She made no further remark, and Jack who had counted on creating more of an effect than this, felt a little aggrieved. You never could get any change out of this girl, he reflected. But just let her wait! She was due to be surprised for once in her young life! I wish she was at the bottom of the Thames! Although French and German experiment in connection with the production of an airship which should be suitable for military purposes proceeded side by side, it is necessary to outline the development in the two countries separately, owing to the differing character of the work carried out. So far as France is concerned, experiment began with the Lebaudy brothers, originally sugar refiners, who turned their energies to airship construction in 1899. Three years of work went to the production of their first vessel, which was launched in 1902, having been constructed by them together with a balloon manufacturer named Surcouf and an engineer, Julliot. The Lebaudy airships were what is known as semi-rigids, having a spar which ran practically the full length of the gas bag to which it was attached in such a way as to distribute the load evenly. The car was suspended from the spar, at the rear end of which both horizontal and vertical rudders were fixed, whilst stabilising fins were provided at the stern of the gas envelope itself. The first of the Lebaudy vessels was named the 鈥楯aune鈥? its length was 183 feet and its maximum diameter 30 feet, while the cubic capacity was 80,000 feet. The power unit was a 40 horse-power Daimler motor, driving two propellers and giving a maximum speed of 26 miles per hour.349 This vessel made 29 trips, the last of which took place in November, 1902, when the airship was wrecked through collision with a tree. He concerns himself also with the most difficult problem that confronts the flying man of to-day, namely, landing effectively, and his remarks on this subject would be instructive even to an air pilot of these days: 鈥楴ow the ways and means by which the speed is slackened at the end of a flight are these. The bird spreads its wings and tail so that their concave surfaces are perpendicular to the direction of motion; in this way, the spreading feathers, like a ship鈥檚 sail, strike against the still air, check the speed, and so that most of the impetus may be stopped, the wings are flapped quickly and strongly forward, inducing a contrary motion, so that the bird absolutely or very nearly stops.鈥? 色久久综合-天天干-久久婷婷五月综合色啪-色姑娘综合站 No, he wouldn't. Uncle Val would never enjoy what vexed me. My lady might; nasty, disagreeable old thing! She answered so faintly that he had to strain his ear to hear her, and her colourless lips trembled as the lips tremble of a person trying to keep back tears. But her eyes were quite dry. It was evident, however, that there could only be so many triangles a week鈥攁nd besides, "the eternal triangle" was in itself condemned by its mere ancient origin. What next? I guessed right鈥攂olshevism, of course.
