Average Weight Per Horse Power.
It will be noticed that the Gnome motor is unusually
light, being about three pounds to the horse power
produced, as opposed to an average of 4 1/2 pounds per
horse power in other makes. This result is secured by
the elimination of the fly-wheel, the engine itself revolving,
thus obtaining the same effect that would be produced
by a fly-wheel. The Farcot is even lighter, being
considerably less than three pounds per horse power,
which is the nearest approach to the long-sought engine
equipment that will make possible a complete flying
machine the total weight of which will not exceed one
pound per square foot of area.
