"Kennedy," he exclaimed, unable to restrain himself longer, pushing aside Doctor Lathrop, as he placed himself between her and the man whom he regarded now as her tormentor, "Kennedy鈥攜ou are a faker鈥攏othing but a damned dream doctor鈥攊n scientific disguise." pk10定位胆6码技巧稳赚 Christ Church, Woking. Minnie joined her hands together on the table, and thus supported, she leant a little forward, and looked searchingly at the young man. The presentation of the prize to Paulhan was made the occasion for the announcement of a further competition, consisting of a 1,000 mile flight round a part of Great Britain. In this, nineteen competitors started, and only four finished; the end of the race was a great fight between Beaumont and Vedrines, both of whom scorned weather conditions in their determination to win. Beaumont made the distance in a flying time of 22 hours 28 minutes 19 seconds, and Vedrines covered the journey in a little over 23? hours. Valentine came third on a Deperdussin monoplane and S. F. Cody on his Cathedral biplane was fourth. This was in 1911, and by that time heavier-than-air flight had so far advanced that some pilots had had war experience in the Italian campaign in Tripoli, while long cross-country flights were an everyday event, and bad weather no longer counted. About Dorrington? Oh, before Christmas. I should say by the end of the first week in December. Diamond will be a loss to me, but I shall be glad of his promotion. He's a gentleman, and a very good fellow, although his manner is a trifle self-opiniated. And, added the doctor, shaking his head and lowering his voice as one does who is forced to admit a painful truth, "I am sorry to say that his views as to the use of the Digamma are by no means sound." Volume III CHAPTER I. Up to this point an attempt has been made to give some idea of the progress that was made during the eleven years that had elapsed since the days of the Wrights鈥?first flights. Much advance had been made and aeroplanes had settled down, superficially at any rate, into more or less standardised forms in three main types鈥攖ractor monoplanes, tractor biplanes, and pusher biplanes. Through the application of the results of experiments with models in wind tunnels to full-scale machines, considerable improvements had been made in the design of wing sections, which had greatly increased the efficiency of aeroplanes by raising the amount of 鈥榣ift鈥?obtained from the wing compared with the 鈥榙rag鈥?(or resistance to forward motion) which the same wing would cause. In the same way the shape of bodies, interplane struts, etc., had been improved to be of better stream-line shape, for the further reduction of resistance; while the problems of stability were beginning to be tolerably well understood. Records (for what they are worth) stood at 21,000 feet as far as height was concerned, 126 miles per hour for speed, and 24 hours duration. That there was considerable room for development is, however, evidenced by a statement made by the late B. C. Hucks (the famous pilot) in the course of an address delivered before the Royal Aeronautical Society307 in July, 1914. 鈥業 consider,鈥?he said, 鈥榯hat the present day standard of flying is due far more to the improvement in piloting than to the improvement in machines.... I consider those (early 1914) machines are only slight improvements on the machines of three years ago, and yet they are put through evolutions which, at that time, were not even dreamed of. I can take a good example of the way improvement in piloting has outdistanced improvement in machines鈥攊n the case of myself, my 鈥榣ooping鈥?Bl茅riot. Most of you know that there is very little difference between that machine and the 50 horse-power Bl茅riot of three years ago.鈥?This statement was, of course, to some extent an exaggeration and was by no means agreed with by designers, but there was at the same time a germ of truth in it. There is at any rate little doubt that the theory and practice of aeroplane design made far greater strides towards becoming an exact science during the four years of War than it had done during the six or seven years preceding it.
