The propeller was the only part of their airship they had not studied when they began to build. 鲁伯特·萨金特·荷兰.历史性发明.
Their airship flew well in a straight course, but there was difficulty in turning corners. 鲁伯特·萨金特·荷兰.历史性发明.
Their work is in the shops, devising improvements that will make the airship safer and better fitted for commercial uses. 鲁伯特·萨金特·荷兰.历史性发明.
After many experiments they succeeded, and on December 17, 1903, the first airship made four flights at Kitty Hawk. 鲁伯特·萨金特·荷兰.历史性发明.

The great audience, watches in hand, kept their eyes on the airship. 鲁伯特·萨金特·荷兰.历史性发明.
On the return the airship met with strong downward currents of air that bore it groundward until it was hidden by the tops of trees. 鲁伯特·萨金特·荷兰.历史性发明.
On May 10, 1908, ten ascensions in the government airship were made, the longest being over a mile and a half. 鲁伯特·萨金特·荷兰.历史性发明.
The elapsed time of the flight was fourteen minutes and forty-two seconds, which meant that the airship had attained a speed of a little more than forty-two miles an hour. 鲁伯特·萨金特·荷兰.历史性发明.
Speed was a very important factor in the government’s specifications for a successful airship, and the price to be paid depended on this, which had been calculated to be forty miles an hour. 鲁伯特·萨金特·荷兰.历史性发明.
In the distance we saw the bright-white light of an approaching airship, but we attached no special significance to so common a sight. 埃德加·赖斯·巴勒斯.火星公主.
They had been in no hurry, and when they built their first real airship they made use of all the principles of aerodynamics that they had discovered. 鲁伯特·萨金特·荷兰.历史性发明.
Then the airship began to descend, taking the circles easily, and finally skimming down to the ground. 鲁伯特·萨金特·荷兰.历史性发明.
The Wrights realized that a more automatic method of meeting these changes must be found, and they worked it out by shifting the rudder and the surfaces of the airship as it met the air-currents. 鲁伯特·萨金特·荷兰.历史性发明.
The aviation week at Rheims was followed by other great airship meets in other countries. 鲁伯特·萨金特·荷兰.历史性发明.
The man?uvre showed how easily the airships were controlled. 鲁伯特·萨金特·荷兰.历史性发明.
The public could not understand how these two men, bicycle-makers of Dayton, had learned so much about airships. 鲁伯特·萨金特·荷兰.历史性发明.
Control of the airships was shown to a remarkable degree. 鲁伯特·萨金特·荷兰.历史性发明.
