Generator for Hybrid-electric Aero Power and Propulsion System Arrives at Rolls-Royce

The generator that will be at the heart of the most powerful hybrid-electric aero power and propulsion system in aerospace has arrived for installation at Rolls-Royce specialist testbed.

The generator, and related power electronics, was delivered to the newly-renovated Testbed 108 in Bristol, UK, from the Rolls-Royce facility in Trondheim, Norway, having completed an extensive development test programme. It will form part of the 2.5 megawatt (MW) Power Generation System 1 (PGS1) demonstrator programme, for future regional aircraft. In addition to hybrid-electric propulsion, the generator could also be used as part of a “more-electric” system for larger aircraft or within future ground or marine applications.

PGS1 forms an important element of our sustainability strategy, which includes developing innovative electrical power and propulsion systems.

Rolls-Royce has already tested the AE2100 engine element, specialist controls and thermal management system at Testbed 108.

Adam Newman, chief design engineer, aviation futures, Rolls-Royce, said: “We are excited to bring the generator to our new testbed and start fully integrating PGS1. This is a key milestone in the programme, bringing together the work of teams in the UK and Norway who have worked so hard to get us to this point. It is a great privilege to be involved in such important work – developing innovative electrical power systems is part of our sustainability strategy for the future.

“Our generator is about the size of a beer keg but it needs to produce enough electricity to continuously power around 2,500 homes – that is breaking new ground in terms of what is physically possible. On completion of testing, we will have a basis for megawatt-level power for future hybrid aircraft.”
