Generator for future hybrid-electric aircraft arrives at Rolls-Royce

The generator and related power electronics was delivered to Testbed 108 in Bristol from Rolls-Royce’s facility in Trondheim, Norway, having completed an extensive development test programme.

It will form part of the 2.5MW Power Generation System 1 (PGS1) demonstrator programme for future regional aircraft. In addition to hybrid-electric propulsion, the company said the generator could also be used as part of a “more-electric” system for larger aircraft or within future ground or marine applications.

PGS1 is said to form an important element Rolls-Royce’s sustainability strategy, which includes developing electrical power and propulsion systems.

In a statement, Rolls-Royce said it had 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.
