X.3436 To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to BJ. BY.{R.W. Bailey - Chief Engineer} EP.{G. Eric Platford - Chief Quality Engineer} R3/M8.10.24. RE. EXHAUST NOISE ON 40/50 HP. X.3436. With regard to BJ1/H1.10.24., before doing anything further to the design as it now stands, such as lagging the pipe, I think we ought to try and find the source of the noise. It may be due to some change in diameter, or some sharp feature on the internal form of the exhaust system. R.{Sir Henry Royce} | ||
