| To R. {Sir Henry Royce} from Hs. {Lord Ernest Hives - Chair} c. CJ. E. {Mr Elliott - Chief Engineer} BY. {R.W. Bailey - Chief Engineer} c. RG. {Mr Rowledge} CY. DA. {Bernard Day - Chassis Design} ORIGINAL Hs {Lord Ernest Hives - Chair} 5/T4.12.23. RE BRAKE TESTS. Attached herewith is a report on the analysis of the 20 H.P. footbrake. The brake was fixed to the back end of a Froude water brake; driving the brake was a 20 H.P. engine unit. It was arranged that we could vary the load on the brake and measure the torque. The results are comparative. We are improving the test tackle. Hs. {Lord Ernest Hives - Chair} | ||
