Letting the heated air escape, firstly by louvred bonnet: and keeping up the speed, (engine revs.) is the chief difference in our case and Hispano. (15) E.{Mr Elliott - Chief Engineer} suggests an increase of some other change in the water circulation to reduce steam pockets. It can be tested if this is advantageous, because after the quantity of water is thrown out due to expansion etc. is the water in the top of the tank at boiling temp. If not, then improvement would be helpful. R.{Sir Henry Royce} | ||
