148 Wilbur Wright has set down the beginnings of the practical experiments made by the two brothers very clearly. 鈥楾he difficulties,鈥?he says, 鈥榳hich obstruct the pathway to success in flying machine construction are of three general classes: (1) Those which relate to the construction of the sustaining wings; (2) those which relate to the generation and application of the power required to drive the machine through the air; (3) those relating to the balancing and steering of the machine after it is actually in flight. Of these difficulties two are already to a certain extent solved. Men already know how to construct wings, or aeroplanes, which, when driven through the air at sufficient speed, will not only sustain the weight of the wings themselves, but also that of the engine and the engineer as well. Men also know how to build engines and screws of sufficient lightness and power to drive these planes at sustaining speed. Inability to balance and steer still confronts students of the flying problem, although nearly ten years have passed (since Lilienthal鈥檚 success). When this one feature has been worked out, the age of flying machines will have arrived, for all other difficulties are of minor importance. Oh, bless you, I'm too old a bird to be caught by any chaff the Ancrams can offer me. Barbara. And I too. Butors de race impertinente, Mrs. Jud. We are delighted to see you. � 色婷亚洲五月,视频黄页,一及e片全过 � Of the Vee type engines shown in Critchley鈥檚 list in 1910, nineteen different sizes were constructed with eight cylinders, and with horse-powers ranging from405 thirty to just over the hundred; the lightest of these weighed 2鈥? lbs. per horse-power鈥攁 considerable advance in design on the average vertical engine, in this respect of weight per horse-power. There were also two sixteen-cylinder engines of Vee design, the larger of which developed 134 horse-power with a weight of only 2 lbs. per brake horse-power. Subsequent developments have indicated that this type, with the further development from it of the double-Vee, or engine with three rows of cylinders, is likely to become the standard design of aero engine where high powers are required. The construction permits of placing every part so that it is easy of access, and the form of the engine implies very little head resistance, while it can be placed on the machine鈥攕upposing that machine to be of the single-engine type鈥攊n such a way that the view of the pilot is very little obstructed while in flight. There was a rather long silence. The big room at the "Blue Bell" was full. It was a room associated in the minds of most of the people present with occasions of festivity or entertainment. The Archery Club balls were held in it. It was used for the exhibitions of any travelling conjurer, lecturer, or musician, whose evil fate brought him to Whitford. Once a strolling company of players had performed there before some fifteen persons and several dozen cane-bottomed chairs. There were the tarnished candelabra stuck in the walls, the little gallery up aloft where the fiddlers sat on ball nights, and the big looking-glass at one end of the room, muffled with yellow muslin, and surmounted by a dusty garland of paper flowers. Now the wintry daylight coming through the uncurtained windows, made all these things look chill, ghastly, and forlorn. People who had thought the "Blue Bell" Assembly Room a cheerful place enough under the bright illumination of wax candles, now shivered, and whispered to each other how dreary it was. Lord Seely was not accustomed to be told that he was under an entire misapprehension on any subject.
