萊特兄弟
Key words: inventor
The Wright Brothers
Aviation pioneers, inventors. Wilbur was born near Millville, Indiana, and Orville was born in Dayton, Ohio. The sons of a minister of the United Brethren Church, the Wright brothers showed mechanical genius from boyhood, although neither graduated from high school.
In 1892 they opened a bicycle sales and repair shop in Dayton and soon were making and selling their own bicycles. Reading about experiments with gliders spurred their interest in flight, and they built their first glider in 1899, a biplane kite with wings that could be twisted mechanically.
The brothers made their first trip to Kitty Hawk, North Carolina in 1900 to conduct glider experiments on the sand hills there.
Back in Dayton they built the first wind tunnel and prepared their own tables of lift-pressures for various wing surfaces and wind speeds. They also built a powerful four-cylinder engine and an efficient propeller, and in September 1903 they returned to Kitty Hawk. Bad weather delayed the testing of this aircraft until December 17, 1903, when Orville piloted it on a flight of 12 seconds and 120 feet; Wilbur flew later in the day, staying aloft for 59 seconds to cover 852 feet.
The brothers built two sturdier, more reliable planes over the next two years and in 1906 received a U.S. patent for a powered aircraft. Initially they sold their plane to the British and French governments, but in 1908 the U.S. War Department contracted for a Wright flying machine for the army. In 1909 they formed the American Wright Company and proceeded to manufacture their improved planes and to train pilots.
Wilbur, a bachelor as was his brother, died of typhoid in May 1912. In 1915, Orville - who had continued to test fly all his planes - retired from the aircraft manufacturing business to pursue his own research interests. During World I he accepted a commission as a major to serve as a consultant to the army air service and he served for many years on the National Advisory Committee for Aeronautics.
萊特兄弟是美國飛機發明家,航空先驅者。1903 年成功地進行了第一架可操縱的動力飛機的持續飛行,1905 年制造和飛行了第一架實用的飛機。
1867 年4 月16 日,維爾伯賴特出生于印第安納米爾維爾。1871 年8 月19 日,奧維爾賴特出生于美國俄亥俄代頓。主教之子。早年主要靠自學設計和制造印刷機械和自行車。維爾伯產生動力飛行的想法是受O.利林塔爾的影響。通過觀察鷹在空中保持平衡的情況,1899年維爾伯認識到飛機要能飛行,必須能繞3 個軸轉動即能向兩側傾斜,能升降,能向左右轉彎。1899 年萊特兄弟制造第一架雙翼機時安裝了機械扭曲機翼,即在一側機翼升力增加的同時,另一側機翼升力減小,由此操縱飛機壓坡度轉彎或由滾轉改為平飛。他們的功績除了完成有動力的飛機飛行外,繞3 個軸操縱飛機是他們對空氣動力學和飛行方面的主要貢獻。
為了實現動力飛行,他們決定先掌握滑翔飛行技術。1900 年 1902 年制造3 架雙翼滑翔機并作了飛行。最后一架滑翔機有升降舵、方向舵和扭曲機翼。他們制造滑翔機時進行了大量理論工作和實驗工作,包括風洞試驗。他們還設計和制造了實現動力飛行所必需的螺旋槳和輕型發動機。
1903 年人類歷史上第一架有動力裝置的飛機飛行家1 號制造成功,12 月17 日凌晨該機從平地起飛。第一次飛行12 秒,最后一次59 秒,飛行距離260 米。1904 年飛行家2 號飛行成功。
1905 年制造的飛行家3 號是世界上第一架實用的飛機,能轉彎、傾斜、做圓圈飛行和8 字飛行,續航時間超過半小時。1905 年10 月16 日至1908 年5 月6 日,因財政拮據,萊特兄弟未進行過一次飛行。1908 年維爾伯在法國作飛行表演,5 個月內飛行100 多次,總飛行時間超過25 小時,其中約60 次帶乘客飛行,有7 次飛行時間超過1 小時,最后一次飛行時間達2 小時 20 分。
與此同時奧維爾也在美國作轟動一時的表演飛行,并為美國陸軍制造了世界上第一架軍用飛機。1909 年之前,世界航空可說在萊特兄弟統治之下,他們同時在歐洲和美國制造飛機。
以上就是關于萊特兄弟的SAT寫作素材的全部內容,包括了英文和中文兩個版本,非常實用。大家在備考相關的SAT寫作話題的時候,可以根據自己的實際情況,選擇這個素材進行適當的組合和描述。
