The Aircraft Research Association (ARA) is an aerodynamics research institute in the north-west of Bedford.
History
The association was founded on 22 January 1952.[1] 14 main British aviation companies funded £1.25m to build a large wind tunnel.
It was first proposed in 1953 to build the site at Stevington, north-east of Bedford.[2] By March 1953, the current site was chosen.
Construction
Work started on Monday 7 September 1953.[3]
The wind tunnel was fabricated by Moreland Hayne of east London.[4]
The transonic tunnel first ran in April 1956. [5]
Visits
The Duke of Edinburgh visited on the morning of Friday 4 May 1956. He had been planning to land by helicopter in the south-east of Bedford, and to be driven from there to the site by car, but weather conditions were unsuitable.[6]
Structure
The site has the largest transonic wind tunnel in the UK, known as the TWT, with speeds up to Mach 1.4, powered by a Sulzer axial compressor. It is 25,000 hp electric-powered.
Wind tunnels
- Supersonic tunnel, Mach 1.4 - 3.5, built in 1958
 
Two hypersonic tunnels
- Mach 4-5 tunnel, built in 1965
 - Mach 7 tunnel, built in 1968
 
Research
Projects worked on include Concorde, the Harrier and most Airbus aircraft.[7] The Rolls-Royce RB211 was tested there.[8]
The site now works with RUAG of Switzerland.
