Rolls-Royce has started testing the first elements of what it says is the most powerful hybrid-electric aero power and propulsion system in aerospace at a newly renovated testbed. The tests support the 2.5-megawatt (MW) Power Generation System 1 (PGS1) demonstrator program for future regional airliners.
In a statement issued on June 3, Rolls-Royce said it has begun testing the AE2100 engine element and specialist controls and thermal management system, supported by a system integration generator, at its Testbed 108 at Bristol in the UK. It plans “later this year” to bring together a fully operational generator and a 3,000-volt power electronics system, now completing testing at Rolls’s facility in Trondheim, Norway, to start full PGS1 system testing.
