Excerpt from The Triplane and the Stable Biplane

The following aerodynamical investigation was under taken to determine the suitability of the triplane arrange ment for weight-carrying as compared with the biplane. It appears that the triplane is not so effective as the biplane, and will require somewhat more power to drive; but with sufficient power the triplane can support nearly the same weight as the biplane at its attitude of maximum lift. The loss is only about per cent. At small angles near 4 deg, for the same lift the trip-lane requires some 6 per cent. More power than the corresponding biplane. At 4 deg. Incidence the ratio of lift to resistance is for the biplane against for the triplane.
