plane是谁发明的
plane是谁发明的 关于飞碟设计与生产人类也并非不能实现，据传早在二战期间纳粹德国已经设计并制作试飞这种飞行器。 当然但这也只是传言，并没有被证实。 1940年末，纳粹德国成立了一个强功名为“爆破手研究室－13”的秘密机构，其任务是专门研究、制造秘密飞行器。该秘密机构收罗了第三帝国最杰出、最优秀的专家、工程师和试飞员等顶尖人才，在德国军方协助下，终于制造出了一种最先进的碟形飞行器——“别隆采圆盘”。 飞碟与飞机相比其主要优势有四： 1，采用圆盘式结构，各方向中心轴对称受力均匀，可实现任意方向转弯； 2，采用垂直起降方式，可任意对称分布发动机，可空悬停； 3，可安装多个发动机和多方向安装发动机，动力大； 4，侧面投影面积小，侧面雷达反射面积基本可以做到无反射状态，非常适合空战。 另外由于飞碟特殊的外形，还可以做为太空来自飞行器。 不明飞行物(Unknown Flying Object) We all know that we live in a complex world .Although the technics of the h机呀感哪玉积指uman bein树花国字诗复曾究侵的gs are developing all the time , we still got so many unsolved problems. Among 案无粒远all of this puzzles , UFO is one of the most noticable things. Now as everybody knows ,UFO is what we call Unknown Flying Object for short.For a period of time ,once we mentioned UFO , we always communicate it with high-tech ,extra-terrestrials ,outter space culture and many other exciting things . There are a lot of witnesses around the world ,affirming that they chanced to have seen some strange things in the sky . However , most of them cannot hand in the credible evidence .That's a pity. With the long-term efforts of the ufologists , most of the incidents are finally considered as natural phenomenons or human conducts . Some so-called U或易更推降局固FO is just a bird , a plane , a balloon or even a plas巴tic bag . Until no孩江w ,we haven't found any clues on real extraterrestrial civilization or supernatural phenomenon .But we are 油山问信燃载入依willing to see , with the constant exertion of humanity,we will get more profound knowledge , we will get to realize the essence of the world.We have the faith! 是老外发明的……… 反正不是我们发明的哈哈~！！！！！！！！！:)
