| P.2. RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KT.26.10.32. PEREGRINE FRONT ENGINE MOUNTING. We have now decided that certain modifications are necessary to the engine mounting fitted to 2.Per.II as a result of our experience on Hs.{Lord Ernest Hives - Chair}709. These are shown on the attached sketch Hs.{Lord Ernest Hives - Chair}740. The major differences are :- (1) The central mounting has been altered so that the fan belt can be fitted and a ferobestos bush incorporated. (2) We have increased the quantity of rubber controlling the torsional movement of the engine, and made it easily demountable as a unit. (3) We show the longitudinal stiffness cut away so that there is more clearance for the fan belt. One undesirable feature of this engine mounting is that the radiator brackets have to be off-set. It will be remembered that the original design called for this state of affairs but was overcome by modification to the bottom tank. If this engine mounting proves successful, this modification will be made. We want to get this engine mounting on the first car going to France as it will give us an opportunity of testing the torque reaction dampers in the front engine mounting, and at the same time those directly from the crankcase to the frame. The result of these tests will enable modifications to be made to LeC.3241. It will be noted that the main crossmember has not been altered in Hs.{Lord Ernest Hives - Chair}740. We should like two sets of parts made, one for the Bumper Chassis, and one for 2.Per.II for France next week. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
