REACTION DAMPERS. x7005. NEW PLATES AND OLD FABRICS. Why should new plates cause knocks if the old ones did not; it is hardly logical. E.{Mr Elliott - Chief Engineer} suggests water swollen fabric and spring screwed up choc-o-bloc to get sufficient friction. We can add 50% more area which one thinks would be good anyway. The design for this is sent to Derby by the same post as this memo. The spring must be suitable to the required pressure with fair rating and no limit collar. R.{Sir Henry Royce} | ||
