64 FLIGHT, 13 July 1961 The new plostic wind tunnel at Hatfield Technical College (see item be low) THE INDUSTRY Plastic Wind Tunnel A NEW closed-circuit open-jet wind tunnel recently installed atHatfield Technical College is thought to be the first fabricatedfrom laminated plastic material. It was made by the Stanboro' Pattern and Model Makers Co Ltd from a combination of EpophenEpoxide resin, glass cloth and resin-impregnated glass mat. The idea of a plastic tunnel stemmed from discussions between thecollege and the Stanboro' Co, one of the companies invited to sub- mit quotations. Nearly 80ft long, the tunnel was designed by the aerodynamicsstaff of Hatfield Technical College in collaboration with the Stanboro' Pattern Co. Diameters range from a minimum of 2ftto a maximum of 4ft. The tunnel was fabricated in sections of various lengths from ioz glass cloth (Marglass 178/S/36), 2oz glassmat and Epophen Epoxide resin manufactured by Leicester, Lovell and Co Ltd, North Baddesley, Southampton. The grade ofEpophen resin selected has a slight natural resilience; a ""harder" resin could craze when subjected to the stresses which the wall ofa wind tunnel might have to withstand. Compressed Air Supply IN the design and installation of compressed-air equipmentprovided in the main plant room of the BOAC component testhouse at London Airport, James Howden & Co Ltd, 15 Gros- venor Place, London SW1, have acted as main contractors. Thisequipment is installed in the three air test cells and control room.

Function of the compressed-air equipment is to supply the aircleaned, dried and heated to three air test cells under any combination of flow, pressure and temperature, within the following ranges:flow, !0-2971b/min;pressure, 45-2651b/sq in: temperature, 35-404 C. The main compressor plant consists of five Howden positivedisplacement rotary compressors, each driven by a screen-protected squirrel cage induction motor. The compressors are so designed andconnected by pipe-work and valves as to allow for single-stage, two-stage and three-stage operation. Operation of the main compressor plant is carried out from amimic panel installed in the control room. From this panel the operator can select and start the compressors required for anyspecific duty, as well as the route by which the air is to pass through the plant and into the test cell where it is needed. The appropriatenozzle can be selected and the appropriate air heater put into or taken oul of operation. Final control and measurement of the Described as "Micro- cell's latest concep- tion in economy-class seating for mass air travel": the Double Travellite Mk 2. Weight of the double unit, inclusive of seat belts, is 431b; reclin- ing angle is 15-30 and seat pitch 29-36in temperature, pressure and flow in each of the three cells is carried out from the appropriate desk in the control room of the component test house.
