After being redeployed from Unilever to a small firm just outside Rugby in May 1940, Bob Feilden played a key role in the development of Whittle’s jet engine, working with his colleagues to transform the jet from theory into practice.

Starting with the early history of Whittle’s jet engine and its early testing, Feilden takes us inside the firm to give us a first-hand account of the jet’s flight trials, in the Gloster E28/39 and how they overcame the technical challenges to develop the W1 engine into the W2, W2/500 and W2/700.

Feilden also explores how the firm looked to make the engine fit for the ill-fated Miles M52, the plans for the LR1 Turbofan, the relationship between Power Jets and Rolls-Royce and how the team broke up in 1946 after nationalisation.

The lecture was also published as a Hodgson Prize winning paper for the Aeronautical Journal in February 1993. Royal Aeronautical Society members can access the paper for free via www.aerosociety.com/elibrary.
