SHIPBOARD POWER PLANT WITH SHAFT GENERATOR Russian patent published in 1995 - IPC

FIELD: shipbuilding. SUBSTANCE: power turbine 1 of main gas turbine engine 2 of power plant is kinematically linked with AC three-phase generator 4 built in shaft of fixed-pitch propeller 3; turbocompressor of gas turbine engine is coupled with attached generator 7 by means of decoupler 6. Power outputs of generators 4 and 7 are electrically connected via rectifiers 10 and 11 with common inverter 14 of static current frequency converter 15. When ship is running at cruising and full speeds, generator 4 coupled with propeller is operating; when ship is running at slow speed and in maneuvering, ship's mains is supplied from generator 7 which is not coupled with propeller rotated by turbocompressor of gas turbine engine and not provided with mechanical rigid coupling with power turbine of gas turbine engine. EFFECT: enhanced reliability. 1 dwg
