XXXVII D & ancAIRCRAFT ENGINEER OFFICIAL ORGAN OF THE ROYAL AERO CLUB WEIGH POWER RATIO REDUCED WEIGHT LB. PER B.H.P. AT MAX. R.P.M. AT I5,OOO FEET (AVERAGE OF LEADING BRITISH ENGINES ) S 4-4 Each reduction in the weight power ratio of aircraft engines results in greater demands being made on the steels which go to their construction. Every advance brings new problems for the metallurgist to solve and it is by constant research into these problems that Samuel Fox & Company have maintained their reputation as suppliers of aero engine steels. Improved designs and new fuels will make possible still further reductions in the weight per horse power and Fox steels will continue to contribute to the attainment of this desirable objective.
