Kite flying

“ Scientific kite-flying was one of the keenest pleasures of these three particular Hill-dwellers, and six or eight kites strung out on a mile of twine and soaring into the clouds was an ordinary achievement for them. They were compelled to replenish their kite-supply often; for whenever an accident occurred, and the string broke, or a ducking kite dragged down the rest, or the wind suddenly died out, their kites fell into the Pit, from which place they were unrecoverable. ”

“ The kite flying side will not help so much as the gliding. When the aeroplane kite is well up, if the string is allowed considerable slack, the model will glide if well balanced and if the planes are tilted properly. Balance will be necessary both to right and left and fore and aft. It is very interesting to get such a model pulled well up in the air and have a release that will cut the kite line. The punk method is good, only that we would like to have better control of just the time for cutting loose. ”

“ Occasionally opponents try to capture an enemy’s kite. Competitive kite-flying is accomplished by covering the first ten or twenty feet of the kite string with fish glue or rice paste, and then dipping it into pounded glass or porcelain. ”

“ Kite-flying is a national institution here as in China and Japan. The kites are not so elaborate as in the neighbouring countries, but the interest in the sport is fully as great, for there are what may be called kite-fights that are very exciting. By dextrous manipulation the rival kite-fliers get their strings crossed. ”

“ There is only one way to learn the practical art of kite-flying, and that is to begin and do the thing yourself—with many mishaps and disappointments at the outset. One of Mr. Eddy's practices when sending kites up in very light winds or in an apparent calm, is to reel out two hundred yards or so of cord in a convenient open space, leaving kite and cord on the ground until ready to start. Then, by taking the cord at the extreme distance from the kite, and beginning to run with it, he gets it quickly into the upper air currents, which are always stirring more than those at the surface. ”

“ The process of kite-flying is as follows. The first kite is started either with the self-recording instruments secured in it, or hanging from the wire a short distance below it. Wire is then paid out, whether quickly or slowly depends on the strength of the wind, but the usual rate is from two to three miles per hour. The quantity that one kite will take depends on the kite and on the wind, but roughly speaking it may be said that each 10 sq. ft. of lifting surface on the kite should carry 1000 ft. ”

“ We cannot, however, as we watch, say, a hawk, hovering in the air with motionless wing, help being struck by its resemblance to the schoolboy’s kite, kept afloat high in the sky by the action of the wind properly applied to its surface, and we can at once see that the bird makes use of the same principle as the kite in its soaring or hovering flight. Indeed, just as a kite sinks to earth when the wind drops, so in a dead calm even an albatross has to flap its wings to keep afloat.
It is to the principle of the kite, therefore, that the inventor of the flying machine must turn. ”

“ This is one of the most interesting discoveries in kite flying, though badly upset in actual practice, when one member of the team becomes erratic and proceeds to make a braid of the four cords by diving under and over the others to bring about a general demoralization. For this reason, it is wise to test each kite separately, first, to discover any possible tendency to freakishness. ”

“ Kite flying is such fascinating sport that the three typical kites here given will make one want to build others, larger and of different shapes. [2] Kites have been made large enough to carry a man high in the air. The adjustments of a kite are so subtle that much patience is sometimes needed to make it fly. That is why the rather elaborate bridle is suggested for the paper covered kite with tail. ”

“ Kite-flying has always been a national pastime of the Koreans, Chinese, Japanese, Tonkinese, Annamese, Malays and East Indians. It is less popular among the peoples of Europe. The origin of the sport, although obscure, is usually ascribed to religion. With the Maoris it still retains a distinctly religious character, and the ascent of the kite is accompanied by a chant called the kite-song. ”

“ Many attempts have been made to turn kite-flying to practical uses, but with scarcely any other result than to shew that in the art of kite-flying we are far behind China and Japan. Success depends on the shape of the kite; and if a kite{64} presents a flat surface to the wind, it will be unsteady, and cannot be employed in a successful experiment. ”

“ As soon as the wind has fairly caught the kite and carried it up into the air, the boy who holds the string need run no longer, but if the breeze suddenly fails, and the kite begins to drop, he may still keep his toy aloft by running quickly along and dragging the kite after him; the artificial wind he thus creates making up for the lack of the other. ”

“ In a high wind a large kite is used in place of a captive balloon. It is a box-kite made of bamboo and carries a passenger in a car, the car running on the cable which attaches the kite to the ground. Now suppose a kite with a motor and pro [186] peller in place of a string and a boy to run with it, and that the kite is able to balance itself, then it will sail against a wind of its own making and you have a flying-machine heavier than air.
The first aeroplane that would fly under perfect control of the operator was built by the Wright brothers at Dayton, Ohio. ”

“ When starting a kite you need the help of some one who will stand about thirty yards away, holding the kite against the wind, and throw it straight up when you have the line tight and give the signal. If it does not rise it may be well for you to run a few yards against the wind. At first you must not pay out line very rapidly, but when the kite is flying steadily you may give it, also steadily, all the string it wants. ”

“ Men may often be seen on calm still days flying their kites from boats as they pass up and down the river. Kite contests are of frequent occurrence during the windy months. One kite is called the male and the other the female. The object of the contest is the capturing of the female by the male. [Pg 153] When they are both at a considerable height from the ground, one flyer so jerks the string of the male kite as to cause it to swoop downwards with great velocity. If the apex of the falling star strikes the body of the soaring female, it effectually wounds her and brings her to earth. ”

