Rolls-Royce says the hybrid-electric propulsion system it is developing for possible use on future regional airliners has achieved a key milestone of generating more than a megawatt (1 MW) of power in ground tests. Earlier this year, the UK-based aircraft engines manufacturer started testing the Power Generation System 1 (PGS1) with the goal of generating 2.5 MW, with further tests set to continue at the company’s renovated Testbed 108 facility in Bristol, UK.
