| X8010 Hs{Lord Ernest Hives - Chair}/Tsn2/T. 29th February, 1928. X5010 X634 Major B.C. Carter, R.A.E., Farnborough. Dear Sir, We attach the results of our work on Crankshaft Torsional Vibrations. As you will see, the basis all through has been your very useful formula for predicting the torsional stiffness. It appears to be amazingly accurate for such a simple expression, and we are very grateful for your assistance in this matter. We shall from time to time send you information as it accumulates. We regret that our work has so far been confined to car engines, but we can promise you some aero results in the near future. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
