The Early History of the Airplane

Orville and Wilbur Wright

Book Overview: 

The Brothers Orville and Wilbur Wright made the first controlled, powered and sustained heavier-than-air flight, on 17th December 1903. They were not the first to build and fly aircraft, but they invented the controls that were necessary for a pilot to steer the aircraft, which made fixed wing powered flight possible. The Early History of the Airplane consists of three short essays about the beginnings of human flight. The second essay retells the first flight: "This flight lasted only 12 seconds, but it was nevertheless the first in the history of the world in which a machine carrying a man had raised itself by its own power into the air in full flight, had sailed forward without reduction of speed and had finally landed at a point as high as that from which it started."

Book Excerpt: 
. . .Aeronautical Society of Great Britain made similar experiments. Many persons likewise published measurements and formulas; but the results were so discordant that Professor Langley undertook a new series of measurements, the results of which form the basis of his celebrated work, “Experiments in Aerodynamics.” Yet a critical examination of the data upon which he based his conclusions as to the pressures at small angles shows results so various as to make many of his conclusions little better than guesswork.

To work intelligently, one needs to know the effects of a multitude of variations that could be incorporated in the surfaces of flying machines. The pressures on squares are different from those on rectangles, circles, triangles, or ellipses; arched surfaces differ from planes, and vary among themselves according to the depth of curvature; true arcs differ from parabolas, and the latter differ among themselves; thick surfaces differ from thin, and. . . Read More
