Military aeroplanes, simplified, enlarged; an explanatory consideration of their characteristics, performances, construction, maintenance, and operation, specifically arranged for the use of aviators and students . 5 ^ \. 79 No. 36, Eiffel is used on several military machines, and is a partic-ularly good wing for a medium speed, military scout. The Lift isnot run up very high, but the range of angles thru which a high L/Dis maintained is favorable, not only to high speed, but also to climb,as will later be explained, when consideration is given to the completeaeroplane as a unit. The Dorand wing, Eiffel No. 35, is similar to the Wright wing,and gives a very high lift, with a high L/D at angles from 3° to 6°.The small thickness of the section, however, does not make this wingvery favorable from the standpoint of construction. In general, thinnerwings are the more efficient, but spar room is a very necessary element,and efficiency and strength must be compromised. The Nieuport and Deperdussin are two standard wings, the lat-ter designed particularly for racing aeroplanes. R. A. F. 6 is one of the more modem sections that has been widelyused.
