By 1913, eight different sizes of the Gnome engine were being constructed, ranging from 45 to 180 brake horse-power; four of these were single-crank engines, one having nine and the other three having seven cylinders. The remaining four were constructed with two cranks; three of them had fourteen cylinders apiece, ranged in groups of seven, acting on the cranks, and the one other had eighteen cylinders ranged in two433 groups of nine, acting on its two cranks. Cylinders of the two-crank engines are so arranged (in the fourteen-cylinder type) that fourteen equal angular impulses occur during each cycle; these engines are supported on bearings on both sides of the engine, the air-screw being placed outside the front support. In the eighteen-cylinder model the impulses occur at each 40 degrees of angular rotation of the cylinders, securing an extremely even rotation of the air-screw. Yes; it is now half-past eight. I have an appointment. At least鈥擨 shall be back in an hour, I have no doubt. V THE HORIZONTALLY-OPPOSED ENGINE When Lydia was gone, Algernon lit a cigar and drew up his chair to the fireside, where he sat silent, staring at his elegantly-slippered feet on the fender. Castalia rose, fidgeted about the room, walked to the door, stopped, turned back, and, standing directly opposite to Algernon, said querulously, "Do you mean to remain here?" And who the devil is Mr. Gladwish? The light weight of the Wright brothers鈥?engine did not necessitate a high number of revolutions per minute to get the requisite power; the speed was only 1,300 revolutions per minute, which, with a piston stroke of 3.94 inches, was quite moderate. Four cylinders were used, the cylinder diameter being 4.42 inches; the engine was of the vertical type, arranged to drive two propellers at a rate of about 350 revolutions per minute, gearing being accomplished by means of chain drive from crank-shaft end to propeller spindle. 欧美成 人 在线播放|在线综合 亚洲 欧美 See it for myself?
