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.
莱特兄弟是美国飞机发明家,航空先驱者。1903 年成功地进行了第一架可操纵的动力飞机的持续飞行,1905 年制造和飞行了第一架实用的飞机。
1867 年4 月16 日,维尔伯赖特出生于印第安纳米尔维尔。1871 年8 月19 日,奥维尔赖特出生于美国俄亥俄代顿。主教之子。早年主要靠自学设计和制造印刷机械和自行车。维尔伯产生动力飞行的想法是受O.利林塔尔的影响。通过观察鹰在空中保持平衡的情况,1899年维尔伯认识到飞机要能飞行,必须能绕3 个轴转动即能向两侧倾斜,能升降,能向左右转弯。1899 年莱特兄弟制造第一架双翼机时安装了机械扭曲机翼,即在一侧机翼升力增加的同时,另一侧机翼升力减小,由此操纵飞机压坡度转弯或由滚转改为平飞。他们的功绩除了完成有动力的飞机飞行外,绕3 个轴操纵飞机是他们对空气动力学和飞行方面的主要贡献。
