X. 790 To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. tp CJ. BY.{R.W. Bailey - Chief Engineer} S E C R E T. R8/M6.10.24. E.A.C.11. COMPRESSION RATIO. X.790. Since we have now got the EAC. engine so very smooth, I should favour another quarter on the compression so as to get the extra power that this would give. R.{Sir Henry Royce} | ||
