關(guān)于飛碟設(shè)計與生產(chǎn)人類也并非不能實現(xiàn),據(jù)傳早在二戰(zhàn)期間納粹德國已經(jīng)設(shè)計并制作試飛這種飛行器。 當(dāng)然但這也只是傳言,并沒有被證實。 1940年末,納粹德國成立了一個名為“爆破手研究室-13”的秘密機構(gòu),其任務(wù)是專門研究、制造秘密飛行器。該秘密機構(gòu)收羅了第三帝國最杰出、最優(yōu)秀的專家、工程師和試飛員等頂尖人才,在德國軍方協(xié)助下,終于制造出了一種最先進的碟形飛行器——“別隆采圓盤”。 飛碟與飛機相比其主要優(yōu)勢有四: 1,采用圓盤式結(jié)構(gòu),各方向中心軸對稱受力均勻,可實現(xiàn)任意方向轉(zhuǎn)彎; 2,采用垂直起降方式,可任意對稱分布發(fā)動機,可空懸停; 3,可安裝多個發(fā)動機和多方向安裝發(fā)動機,動力大; 4,側(cè)面投影面積小,側(cè)面雷達反射面積基本可以做到無反射狀態(tài),非常適合空戰(zhàn)。 另外由于飛碟特殊的外形,還可以做為太空飛行器。 不明飛行物(Unknown Flying Object) We all know that we live in a complex world .Although the technics of the human beings are developing all the time , we still got so many unsolved problems. Among 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 UFO is just a bird , a plane , a balloon or even a plastic bag . Until now ,we haven't found any clues on real extraterrestrial civilization or supernatural phenomenon .But we are 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!
