But what can I say? she asked. "What excuse can I make? I hate to worry Uncle Val. It isn't as if he had more money than he knew what to do with. And if Lady Seely knew about his helping us, she would lead him such a life!" Charles. Where on earth are you taking me? "Mike brought it from the farm," she said. 鈥淵ou are very gracious, Mademoiselle Corinne. But why take it from me as soon as it is given?鈥? For one day more must sicken in suspense.鈥? The question of reducing the resistance by adopting 鈥榮tream-line鈥?forms, along which the air could flow uninterruptedly without the formation of eddies, was not at first properly realised, though credit should be given to Edouard Nieuport, who in 1909 produced a monoplane with a very large body which almost completely enclosed the pilot and made the machine very294 fast, for those days, with low horse-power. On one of these machines C. T. Weymann won the Gordon-Bennett Cup for America in 1911, and another put up a fine performance in the same race with only a 30 horse-power engine. The subject, was however, early taken up by the British Advisory Committee for Aeronautics, which was established by the Government in 1909, and designers began to realise the importance of streamline struts and fuselages towards the end of this transition period. These efforts were at first not always successful and showed at times a lack of understanding of the problems involved, but there was a very marked improvement during the year 1912. At the Paris Aero Salon held early in that year there was a notable variety of ideas on the subject; whereas by the time of the one held in October designs had considerably settled down, more than one exhibitor showing what were called 鈥榤onocoque鈥?fuselages completely circular in shape and having very low resistance, while the same show saw the introduction of rotating cowls over the propeller bosses, or 鈥榮pinners,鈥?as they came to be called during the War. A particularly fine example of stream-lining was to be found in the Deperdussin monoplane on which V茅drines won back the Gordon-Bennett Aviation Cup from America at a speed of 105鈥? m.p.h.鈥攁 considerable improvement on the 78 m.p.h. of the preceding year, which was by no means accounted for by the mere increase in engine power from 100 horse-power to 140 horse-power. This machine was the first in which the refinement of 鈥榮tream-lining鈥?the pilot鈥檚 head, which became a feature of subsequent racing machines, was introduced. This consisted of a circular padded295 excresence above the cockpit immediately behind the pilot鈥檚 head, which gradually tapered off into the top surface of the fuselage. The object was to give the air an uninterrupted flow instead of allowing it to be broken up into eddies behind the head of the pilot, and it also provided a support against the enormous wind-pressure encountered. This true stream-line form of fuselage owed its introduction to the Paulhan-Tatin 鈥楾orpille鈥?monoplane of the Paris Salon of early 1912. Altogether the end of the year 1912 began to see the disappearance of 鈥榝reak鈥?machines with all sorts of original ideas for the increase of stability and performance. Designs had by then gradually become to a considerable extent standardised, and it had become unusual to find a machine built which would fail to fly. The Gnome engine held the field owing to its advantages, as the first of the rotary type, in lightness and ease of fitting into the nose of a fuselage. The majority of machines were tractors (propeller in front) although a preference, which died down subsequently, was still shown for the monoplane over the biplane. This year also saw a great increase in the number of seaplanes, although the 鈥榝lying boat鈥?type had only appeared at intervals and the vast majority were of the ordinary aeroplane type fitted with floats in place of the land undercarriage; which type was at that time commonly called 鈥榟ydro-aeroplane.鈥?The usual horse-power was 50鈥攖hat of the smallest Gnome engine鈥攁lthough engines of 100 to 140 horse-power were also fitted occasionally. The average weight per horse-power varied from 18 to 25 lbs., while the wing-loading was usually in the neighbourhood of 5 to 6 lbs. per square foot. The average speed ranged from 65-75 miles per hour. 久久机热视频/这里只有精品/99热视频只有精品国产 鈥淟ook here, master, I can guess what all this is about 鈥?now before I goes I want to have a word with you.鈥? 鈥淲e were just beginning an interesting little talk when you were called off,鈥?she remarked. "Having secured the rope at both ends, the workmen were enabled to haul over larger ones. A trestle ten feet high was then erected on each side of the channel, and two ropes stretched across the tops of the trestles and fastened at each end to the rocks. These were allowed to be slack, in order to give greater strength. The next step was to have a foot passage to allow workmen to communicate with each other, and with this object the ropes were placed four feet apart and planked over, and a rope hand-rail made on each side. Chains were then placed across over trestles in a similar manner, and planked on top, until the planking from each shore reached within ten feet of joining in the middle, when the chain broke and precipitated the workmen and their tools into the channel. Three of our best men were drowned. The others swam ashore. It was only right, however, that Ernest should pay half the cost of the watch; this should be made easy for him, for it should be deducted from his pocket-money in half-yearly installments extending over two, or even it might be three years. In Ernest鈥檚 own interests, then, as well as those of as well as those of his father and mother, it would be well that the watch should cost as little as possible, so it was resolved to buy a second-hand one. Nothing was to be said to Ernest, but it was to be bought, and laid upon his plate as a surprise just before the holidays were over. Theobald would have to go to the county town in a few days, and could then find some second-hand watch which would answer sufficiently well. In the course of time, therefore, Theobald went, furnished with a long list of household commissions, among which was the purchase of a watch for Ernest.
