| LFS x 122. To R.{Sir Henry Royce} from E.{Mr Elliott - Chief Engineer} E.13/HP.12.11.32. c. Sg.{Arthur F. Sidgreaves - MD} For. Hs.{Lord Ernest Hives - Chair} Hvy re Peregrine 2 Engine Suspension. Please find herewith Lec.3266 and Lec.3270 showing proposed front engine mounting for Peregrine on the assumption that only a small amount of friction will be required for torque reaction damping. Hancock's car in France is equipped with both types of dampers, that is, some damping on the front suspension of the engine, which can be slacked off if desired, and also some dampers of our standard type directly attached between frame and crankchamber. He is proceeding to make experiments to determine utility of both types. With regard to the diagonal tie rods locating the engine endways, we attach herewith a blueprint of Lec.3247 showing these in conjunction with the dampers carried direct on the crankcase. We hope and expect to avoid dampers of this type, and as regards the diagonal rods we feel now that the transmission has altered, and that the axle is no longer able to pull and push at the engine, that perhaps the method of locating the engine endways, shown in Lec.3266 and Lec.3270 is all that is necessary, particularly as the latter method would be required if we adopted the proposed scheme of front crossmember where the members of the crossmember assembly should be kept together as a unit.
