N.A.C.A.* Technical Memorandum No,502 Figs.20 & 21 M/q Aerodynainic moment Fig.20 U7 Pitching moments and inertia forces. The aero- dynamic pitching moment is almost twice.as great as for the U6,which has aamost the came wing and tail. On referring to Fig.18,it is seen that the square of the… … moment Fig,21 U12 Pitching moments and inertia forces. The magni- tude of the aerodynamdc pitching moment is conspic- uous. The airplane was equipped and spun-with a larger ele- vator than that used in the wind-tunnel tests. In practice therfore the pitching moment is still greater. The airplane…
