| X319 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Std.5/KW 20.10.36. Phantom III Cylinder Head Water Flow. We consider that we can reduce the tendency to local hot-spots, steam pockets, etc., by making the water flow longitudinally; i.e., from the back of the head to the front. We also wish to test out on the test bed the effect on water flow of the deletion of some of the water holes which is now standard production. Will you therefore build up a Ph.III unit (Hs{Lord Ernest Hives - Chair}/Swdl.{Len H. Swindell} will indicate which one) with the two cylinder heads which are fitted with the Rm.{William Robotham - Chief Engineer}199 outlet scheme and which have just been removed from No.8 unit. Before these are fitted, will you please block up the water holes which are now deleted on the standard Ph.III heads, thus making the heads standard in this respect. Will you also have the necessary piping etc. made to connect the oil temperature regulator box to the rear of each cylinder head: this is only a test rig-up and we do not require any parts detailing. We shall run the longitudinal water flow test by removing the oil cooler matrix and taking the water flow direct from the box to the rear of the cylinder head. The attached sketch shows what is required. Hs{Lord Ernest Hives - Chair}/C.S.Steadman. | ||
