Meteorological Investigations in Free Air at Blue Hill Observatory. Milton, Mass. A. L. Kotch. Set of Typewritten Articles. PROPELLERS AND MOTORS. To the Editor of FLIGHT. SIR,—Referring to Mr. Montford Kay's letter in last week's issue, I really must protest against the notion expressed by him— and too prevalent elsewhere—that the type or the proportions of a properly-designed aerial propeller are necessarily varied when applied to different aeroplanes. Many years' devotion to aerodynamic experimenting and specialising on propellers has convinced me that the propeller that is most efficient for one aeroplane is most efficient for all machines of this class ; the size of propeller, of course, being varied to suit a larger or a smaller machine. I am now, of course, dealing only with horizontally-acting fans, used either as propellers or tractors, excluding the helicoptere or vertical lifting-screw systems, and also "gas-bags" (believing in neither). Mr. Montford Kay says, too, that it is " a safe thing " to criticise other productions away from a testing platform. -(I presume that adversely is meant ?) To that I will say, it would be by no means " a safe thing" if the adverse criticism should be groundless. It would then be open to those concerned to dispute or to disprove it. As Mr. Kay obviously wrote with special reference to my strictures on the " Voisin " propeller, I will remind him that, as I said, " it is notorious that over 50 per cent, of the power applied is wasted by that propeller, i.e., it is a fact only too well known (but apparently not widely enough yet)." Let me add that my propeller has creditably passed the ordeal of " the testing platform." I agree with Mr. Montford Kay that " the proof of the pudding is in the eating thereof." Well, my particular confection has proved highly palatable, though given to " rising."
