Bailey - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} c. to Edy. Re. Bentley Shock Absorbers. Referring to Sg.{Arthur F. Sidgreaves - MD}7/F.13.3.34. Referring to the second paragraph of the above memo., on experimental cars we have run the 20/25 with controllable dampers for about 2 1/2 years. This is the car you had in France. We have run Peregrine - the car completed 15,000 miles satisfactorily in France with controllable dampers. These two cars had controls made up with rods and joints. In addition to these we have J.111 which has the Aerons type of control and which has run 16,000 miles. It is because we have had perfectly satisfactory results over prolonged running with various forms of shock absorber control including, of course, the R.R. hydraulic scheme, that we think to Standardise the scheme which we are now running would be a retrograde step. on the Bentley Hs.{Lord Ernest Hives - Chair} | ||
