(crossed out) X42-40 ORIGINAL (stamp) RE "GOSHAWK II" RADIATOR AND SUSPENSION. We send you herewith drawing LeC.1383 showing the above. This drawing also gives the form of the front cross member, and the brackets for the front suspension tubes of the engine. A fitting has been shown for the water inlet at the top of the radiator, but it is a little uncertain as yet where the thermostat will eventually be placed, as Mr. Royce suggests that we might get better results with the thermostat operating on the suction to the water pump. It is intended that "Goshawk II" shall be rigged up at first without thermostat and louvres, but the fan cowling should be fitted, and should be made large enough to accommodate the louvres. The drawing of this cowling, together with the fan, will be sent in due course. RECEIVED APR 28 1921 (stamp) The radiator suspension or fixing as now arranged consists simply of two pedestals standing on a somewhat flexible gusset plate which fixed the cross member to the frame, and is expected to give when one side member moves torsionally with relation to the other side member of the frame. The pedestals are formed on castings sweated to the sides of the matrix, these castings being securely fixed to the bottom tank by four 1 BA. screws and sweated. It will be seen that the forces necessary to hold the radiator are carried by large areas of solder in shear along the bottom and up each side of the matrix. The radiator filler is stood back from the front to give a deep chested effect and a bakelite cap is provided. A single vent pipe only should be used, but this has been made of ample diameter. The exterior portion of this pipe will be completed on the scheme for the fan cowling. E.{Mr Elliott - Chief Engineer} | ||
