| -2- Rm{William Robotham - Chief Engineer}/Bd.{Mr Berend}13/VH. (2) Interference chamber. You will see from the above what the idea is. With regard to the noise side of the question, I do not know whether your scheme takes only power into account, or whether it is also supposed to effect a suitable degree of silencing. I should be very glad if you could give me some further dope on this. Now about the Phantom. I am afraid that obtaining cars for odd tests is not a very easy proceeding, and I am very much afraid that figures from this engine will have to wait until we get a unit on the bed. However, as soon as possible I'll let you have the figures you want. I'll drop you a line later and let you know how we get on. Yours sincerely, for ROLLS-ROYCE LTD. | ||
