鸟的尾翼是用来控制平衡的,没有它,鸟就不能在空中自由自在地飞翔。飞机的发明受鸟的启示,因此,飞机也和鸟一样有翅膀和尾翼。和鸟类不同的是,发明飞机的人是高级动物,能通过学习不断进步。随着高新技术越来越多地运用于航空领域,未来飞机的发展将摆脱尾翼的束缚,使其技术性能获得长足的进步。 无尾战机与传统战机相比.有众多好处。首先是将明显减少战斗机的重量。一般说来,因为尾部离飞机重心最远,所以尾部重量减少一公斤对飞机的影响相当于机体其他部位重量减少两公斤,而尾部重量一般要占到全机最大起飞重量的6％～7％。此外,
The tail of a bird is used to control the balance. Without it, the bird can not fly freely in the air. The invention of the airplane is inspired by the birds, so the airplane has wings and empennage just like a bird. Unlike birds, people who invent aircraft are advanced animals and can learn to make progress. With the increasing use of high-tech in the aviation field, the future development of the aircraft will get rid of the shackles of the tail and make great progress in its technical performance. Compared to the traditional fighter, the tailless fighter has many advantages. The first is to significantly reduce the weight of the fighter. In general, because the tail is farthest away from the center of gravity of the aircraft, reducing the weight of a tail by one kilogram will reduce the weight of other parts of the body by two kilograms, while the tail weight generally accounts for 6% -7% of the maximum takeoff weight of the aircraft. . In addition,
