世界上第一架全金属飞机——F13旅客机是由德国飞机设计师胡果?容克斯设计研制的,他开启了飞机的全金属时代。在20世纪20年代以前,飞机采用木质结构是主流。1903年,莱特兄弟研制的世界第一架飞机就是木质的,其机体包括骨架、支柱和翼肋用云杉木制成,螺旋桨则用胡桃木制造,机翼蒙皮使用亚麻布,只有少数承力件用金属杆。木质飞机质量轻,加工简易,成本低廉。早期的飞机发动机功率小、飞行速度低,因而机翼翼面承受的载荷也小,
The world’s first all-metal aircraft - F13 passenger aircraft by the German aircraft designer Hugo? Junkers design and development, he opened the plane’s all-metal era. Before the 1920s, the use of wooden structures for the aircraft was the mainstream. In 1903, the world’s first aircraft developed by the Wright brothers was woody. Its body consisted of skeletons, pillars and ribs made of spruce wood, propellers made of walnut, wing skins made of linen, and only a few bearings Power with metal rod. Wood aircraft light weight, simple processing, low cost. Early aircraft engine power, flying speed is low, so wing wing surface to bear the load is small,
