During one of his vision-seeking runs through the rain forest, the newly reborn Micah True met abeautiful young woman from Seattle who was visiting on vacation. They couldn鈥檛 have been moredifferent鈥擬elinda was a psychology grad student and the daughter of a wealthy investmentbanker, while Micah was, quite literally, a caveman鈥攂ut they fell in love. After a year in thewilderness, Micah decided it was time to return to the world. 鈥淚 think he also goes by Micah True,鈥?I said. 鈥淏ut I鈥檓 not sure if that鈥檚 really his name or hisdog鈥檚.鈥? 鈥淲hy?鈥? A careful consideration of the salient features leading to maximum efficiency in aeroplanes鈥攑articularly in regard to speed and climb, which were the two most important military requirements鈥攕howed that a vital feature was the reduction in the amount of weight lifted per horse-power employed; which in 1914 averaged from 20 to 25 lbs. This was effected both by gradual increase in the power and size of the engines used and by great improvement in their detailed design (by increasing compression ratio and saving weight whenever possible); with the result that the motive power of single-seater aeroplanes rose from 80 and 100 horse-power in 1914 to an average of 200 to 300 horse-power, while the actual weight of the engine fell from 3?-4 lbs. per horse-power to an average of 2? lbs. per horse-power. This meant that while a pre-war309 engine of 100 horse-power would weigh some 400 lbs., the 1918 engine developing three times the power would have less than double the weight. The result of this improvement was that a scout aeroplane at the time of the Armistice would have 1 horse-power for every 8 lbs. of weight lifted, compared with the 20 or 25 lbs. of its 1914 predecessors. This produced a considerable increase in the rate of climb, a good postwar machine being able to reach 10,000 feet in about 5 minutes and 20,000 feet in under half an hour. The loading per square foot was also considerably increased; this being rendered possible both by improvement in the design of wing sections and by more scientific construction giving increased strength. It will be remembered that in the machine of the very early period each square foot of surface had only to lift a weight of some 1? to 2 lbs., which by 1914 had been increased to about 4 lbs. By 1918 aeroplanes habitually had a loading of 8 lbs. or more per square foot of area; which resulted in great increase in speed. Although a speed of 126 miles per hour had been attained by a specially designed racing machine over a short distance in 1914, the average at that period little exceeded, if at all, 100 miles per hour; whereas in 1918 speeds of 130 miles per hour had become a commonplace, and shortly afterwards a speed of over 166 miles an hour was achieved. She did not seem to him to be actually crying, but the ritual of crying was there, and had to be respected. 亚洲人成视频在线播放免费人成视频_欧美成人网站 免费观看 Ha! And you also opened my desk at the office, and took out letters and papers! Do you know what people are called who do such things? said Algernon, now in a white heat of anger. After the adjustments for actual flight had been made in the Curtiss factory, according to the minute descriptions contained in the Langley Memoir on Mechanical Flight, the aeroplane was taken to the shore of Lake Keuka, beside the Curtiss hangars, and assembled for launching. On a clear morning (May 28th) and in a mild breeze, the craft was lifted on to the water by a dozen men and set going, with Mr Curtiss at the steering wheel, esconced in the little boat-shaped car under the forward part of the frame. The four-winged craft, pointed somewhat across the wind, went skimming over the wavelets, then automatically headed into the wind, rose in level poise, soared gracefully for 150 feet, and landed softly on the water near the shore. Mr Curtiss asserted that he could have flown farther, but, being unused to the machine, imagined that the left wings had more resistance than the right. The truth is that the aeroplane was perfectly balanced in wing resistance, but turned on the water245 like a weather vane, owing to the lateral pressure on its big rear rudder. Hence in future experiments this rudder was made turnable about a vertical axis, as well as about the horizontal axis used by Langley. Henceforth the little vertical rudder under the frame was kept fixed and inactive.7 The discovery of Minnie Bodkin's note in Algernon's secretaire at the office had incited Castalia to make some other attempts to pry into that depository of her husband's papers. She made excuses to step into the post-office whenever she had any reason for thinking Algernon was absent. Sometimes it was with the pretence of wishing to see him, sometimes on the plea of wanting to rest. She had learned that her husband frequently went into the "Blue Bell," to have luncheon, in the middle of the day; and that, from one cause or another, the Whitford Post-office was not really honoured with so much of his personal superintendence as she had been led to suppose. And this again was a fertile source of self-tormenting. Where was he, when he was not at the office? No one loves me, returned Castalia, with white rigid lips. Then she got up from the bench, and went back into her own garden and into the house, with the air of a person walking in sleep.
