| TO BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} Copy to - C.L. " RG.{Mr Rowledge} " HS.{Lord Ernest Hives - Chair} ORIGINAL E2/M2.3.26. 20HP. INDUCTION & EXHAUST PIPES WITH STRENGTHENED FLANGE. X5230 X5070 We thank you for your scheme No.735. which shews the above exactly as we asked for it. We have worked on the scheme and tried to introduce a few modifications with the following objects:- (1) To save weight and space by keeping the pipes closer to the cyl. block. (2) To provide a means of keeping the hot spot flange always clamped up so that no distortion of the pipes occurs when bolting up. (3) To straighten the exhaust downtake. (4) To straighten the exhaust manifold in plan. (5) To provide more clearance between the inlet pipe and the end exhaust joints for spanner room. We send herewith a blue print of LeC. 2206., shewing the scheme containing these further steps. We have also sent a blue print to R.{Sir Henry Royce} of this drawing, and told him that we propose to instruct it unless we hear from him to the contrary. We have also pointed out to him that item (2) could be applied to the flat type of joint for the hot spot flange if so desired. The only disadvantage of that can be seen on LeC. 2206. is that the slope of the inlet pipe is now reduced to about 1 1/2°, which is about the same slope as the transmission.
