Eric Platford - Chief Quality Engineer} Lp.{Mr Lappin} C. FV. F.{Mr Friese} C. Mr. Jaques. RE: THERMOSTATIC SHUTTERS With regard to Hs{Lord Ernest Hives - Chair}/Hkr.{Mr Harker - RAF liaison pilot}3/1/U29.7.33, from the information given it would appear that the shutters are open for 10% of their movement in the closed position. This is presumably due to the setting of the levers and will make quite a difference to the temperature control. It will, in fact, have a big influence throughout the whole range. Would Hs{Lord Ernest Hives - Chair}/Hkr.{Mr Harker - RAF liaison pilot} please take this up with Farnborough. From the work that has been done I think it can be said that the thermostatic shutters can now be applied successfully to any type of water cooled engine having radiators. LR.{Mr Ellor} | ||
