| To EFC. from R.{Sir Henry Royce} Copy to GS. ORIGINAL X.2981 RE APPARATUS FOR INDICATING PRESSURE IN HIGH SPEED ENGINES. RECEIVED 24 FEB 1921 I should be glad to know if any attempt has been made to prove the value of the scheme I suggested. We always desire to know the exact pressures existing during the various parts of the stroke of our engines, to enable us to make progressive improvements. When I next see you I will give you some further ideas on this subject, which are along the same lines, but another way of indicating the pressure by balancing it at different periods of the stroke.
