Rolls-Royce’s hybrid-electric aero power and propulsion system has delivered more than a megawatt of power just weeks after going on test for the first time, reports the power plant manufacturer. Power Generation System 1 (PGS1) reached the milestone at the newly-renovated Testbed 108 in Bristol, UK. Testing is continuing with the aim of reaching up to 2.5 megawatts. PGS1 is a demonstrator aimed at proving technology for future hybrid-electric regional aircraft opportunities, and in addition the generator could be used within a “more-electric” system for larger aircraft or within future ground applications. PGS1 forms an important element of Rolls-Royce’s sustainability
