� Certain American radial engines were made previous to 1914, the principal being the Albatross six-cylinder engines of 50 and 100 horse-powers. Of these the smaller size was air-cooled, with cylinders of 4鈥? inches bore and 5 inches stroke, developing the rated power at 1,230 revolutions per minute, with a weight of about 5 lbs. per horse-power. The 100 horse-power size had cylinders of 5鈥? inches bore, developing its rated power at 1,230 revolutions per minute, and weighing only 2鈥?5 lbs. per horse-power. This engine was markedly similar to the six-cylindered Anzani, having all the valves mechanically operated, and with auxiliary exhaust ports at the bottoms of the cylinders, overrun by long pistons. These Albatross engines had their cylinders arranged in two groups of three, with each427 group of three pistons operating on one of two crank pins, each 180 degrees apart. But the careless and the fearful were alike sleeping in their beds now. There was hope that the rain would abate by the morrow; threatenings of a worse kind, from sudden thaws after falls of snow, had often passed off, in the experience of the younger ones; and at the very worst, the banks would be sure to break lower down the river when the tide came in with violence, and so the waters would be carried off, without causing more than temporary inconvenience, and losses that would be felt only by the poorer sort, whom charity would relieve. Cayley did not actually deny the possibility of a man flying by muscular effort, however, but stated that 鈥榯he flight of a strong man by great muscular exertion, though a curious and interesting circumstance, inasmuch as it will probably be the means of ascertaining this power and supplying the basis whereon to improve it, would be of little use.鈥? A new machine, stronger and heavier, was constructed by the brothers, and in the spring of 1904 they began experiments again at Simms Station, eight miles to the east of Dayton, their home town. Press172 representatives were invited for the first trial, and about a dozen came鈥攖he whole gathering did not number more than fifty people. 鈥榃hen preparations had been concluded,鈥?Wilbur Wright wrote of this trial, 鈥榓 wind of only three or four miles an hour was blowing鈥攊nsufficient for starting on so short a track鈥攂ut since many had come a long way to see the machine in action, an attempt was made. To add to the other difficulty, the engine refused to work properly. The machine, after running the length of the track, slid off the end without rising into the air at all. Several of the newspaper men returned next day but were again disappointed. The engine performed badly, and after a glide of only sixty feet the machine again came to the ground. Further trial was postponed till the motor could be put in better running condition. The reporters had now, no doubt, lost confidence in the machine, though their reports, in kindness, concealed it. Later, when they heard that we were making flights of several minutes鈥?duration, knowing that longer flights had been made with airships, and not knowing any essential difference between airships and flying machines, they were but little interested. � 欧美日韩亚洲中文综合视频_鸭子tv_色男人色天堂_美国亚洲成年毛片 Some small mention must be made of seaplane activities, which, round the European coasts involved in the War, never ceased. The submarine campaign found in the spotting seaplane its greatest deterrent, and it is old news now how even the deeply submerged submarines were easily picked out for destruction from a height and the news wirelessed from seaplane to destroyer, while in more than one place the seaplane itself finished the task by bomb dropping. It was a seaplane that gave Admiral Beatty the news that the whole German Fleet was out before the Jutland Battle, news which led to a change of plans that very nearly brought about the destruction of Germany鈥檚 naval power. For the most part, the seaplanes of the War period were heavier than the land machines and, in the opinion of the land pilots, were slow and clumsy things to fly. This was inevitable, for their work demanded more solid building and greater reliability. To put the matter into Hibernian phrase, a forced landing at sea is a much more serious matter than on the ground. Thus255 there was need for greater engine power, bigger wing-spread to support the floats, and fuel tanks of greater capacity. The flying boats of the later War period carried considerable crews, were heavily armed, capable of withstanding very heavy weather, and carried good loads of bombs on long cruises. Their work was not all essentially seaplane work, for the R.N.A.S. was as well known as hated over the German airship sheds in Belgium and along the Flanders coast. As regards other theatres of War, they rendered valuable service from the Dardanelles to the Rufiji River, at this latter place forming a principal factor in the destruction of the cruiser K?nigsberg. Their spotting work at the Dardanelles for the battleships was responsible for direct hits from 15 in. guns on invisible targets at ranges of over 12,000 yards. Seaplane pilots were bombing specialists, including among their targets army headquarters, ammunition dumps, railway stations, submarines and their bases, docks, shipping in German harbours, and the German Fleet at Wilhelmshaven. Dunkirk, a British seaplane base, was a sharp thorn in the German side. And the two women drove together, and sewed together, and talked together; and their talk was chiefly about that exiled victim of unmerited misfortune, Algernon Errington. Rhoda preserved her faith in the Ancram glories. And although she acknowledged to herself that Algernon had treated her badly, he was invested in her mind with some mysterious immunity from the obligations that bind ordinary mortals. � Barbara.
