The National Gas Turbine Establishment (NGTE Pyestock) in Fleet, part of the Royal Aircraft Establishment (RAE), was the prime site in the UK for design and development of gas turbine and jet engines.
It was created by merging the design teams of Frank Whittle's Power Jets and the RAE turbine development team.
The largest test cell on site, Cell 4 was built in 1965, at a cost of £6.5 million, as part of the Concorde programme but also to test other supersonic jet engines.
The test cell, unique in the world, takes up most of the steel clad structure with its mass of pipes, blast doors and electronics.
It is connected to the Air House by blue pipes and was designed to simulate Concorde's flying conditions - Mach 2 (1522 mph) at 61,000 feet, but could test Concorde's engines at a maximum wind speed of 2,000 mph.
