Rolls-Royce | How we assemble the Trent XWB; the world's most efficient aero engine
Avon Turbojet startup
The Rolls-Royce RB.41 Nene was a 1940s British centrifugal compressor turbojet engine. The Nene was a complete redesign, rather than a scaled-up Rolls-Royce Derwent with a design target of 5,000 lbf, making it the most powerful engine of its era. It was Rolls-Royce's third jet engine to enter production, and first ran less than 6 months from the start of design. It was named after the River Nene in keeping with the company's tradition of naming its early jet engines after rivers.
