The R52 wind tunnel at the Farnborough Royal Aircraft Establishment was built in 1917 and was designed to test scale models, rather than entire air frames like the Q121 tunnel across the road (previous Ello post). The R52 tunnel could generate a wind speed of around the speed of sound (740mph), which gave the tunnel the title the 'Transonic Tunnel.
The control room here has changed little since the 1930's and there many bits of machinery left in-situ that date back to the same period. The building is a fantastic time capsule and a glimpse back in time to an era when Britain ruled the world in terms of its scientific and engineering prowess. These buildings played a huge role in the early development of aircraft, bomb and missile casings, boats and many other vehicles.
