Description
Gliding flight is a comparatively new field for the amateur to delve in, but the time has arrived when it is being extensively taken up both as a sport and a means of experiment.
Many very costly aeroplanes have failed to fly because of man’s total inexperience in the art of flying. All of the great aviators now before the world, whose machines are the result of their own genius learned to fly before succeeding in a motor driven machine.
The Wright brothers spent no less than three years on the sand dunes near the coast of North Carolina making gliding flights. They approached the difficulties in a methodical manner, working out each problem and determining which was the best means of accomplishing a certain result.
To control the tendency to pitching, they devised an elevation rudder and attached it to the front of their machine. The next step was to determine whether equilibrium should be maintained by shifting the centre of gravity or if there was not a better method and they introduced what is probably the most valuable feature of the modern aeroplane, namely the warping or twisting of the ends of the planes to secure lateral stability when a gust of wind strikes one end of the machine.
In this manner the Wright’s continued their experiments until every move had become a matter of habit and to balance and guide an aeroplane was almost an instinct.
A gasoline engine was then fastened in the machine and connected to drive two screw propellers at the rear. Dec. 17, 1903 the machine flew for a few seconds.
The leaps and bounds with which aviation has since progressed both in the hands of the Wrights and others is a matter too well known to be repeated.
There is therefore no excuse necessary to be made for this little book, coming as it does at this time and it is sincerely hoped that it may interest and lead many to experiment first and build their aeroplane afterward so that when their machine is complete it may be practical and not intended to operate in some "lift-yourself-by-your-boot-straps" manner.
