| TO HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} Copy to BJ. Copy to BY.{R.W. Bailey - Chief Engineer} Copy to EP.{G. Eric Platford - Chief Quality Engineer} re. EXHAUST NOISE ON 40/50. K.{Mr Kilner} 3436 With regard to BJ1/H11024., 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} | ||
