BJ. Wor.{Arthur Wormald - General Works Manager} X8060 R3/M30.3.26. RE. E.16; F.10; PHANTOM & GOSHAWK HP. X.4099 X.8060 X.4114 X.5060 X.3804 It is evident that you have touched the defect in getting the gas in and out of these gx engines by the restriction in the valve bends, and what you have done has definitely improved matters. One now thinks that new cylinders for F.10, and new head for E.16, should be pushed forward with all speed, doing all we have decided and more if we can find a way of keeping the gas speed down, even lower than in any previous or competing engines. We should also look to the present Phantom, Goshawk and new aluminium head for Phantom. Do we want water between the inlet passages? Can it be made into a single chamber and entrance? 1.4/5 valves for Eagle approved. R.{Sir Henry Royce} | ||
