
A gas turbine engine having a compressor, a combustion chamber, a turbine, common rotor for the compressor and the turbine and a separate electrically driven fuel pump unit supplying fuel to the combustion chamber, an electrical generator arrangement supplying electricity to drive the fuel pump unit including electric generator means mechanically and coaxially connected to and mounted on said rotor so as to be driven directly by said rotor and at least two independent electric output circuits connected to said generator means, one of said circuits being ...
