Rolls-Royce has started testing the first elements of the most powerful hybrid-electric aero power and propulsion system in aerospace at a newly-renovated testbed. The tests are part of the 2.5 megawatt (MW) Power Generation System 1 (PGS1) demonstrator programme, for future regional aircraft.
Rolls-Royce has begun testing the AE2100 engine element and specialist controls and thermal management system, supported by a system integration generator, at our Testbed 108 in Bristol, UK.
Later this year a fully operational generator and a 3,000-volt power electronics system, currently completing testing at our facility in Trondheim, Norway, will be brought together to start full PGS1 system testing. The generator can be used either for hybrid-electric propulsion systems or as part of a “more-electric” system for larger aircraft.
PGS1 forms an important element of our sustainability strategy, which includes developing innovative electrical power and propulsion systems, as well as further improving gas turbine performance and promoting the use of Sustainable Aviation Fuels.