“ If two boys attempt to fly a kite in a calm, the one must hold up the kite and let go when the other runs. In this case the under surface of the kite is made to strike the still air. If, however, a stiff autumn breeze be blowing, it suffices if the boy who formerly ran when the kite was let go stands still. In this case the air in rapid motion strikes the under surface of the kite and forces it up. ”

“ The string of a kite is so adjusted that as the kite rises it is still held at an angle to the wind’s force, and so long as the kite remains tilted at the necessary angle so long it will continue to rise or poise itself in the air while the wind blows. When schoolboys fly their kites they110 choose an exposed spot, and a day when the wind is blowing freshly and steadily. One boy throws the kite into the air, while another, holding the string to which it is fastened, draws it tight by running with it against the wind. ”

“ Where the Kite formed by the Wing differs from the Boy’s Kite.—The natural kite formed by the wing differs from the artificial kite only in this, that the former is capable of being moved in all its parts, and is more or less flexible and elastic, the latter being comparatively rigid. ”

“ The making of kites has now reached a high pitch of perfection, and by their means self-recording scientific instruments can be raised to vast heights in the air, and even men carried aloft with safety. A kite which latterly has excited much attention is the Cody kite. With this, during the autumn of 1903, its inventor, a Mexican, hazarded a bold venture.124 Harnessing it to a light boat, and waiting for a favourable wind, he started from Calais at eight o’clock one November evening, and was safely towed all night across the Channel, reaching Dover at five the next morning. ”

“ The lower strand was made elastic by tying it fast to a number of heavy rubber bands, as in Fig. 242. When flying the kite, if a sudden, strong puff of wind struck it, the elastic belly band would give, tilting up the lower end of the kite so that the wind passed under; but as soon as the gust had passed the rubber bands would draw the lower end of the kite back against the wind. The elastic belly band had the effect of making the kite rise almost vertically. Sometimes it would even sail square overhead. The 8-foot kite was a very powerful one. ”

“ If a little variety in outline is desired, split bamboo or reed could be used to make such forms as are desired; even string connections can be made.
In making hollow form objects both patience and skill are necessary. A form that is interesting but not representative of any real object is shown in Fig. 99. Another is the arrow kite, Fig. 100. The flying bird kite should make a good problem for some ingenious chap. The framework and stringing is shown in Fig. 101. The cross-section of the body of the bird is about the shape of a tailless kite. ”

“ The original Hargrave kite, the form generally used, has a rectangular section; in Russia a semicircular section with the curved part facing the wind is most in favour; in England the diamond-shaped section is preferred for meteorological purposes owing to its simplicity of construction. Stability depends on a multitude of small details of construction, and long practice and experience are required to make a really good kite. ”

“ The boys in the streets of Buenos Ayres are as saucy a set of ragamuffins as those of London, without that daring and instant battle of the English boys. Many of their juvenile sports are similar to our’s; as kite flying, pitch in the hole, &c. They have a system of managing their kites, which may be called privateering: a knife is affixed to the- 125 - tail of the kite, with which they endeavour to entangle other kites, and cut the string; should they succeed, knife, kite, string—all become lawful prize. Cricket, trap-ball, hoops, tops, and skipping, they do not practise. ”

“ Kite-fighting is a feature of the pastime in Eastern Asia. The cord near the kite is usually stiffened with a mixture of glue and crushed glass or porcelain. The kite-flyer manœuvres to get his kite to windward of that of his adversary, then allows his cord to drift against his enemy’s, and by a sudden jerk to cut it through and bring its kite to grief. The Malays possess a large variety of kites, mostly without tails. ”

“ When it is known that a box kite having only sixty square feet of sustaining surface, flying at a considerable height, may lift a person of ordinary size, one is impressed with the idea that vessels of commerce might employ kites of large dimensions to increase the speed of sailing ships. The kites would fly in a stratum whose velocity is not restricted by friction with the surface of the water. ”

“ All have superposed aeroplanes [viii] of great length from port to starboard, all have fore and aft horizontal rudders, and all are driven with screw propellers. The change from my model is only a change in the framework made possible by dispensing with the boiler, water tank, and steam engine. In this little work, I have dealt at considerable length with air currents, the flight of birds, and the behaviour of kites, perhaps at the expense of some repetitions; as the resemblance between kite flying and the soaring of birds is similar in many respects, repetitions are necessary. ”

“ Another way of flying kites in tandem is to fasten all kites directly to the one kite line, the line passing thru each kite after the first. This method however requires a helper for each kite and they are placed closer together. At one of the Los Angeles Tournaments, two boys had a beautiful team of green and white kites arranged in the second series of tandem. ”

“ One interesting outcome of his numerous experiments was the Hargrave Kite, now more familiarly191 known as the box kite. A good example of his kites is the type shown in Fig. 35. This consists of two arched biplanes mounted tandem on a backbone, or connecting framework. The kite floats steadily, and was thought suitable for the body of a flying machine to be driven by an engine and propeller. Thus meteorology is indebted to aëronautics for its most useful kite. ”

“ The soaring bird, Fig. 102, is quite similar in construction to the preceding kite. The body is never square in cross-section. A little bow is given to the tip ends of the wings. The back line of the wing changes by means of an extra cord. This kite is not as stable as “The flying Bird.”

The “flying fish,” Fig. 103, needs vents, as the whole body is a box-kite. Two views of the framework are given; a center spine runs the entire length of the fish with two curves at the mouth. The mouth is left open, so string is used for the outline. ”
