| To By. {R.W. Bailey - Chief Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} X3485 EFC {E. Fowler Clarke - Electrical Engineer} 4/T13.3.23. X.3485 - TAN FIBRE MATERIAL FOR GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) BALLAST RESISTANCE. Having made suitable tests with this material as a separator for the procelains in the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) ballast resistance, we have, from our experience, arrived at the conclusion that taken all round the material is not so suitable as the vulcasbestos which we are using. We return the sample of material herewith. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
