To Hs.{Lord Ernest Hives - Chair} From R.{Sir Henry Royce} c. to CJ. c. to BJ. c. to Wor.{Arthur Wormald - General Works Manager} c. to Ag. c. to Da.{Bernard Day - Chassis Design} c. to EY. c. to PN.{Mr Northey} c. to Hl. c. to EP.{G. Eric Platford - Chief Quality Engineer} c. to Hy.{Tom Haldenby - Plant Engineer} X766 R2/M9.6.22. RE. OVERHEATING OF GOSHAWK. X.766. X.4240. Mr. Elliott has pointed out that all overhead valve engines would suffer more quickly from loss of water because the exhaust passages are the first to become exposed, and not the cylinders, as in the case of the side by side valve engines. I think it would be as well for us to test the 40/50 engine for the effects of loss of water. I think also that the hawk engine should be retested. So far we hear that Hs.{Lord Ernest Hives - Chair} finds it difficult to damage the present head with overheating through loss of water - this needs confirming.- It may be that cracks were due to heating and initial casting stresses, and castings want making of less brittle metal, or annealing or ageing.
