Fowler Clarke - Electrical Engineer} X4384 FC AUG 12 DA {Bernard Day - Chassis Design} /T1/G10/8/21. RECEIVED X4384 X4383 RE "GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II" MOTOR AND DYNAMO. X1640 Would you please issue the necessary information to the Experimental Dept. to enable them to make up a dummy model armature complete with winding on each of the above machines, as per Mr. Royce's instructions. The armature itself should be made of wood with the slots cut in and mounted on a rough spindle, then wound with the insulation and winding which we have already instructed to you. The object is to see whether the winding can be got into the estimated space or not, etc., and we wish these armatures to be sent to "Camacha(Henry Royce's office in West Wittering)" as soon as possible. Also please send further copies of the winding drawings on above windings for our information. DA. {Bernard Day - Chassis Design} | ||
