| From R.{Sir Henry Royce} (At Le CanadelHenry Royce's French residence.) [Text crossed out] C. to [Text crossed out] R1/M9.3.32. Sent from TM. 12.3.32. Many thanks for your very interesting memo. of your visits to 'plane makers, etc. Re. Mr. Bruce's (Westland) scheme of long propeller shaft one rather fears the torsional elasticity of this, especially with two blades. The Bristol compression ignition unit one thinks would probably be a poppet valve engine, although we heard from Ricardo that the sleeve valve was doing well with them. I am also very pleased that you can make header tanks that do not lose water except as steam. The valve and slight pressure scheme we put in cars is a very definite improvement. Much of the water was lost by mechanical motion due to road conditions, and corners. R.{Sir Henry Royce} | ||
