The water tank was 3.66 m long, 0.46 m high and 0.3 m wide. The drawing shows the ‘Imperial College Fluid Motion Apparatus’, as it was called. Richards published in 1934 in Philosophical Transactions of the Royal Society shows that, in addition to wind tunnels, low speed experiments were being carried out in a water facility using an early form of particle image velocimetry. This had an open test section but it has not been possible to confirm if it was of the open or closed return circuit type.Īs with the 5 x 4 tunnel, no detailed information on the tunnel’s performance appears to remain. In 1931, a second low speed wind tunnel was built, known as the 2 ft (0.61 m x 0.61 m) open jet tunnel. It is known that one of the reasons for building the tunnel was to test models of airships, considered at the time to be important for the future of air transport.ġ931 - The 2' open jet tunnel Drawing of the Imperial College Fluid Motion Apparatus (1934) Unfortunately no photographs or drawings could be found of the Imperial College wind tunnel. The diagram shows the layout of a typical NPL type open-circuit wind tunnel. It is known that the tunnel was relatively large with a working section 5’ x 4’ (1.52 m x 1.22 m) and that it had an open-return circuit, a design known as the NPL type. The first wind tunnel in the Department is reported as having become operational in 1925. Funding was provided by the College to replace two of its existing low speed tunnels.ġ925 - The first wind tunnel in the Department of Aeronautics An NPL Type Open-Return Wind Tunnel (circa 1925) A further significant development occurred in 2017 when the Department moved from the Roderic Hill Building and the ACE extension to the refurbished City and Guilds Building. This laboratory, which opened in 1951, included new wind tunnel facilities which served the Department well for sixty years.
Sir Leonard Bairstow was followed as Head of Department in 1943 by Sir Arnold Hall FRS and during his headship he secured funding for a new aerodynamics laboratory. He had close connections with the National Physical Laboratory at Teddington and publications indicate that wind tunnels at the NPL, which could be reached relatively easily from Imperial College, were used from time to time for research by Imperial staff. Sir Richard Glazebrook was superseded in 1923 by Sir Leonard Bairstow FRS, renowned for his research in low speed aerodynamics. The wind tunnels that were in use after the 1950s are relatively well documented, far less is known about the facilities available during the Department’s first 40 years. One such area is low speed aerodynamics, made possible by having access to a wide range of wind tunnel facilities. During the 100 years since its establishment, the Department has been engaged in experimental work related to various aspects of aeronautics. The Department of Aeronautics came into being in the autumn of 1919 when Sir Richard Glazebrook FRS accepted the invitation to become its Head.
