VII ENGINES OF THE WAR PERIOD And suddenly, emerging from the ruins, we came on a Moslem street with high walls, windowless, and waving plumes of banyan and palm trees rising above the houses. The principal engines of British, French, and American design used in the war period and since are briefly described under the four distinct types of aero engine; such notable examples as the Rolls-Royce, Sunbeam, and Napier engines have been given special mention, as they embodied鈥攁nd still embody鈥攁ll that is best in aero engine practice. So far, however, little has been said about the development of German aero engine design, apart from the early Daimler and other pioneer makes. 彩票中奖领奖多久过期 And suddenly, emerging from the ruins, we came on a Moslem street with high walls, windowless, and waving plumes of banyan and palm trees rising above the houses. Horatia. One would suppose them sometimes prophetical of future events. Who can deny that Hanover.... The handle clicked, the door was opened and sharply shut again, and the Whitford postmaster disappeared into his private room. � CHAPTER XVII. A cruelty consecrated among most nations by custom is the torture of the accused during his trial, on the pretext of compelling him to confess his crime, of clearing up contradictions in his statements, of discovering his accomplices, of purging him in some metaphysical and incomprehensible way from infamy, or finally of finding out other crimes of which he may possibly be guilty, but of which he is not accused. � The 1905 machine was, like its predecessors, a biplane with a biplane elevator in front and a double vertical rudder in rear. The span was 40 feet, the chord of the wings being 6 feet and the gap between them about the same. The total area was about 600 square feet which supported a total weight of 925 lbs.; while the motor was 12 to 15 horse-power driving two284 propellers on each side behind the main planes through chains and giving the machine a speed of about 30 m.p.h. One of these chains was crossed so that the propellers revolved in opposite directions to avoid the torque which it was feared would be set up if they both revolved the same way. The machine was not fitted with a wheeled undercarriage but was carried on two skids, which also acted as outriggers to carry the elevator. Consequently, a mechanical method of launching had to be evolved and the machine received initial velocity from a rail, along which it was drawn by the impetus provided by the falling of a weight from a wooden tower or 鈥榩ylon.鈥?As a result of this the Wright aeroplane in its original form had to be taken back to its starting rail after each flight, and could not restart from the point of alighting. Perhaps, in comparison with French machines of more or less contemporary date (evolved on independent lines in ignorance of the Americans鈥?work), the chief feature of the Wright biplane of 1905 was that it relied entirely upon the skill of the operator for its stability; whereas in France some attempt was being made, although perhaps not very successfully, to make the machine automatically stable laterally. The performance of the Wrights in carrying a loading of some 60 lbs. per horse-power is one which should not be overlooked. The wing loading was about 1? lbs. per square foot. Lock Willow? Wrong. The Adirondacks with Sallie? Wrong. In England, the first vertical aero engine of note was that designed by Green, the cylinder dimensions being 4.15 inch diameter by 4.75 stroke鈥攁 fairly complete idea of this engine can be obtained from the accompanying diagrams. At a speed of 1,160 revolutions per minute it developed 35 brake horse-power, and by accelerating up to 1,220 revolutions per minute a maximum of 40 brake horse-power could be obtained鈥攖he first-mentioned was the rated working speed of the engine for continuous runs. A flywheel, weighing 23.5 lbs., was fitted to the engine, and this, together with the ignition system, brought the weight up to 188 lbs., giving 5.4 lbs. per horse-power. In comparison with the engine fitted to the Wrights鈥?aeroplane a greater power was obtained from approximately the same cylinder volume, and an appreciable saving in weight had also been effected. The illustration shows the arrangement of the vertical valves at the top of the cylinder and the overhead cam shaft, while the position of the carburettor and inlet pipes can be also seen. The water jackets were formed by thin copper casings, each cylinder being separate and having its independent jacket rigidly fastened to the cylinder at the top only, thus allowing for free expansion of the casing; the joint at the bottom end was formed by sliding the jacket over a rubber ring. Each cylinder was bolted to the crank-case and set out of line with the crankshaft, so that the crank has passed over the upper dead centre by the time that the piston is at the top of its stroke when receiving the full force of fuel explosion. The advantage of this desaxe setting is that the pressure in398 the cylinder acts on the crank-pin with a more effective leverage during that part of the stroke when that pressure is highest, and in addition the side pressure of the piston on the cylinder wall, due to the thrust of the connecting rod, is reduced. Possibly the charging of the cylinder is also more complete by this arrangement, owing to the slower movement of the piston at the bottom of its stroke allowing time for an increased charge of mixture to enter the cylinder. And suddenly, emerging from the ruins, we came on a Moslem street with high walls, windowless, and waving plumes of banyan and palm trees rising above the houses. Sophia. Down, Adonis, down! your dirty little paws....
