Rolls-Royce RB.44 Tay explained

The Rolls-Royce RB.44 Tay is a British turbojet engine of the 1940s, an enlarged version of the Rolls-Royce Nene designed at the request of Pratt & Whitney.^[1] It saw no use by British production aircraft but the design was licence built by Pratt & Whitney as the J48, and by Hispano-Suiza as the Verdon.^[2]

Two early production examples of the Tay were evaluated during 1950 by the Royal Aircraft Establishment (RAE) at Farnborough Airfield, Hampshire, in a specially modified Vickers Viscount.
