Abstract
A gas turbine ignition system (40) in accordance with the invention includes a power takeoff (42) coupled to the turbine for providing rotary power upon rotation of a rotor of the turbine; a clutch (48) having an input (46) coupled to the power takeoff and an output (50) which outputs torque applied to the input when the rotor is rotating at a velocity less than a velocity at which the turbine is self-sustaining and which does not output torque when the rotor is rotating at a velocity at least as great as the self-sustaining speed without control from an external source; a permanent magnet generator (52) coupled to the output for generating electrical power in response to the rotation of the rotor; and an ignition system (16) powered by the electrical power generated by the permanent magnet generator for producing ignition pulses coupled to a combustor within the turbine until the output of the clutch is disengaged from the input.
