发明飞机的灵感源于人们对鸟儿飞行的认识,然而飞机的机翼却无法像鸟的翅膀那样自由地伸展和舞动,所以也就不能像鸟一样适应各种飞行状态。不过,随着技术的发展,像鸟翅膀一样的变形机翼将很快面世。美国防部预先研究计划局于两年前启动的“变形飞机结 The invention of the airplane was inspired by one’s knowledge of the flight of a bird, yet its wings did not stretch and dance freely like the wings of a bird, so they did not adapt to the various states of flight as birds did. However, as the technology evolves, wings like the deformation of the wings will soon be available.
