DYNAMIC BRAKING OF A GAS TURBINE POWERED SHIP PROPULSION SYSTEM UTILIZING A D.C. ELECTRIC DRIVE
The patent relates to a system whereby dynamic braking of a ship's propeller powered by a turboelectric drive system is achieved by dissipating the rotational energy of the propeller through the windage loss of the gas turbine rotor. Braking torque on the propeller is maximized by controlling the generator field current according to a predetermined profile so as to maximize armature braking current without exceeding rated armature current or rated rotor speed.
