| To BY. {R.W. Bailey - Chief Engineer} from Hs. {Lord Ernest Hives - Chair} cc to EP {G. Eric Platford - Chief Quality Engineer} By been x5370 Hs {Lord Ernest Hives - Chair} 1/LG16.11.25. EFFICIENCY OF SERVOS. x5370 / x8370 +4388 From the appearance of the Halo taken off 103-MC we should say that these were not the cause of the inefficient servo. We should like to know whether any figures were taken of the efficiency of the servo. In the Experimental Dept. instruction on 4-wheel brakes, we gave complete particulars of how the efficiency could be measured. We have also supplied sets of spring balances to the Test Dept. We recommend that whenever there is any doubt as to the efficiency of the servo, the first and obvious thing to do is to measure the actual efficiency. Hs. {Lord Ernest Hives - Chair} | ||
