| x3461b To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} Copy to CJ. " " Bn.{W.O. Bentley / Mr Barrington} " " Da.{Bernard Day - Chassis Design} " " By.{R.W. Bailey - Chief Engineer} " " EFC. R7/G22.6.20. X.3461b. RE SHOCK DAMPERS. X.2628b. With reference to your report Hsl/AT18.6.20, do the shock dampers loose their gease, or does it simply work from between the plates ? Does it suggest more plates and possibly smaller steps between them ? I think we ought to arrange the working condition to be 20 lbs. What is the percentage of friction in the front and rer springs themselves ? Perhaps these shock dampers do proportionately too little to justify their existence, yet we understand the result of road test shewd that they make definite improvement. R.{Sir Henry Royce} | ||
