There is an emerging need for high-powered compact electrical generators to satisfy a wide-range of new generation defence applications.
Since mid-2008 Turbo Power Systems have been involved in a US defence program to develop a specialised high-speed generator capable of producing up to 1MW continuous output. To ensure compatibility with the downstream equipment fed from the generator, a customised fully-rated power conditioning system has been incorporated into the machine, including a local intelligent controller.
This fully integrated approach keeps the overall system as compact and lightweight as possible, resulting in an overall volume of less than 1 cubic metre and weighing less than 600 kg. The generator is designed to couple directly to the output shaft of a gas turbine engine, operating in excess of 20,000 rpm and has undergone a major validation programme to ensure performance and environmental compatibility thresholds are met.
Over the next few years we expect to see a range of different ratings of machines being made available to broaden the market for this technology, anywhere from 100 kW to 5 MW.
