Military aeroplanes, simplified, enlarged; an explanatory consideration of their characteristics, performances, construction, maintenance, and operation, specifically arranged for the use of aviators and students . le type of mainsurface and tail aeroplane, so widely and successfully used. The Taube The outstanding feature of this old type, a German pigeon shapemonoplane, is a retreating wing shape combined with upturned wingtips of flexible construction. The upturned wing tips, when warpedfor lateral control, give a distinctly greater resistance on the side thatit is desired to lower, thus helping to turn the machine properly whenbanked. This, combined with the retreat, does give a strong, in-herent stability action, tending to eliminate side-slipping and skid-ding very much as on the Dunne, but the Taube has rudders whichpermit of powerful control, near the ground. The flexible, upturnedwing-tip feature, renders the c. p. movement for the wing favorableto longitudinal stability by increased negative pressure at the rear 170 of the wing when the incidence is decreased, and reduction of thispressure when it is increased. This feature, however, is wasteful of power and slow acting on A Taube in flight. The up-turned wing tips are evident. Above — A modern Taube.—The flexing of the wingend is indicated; below a more modern Aviatik. Summary There may be drawn from the consideration of the common ele-vator rudder and laterally controlled main and tail surface aero-planes, several interesting conclusions on airworthiness. The most airworthy combination for longitudinal control andstability would appear to be a slightly negative tail on a convergenttandem system of which the flaps form a large percentage of the area,so that ample control is obtained with minimum effort and drag. On the lateral equilibritun, handy control, wind-fighting qualities,natural stability and comfort, seem best obtained by a combination ofpowerful lateral controls, on an aeroplan
