Mr. Bigelow. Dear Sir:鈥擨 write to let you know how I am getting along. Hard times here. I have not had one hour to go outside the place since I have been on it. I put my trust in the Lord to help me. I long to hear from you all I written to hear from you all. Mr. Bigelow, I hope you will not forget me. You know it was not my fault that I am here. I hope you will name me to Mr. Geden, Mr. Chaplin, Mr. Bailey, to help me out of it. I believe that if they would make the least move to it that it could be done. I long to hear from my family how they are getting along. You will please to write to me just to let me know how they are getting along. You can write to me. The next notable event was Paulhan鈥檚 London-Manchester flight, of which full details have already been given. In May Captain Bertram Dickson, flying at the Tours meeting, beat all the Continental fliers whom he encountered, including Chavez, the Peruvian, who later made the first crossing of the Alps. Dickson was the first British winner of international aviation prizes. 北京pk10单吊计划 Follows Professor John J. Montgomery, who, in the true American spirit, describes his own experiments so well that nobody can possibly do it better. His account of his work was given first of all in the American Journal, Aeronautics, in January, 1909, and thence transcribed in the English paper of the same name in May, 1910, and that account is here copied word for word. It may, however, be noted first that as far back as 1860, when Montgomery was only a boy, he was attracted to the study of aeronautical problems, and in 1883 he built his first machine, which was of116 the flapping-wing ornithopter type, and which showed its designer, with only one experiment, that he must design some other form of machine if he wished to attain to a successful flight. Chanute details how, in 1884 and 1885, Montgomery built three gliders, demonstrating the value of curved surfaces. With the first of these gliders Montgomery copied the wing of a seagull; with the second he proved that a flat surface was virtually useless, and with the third he pivoted his wings as in the Antoinette type of power-propelled aeroplane, proving to his own satisfaction that success lay in this direction. His own account of the gliding flights carried out under his direction is here set forth, being the best description of his work that can be obtained:鈥? They will not come to-night!鈥攎y sinking heart Yet his conclusions on this point were not altogether negative, for as early as 1810 he stated that he could construct a balloon which could travel with passengers at 20 miles an hour鈥攈e was one of the first to consider the possibilities of applying power to a balloon. Nearly thirty years later鈥攊n 1837鈥攈e made the first attempt at establishing an aeronautical society, but at that time the power-driven plane was regarded by the great majority as an absurd dream of more or less mad inventors, while ballooning ranked on about the same45 level as tight-rope walking, being considered an adjunct to fairs and f锚tes, more a pastime than a study. 鈥?. That the ratio of drift to lift in well-shaped165 surfaces is less at angles of incidence of 5 degrees to 12 degrees than at an angle of 3 degrees. He resumed his walk along the river bank, speaking aloud, and gesticulating to himself as he went. Probably wakened to realisation of the possibilities of the aeroplane by the Rheims Meeting, Germany turned out its first plane late in 1909. It was known as the Grade monoplane, and was a blend of the Bleriot and Santos-Dumont machines, with a tail suggestive of the Antoinette type. The main frame took the form of a single steel tube, at the forward end of which was rigged a triangular arrangement carrying the pilot鈥檚 seat and the landing wheels underneath, with the wing warping wires and stays above. The sweep of the wings was rather similar to the later Taube design, though the sweep back was not so pronounced, and the machine was driven by a four-cylinder, 20 horse-power, air-cooled engine which drove a two-bladed tractor propeller. In spite of Lilienthal鈥檚 pioneer work years before, this was the first power-driven German plane which actually flew. Hargrave, to diverge for a brief while from the machine to the man, was one who, although he achieved nothing worthy of special remark, contributed a great deal of painstaking work to the science of flight. He made a series of experiments with man-lifting kites in addition to making a study of flapping-wing flight. It cannot be said that he set forth any new principle; his work was mainly imitative, but at the same time by developing ideas originated in great measure by others he helped toward the solution of the problem.
