| To R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} c. to BJ. Wor.{Arthur Wormald - General Works Manager} c. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} c. to BY.{R.W. Bailey - Chief Engineer} X4003 X3366 X3822 Hs{Lord Ernest Hives - Chair}7/LG12. 8. 26. Attached herewith are valve open diagrams of the Curtiss engine compared with the F.10. The F.10 cams are the high lift type but they do not include the latest Falcon exhaust cam which gives longer duration open. The tests so far with the camshafts which have the longer exhaust valve cam show them to be an improvement. Hs.{Lord Ernest Hives - Chair} | ||
