I think that we should certainly try Da {Bernard Day - Chassis Design} /Hdy {William Hardy} 's proposal of a kinetic energy restriction on the damper control for Bentley V. {VIENNA} rather than introduce bimetallic controls. The kinetic energy restriction,if satisfactory, has nothing to get out of order, and personally I wish to have this tried out as the scheme most likely to give us trouble free working. In regard to priming of the pump, I should not have anticipated from my experience that a regular priming leak would be necessary, as once the pump has been filled with oil it would remain oily enough to charge itself. In the case of petrol pumps on aero engines, these would lift 12 ft. and unless they have been standing for a long time require no priming. BY. {R.W. Bailey - Chief Engineer} BY | ||
