If the Taring is tapered sufficiently, the spars can be brought together at the tips as in the German Ago, simplifying and increasing the rigidity of the drag truss. . Figure 24.… … the L/D is plotted against t^c ^ ^ evident that the constant section wing is inferior in efficiency at every point. There was time for only a very limited study of this subject, but the results show enough promise to deserve further investigation.
