传统的常规飞机都是有尾翼的,包括垂直尾翼和水平尾翼。一般来说只要缺少其一者就称为无尾飞机。而严格地讲,将垂尾和平尾全部去掉的称为无尾飞机,仍保留一部分的称为半无尾(或准无尾)飞机。无尾飞机的主要优点是重量轻、阻力小和隐身性好等。这些优点对战斗机来说都是十分重要的,因此西方国家的不少公司都参与了这一研究项目,目前一个无尾战斗机研究的热潮正在兴起。 Conventional conventional aircraft have a tail, including the vertical tail and horizontal tail. Generally speaking, the lack of one is called a tailless aircraft. Strictly speaking, the tailless tail aircraft, which completely removes the tail and tail, still retains part of the aircraft called semi-tailless (or quasi-tailless) aircraft. The main advantages of a tailless aircraft are light weight, low resistance and good stealth. These advantages are very important for fighter aircraft, so many companies in Western countries are involved in this research project, the current research on a tailless fighter craze is on the rise.
