A.A.—Main-planes; B. Double front elevator; C. Rudder (two narrow vertical planes); D. Motor; E. Propellers; F. Pilot’s lever; G. Skids upon which machine landed. It is now possible to describe, as a completed craft, the Wright power-driven plane; The picture shows its appearance; and in looking at it one is struck by the fact that, save for one or two modifications, and the fitting of motor and propellers, the machine is practically a glider, such as the Wrights used for soaring tests. Of the changes to be observed, the most interesting concern the elevator and rear-rudder. The former, it will be seen, has a double plane; it is, in fact, a smaller biplane on the principle of the main-planes. Needing to increase the surface of the elevator, the brothers fixed one plane above another so as to make the construction stronger and occupy less space. The rear-rudder, acting like that of a ship. - The Wright Wing-warp
Apart from governing the ascending or descending movement, there was the question of preventing a machine from slipping sideways; and this the Wrights solved ingeniously. They saw, of course, that when their glider lurched to one side or the other, they would need some power to tilt it back again. So they devised a system by which the plane-ends of their machine—being made flexible—might be warped, or caused to shift up and down. This action the operator controlled, as he lay across the lower plane, by a movement of cords, and its operation is shown in Figure. The effect upon the machine may be described thus: should a wind-gust tilt down one plane-end, the “warp” upon that side of the machine was drawn down also, and the effect of this—seeing that it caused the plane to assume a steeper angle to the air and exercise a greater lift—was to raise the plane-ends that had been driven down by the gust. By a system of connecting the control cords, this balancing influence was made to act with double force; when one wing warped down, the other moved up; and, in this way, while the side of the machine tilted down was made to rise, the other plane-ends, which had been lifted, were made to descend. A dual righting influence was thus obtained. This system, which imitates the flexing movements made by a bird, was an important device; the Wrights patented it—combining the movement with an action of the rudder—and brought cases at law to enforce their rights. - Thoth
When the land was divided into separate estates or properties, Thoth, the Pillar or Landmark at the corner of the field, became an important god; and as the owner's name was carved upon it, he was the god of letters and of all learning. - Three-decked ship of the line, 18th century

A form of glider, mounted upon hollow wooden floats—anticipating the sea-plane of to-day—and towed upon the river Seine by a motor-boat. This gilder also, when its speed became sufficient, rose into the air. In the construction of the machine, a biplane, one notes resemblances to the method of the Wrights; and yet generally the craft is dissimilar. - Voisin Glider towed by a motor-car
In the launching of gliders, some French experimenters showed ingenuity. The brothers Voisin, for instance, who played a prominent part in the early tests in France, adopted the plan illustrated. The gilder was towed by a motor-car across an open stretch of ground; then, when its speed was sufficient for the planes to lift, it rose and flew behind the car like a kite. - Wings
Wings - Wright Launching Rail
A. Biplane; B. Rail; C. Rope passing from the aeroplane round the pulley-wheel (D.) and thence to the derrick (E.); (F.) Falling weight. Details of propulsion and control being arranged, there remained the question of how the machine should be launched into the air. In their gliding tests, it will be remembered, the Wrights employed assistants, who held the machine by the wing-tips and ran forward with it. But the weight of the power-driven machine, and its greater size, prevented such a plan as this. They decided, therefore, to launch it from a rail, and to aid its forward speed, at the moment of taking the air, by a derrick and a falling weight. - Wright Motor and Propellers
When the Wrights had built an engine, there was still the question how they should make it drive their aeroplane. They inclined naturally to the idea of an aerial propeller. Two courses lay open to them; they could fit one propeller running at high speed and coupled directly to the motor, or they could use two propellers, revolving at slower speed and geared in some way to the engine. They decided upon the latter course, placing two propellers behind the main planes of their machine and driving them from the engine by means of light chains, these running in guiding tubes. This system of propulsion is shown. A. Motor; B. Gear-wheels upon motor crank-shaft; C.C. Tubes carrying driving chains; D.D. Sprocket-wheels over which chains pass; E.E. Propellers. - Yale 1910
