The Rolls-Royce Heritage Trust: The Rolls-Royce Spey

'The Rolls-Royce Spey' by Michael Hartley, published in the Technical Series of books by The Rolls-Royce Heritage Trust\n\nThe Rolls-Royce Spey was the company's second bypass jet engine developed for use in commercial transport; the first being the Conway (which was initially developed for military use). It first entered service in 1964 in the Trident 1 airliner operated by British European Airways, and went on to become the powerplant not only for later versions of the Trident, but also the BAC 1-11, Fokker F28, Gulfstream II and III civil applications as well as the Buccaneer, Nimrod, F-4 Phantom, AMX ground attack fighter and the Xian JH-7 military jets. In collaboration with the Allison Engine Company the TF41 engine was developed for the A7 Corsair, which was based on the Spey's core. The Spey also found success in marine form as the SM1A and SM1C in the Type 22 frigate in the Royal Navy. Other novel applications were demonstrated on the DHC Buffalo augmentor wing research.
