Page 5 - Now there are only two ways of learning to ride a fractious horse: one is to get on him and learn by actual practice how each motion and trick may be best met; the other is to sit on a fence and watch the beast a while, and then retire to the house and at leisure figure out the best way of overcoming his jumps and kicks.
Page 46 - Having remarked how thin a stratum of air is displaced beneath the wings of a bird in rapid flight, it follows that in order to obtain the necessary length of plane for supporting heavy weights, the surfaces may be superposed, or placed in parallel rows, with an interval between them. A dozen pelicans may fly one above the other without mutual impediment, as if framed together ; and it is thus shown how two hundredweight may be supported in a transverse distance of only ten feet.
Page 21 - ... the rear till the angle of no lift is found. 4. That, with similar conditions, large surfaces may be controlled with not much greater difficulty than small ones, if the control is effected by manipulation of the surface themselves, rather than by a movement of the body of the operator.
Page 11 - In the 1900 machine one-fourth as much rudder action had been sufficient to give much better control. It was apparent that something was radically wrong, though we were for some time unable to locate the trouble.
Page 4 - The difficulties which obstruct the pathway to success in flyingmachine construction are of three general classes: (1) Those which relate to the construction of the sustaining wings; (-2) those which relate to the generation and application of the power required to drive the machine through the air; (8) those relating to the balancing and steering of the machine after it is actually in flight.
Page 15 - This time the velocity of the wind was 18 to 22 miles per hour. At first we felt some doubt as to the safety of attempting free flight in so strong a wind, with a machine of over 300 square feet, and a practice of less than five minutes spent in actual flight. But after several preliminary experiments we decided to try a glide. The control of the machine seemed so good that we then felt no apprehension in sailing boldly forth. And thereafter we made glide after glide, sometimes following the ground...
Page 13 - ... on account of this action on the upper side; but he seems never to have investigated the curvature and angle at which the phenomena entirely cease. My brother and I had never made any original investigation of the matter, but assumed that a curvature of one in twelve would be safe, as this was the curvature on which Lilienthal based his tables. However, to be on the safe side, instead of using the arc of a circle, we had made the curve of our machine very abrupt at the front, so as to expose...
Page 27 - ... slope, whenever the wind blew with sufficient force to furnish support, provided the wind were steady. But, by reason of changes in wind velocity, there is more support at times than is needed, while, at others, there is too little, so that a considerable degree of skill, experience, and sound judgment are required in order to keep the machine exactly in the rising current.
Page 11 - This was very encouraging, as it showed that one of the very greatest dangers in machines with horizontal tails had been overcome by the use of a front rudder. Several glides later the same experience was repeated with the same result. In the latter case the machine had even commenced to move backward, but was nevertheless brought safely to the ground in a horizontal position.
