2025未来概念飞行器编辑本段回目录
迄今为止，NASA已公布三种未来飞行器概念图，安静，节能，有望在2025年飞向蓝天。
下面这组震撼人心的图片并非来自科幻影片，而是美国国家航空航天局（NASA）推出的未来航空器的最新式样，其中包括即将面世的新一代空中客车。迄今为止，NASA已公布三种未来飞行器概念图，安静，节能，有望在2025年飞向蓝天。
据《每日邮报》1月17日报道，截止去年年底，世界三大航空航天公司洛克希德--马丁、诺斯罗普•格罗曼和波音公司各自推出未来飞机设计方案，均获得NASA 2011年研制开发合同。这三种未来主义设计风格的“超级飞行器”都有机会成为现实。它们有着共同设计理念：更快，更大，更安静，燃料更环保。
NASA为飞机的时速、航程和有效载荷量设置了最低参数。2011年是三家公司紧张研发的一年，要对各自设计的概念飞机进行模拟测试，谁能被NASA选中很难预料。不过有人对这项工程提出质疑，认为一架大型的航空器从设计草图到正式投产需反复检测，多方改进，就连梦幻波音787也不例外。

未来飞行器概览 
NASA太阳能扑翼飞行器（Solar Flapper）突破传统设计理念，以太阳能为动力，可以拍动翅膀，驱动机身向上向前飞行。
工业设计师Luigi Colani为日本航空公司设计的概念飞机。
飞向无限!(语出玩具总动员)：“海雀”式小型私人飞机的设计理念完全来自影片《玩具总动员》中的巴斯光年（Buzz Lightyear）。目标时速150mph航程50英里（约80公里）。
未来世界“绿色飞碟”，不但充满太空时代的幻想，而且加入了生态环保元素。
空中游艇：ML886超级豪华飞艇
ICON A5轻型飞机，水面陆地均能起降，享受极限驾驶快乐。水面降落时收起32英尺长的机翼，变身水上游艇。可轻松置身于大型车库中。
Criteria set by Nasa meant that each design had to fly up to 85 per cent of the speed of sound, cover a range of about 7,000 miles and carry between 50,000lbs and 100,000lbs of payload; either cargo or passengers.
Now, each of the three companies will spend the rest of this year exploring, testing and simulating their designs in the hope that Nasa will choose it for development.
Cleaner: All three designs - including this one from Lockheed Martin - were required to have green credentials
How likely it is for these designs to get off the ground is under debate. A spokesman from technology and innovation website Fast Company told the Huffington Post: 'Given how long it usually takes to craft an aircraft from scratch, and bearing in mind how many technical hitches the revolutionary Boeing 787 Dreamliner has suffered, these are the sorts of aircraft that these three firms are probably beginning to design for real right about now.'
Scroll down for other weird and wonderful designs of aircraft for the future...
Nasa's Solar Flapper is an unconventional concept for a plane that would use solar power and flapping of the aircraft's 'wings' to propel itself up and forward
Industrial designer Luigi Colani came up with this concept for Japan Airlines
To infinity and beyond: The 'Puffin' Personal Aircraft concept by Nasa bears more than a passing resemblance to Toy Story's Buzz Lightyear. It is targeted to reach speeds of more than 150mph with a range of about 50 miles
This futuristic 'flying saucer' design is not only space-age but eco-friendly too, designed by the CleanEra project, led by Etnel Straatsma of Delft University of Technology in The Netherlands
The Flying Yacht: The Aeroscraft ML866 offers the ultimate luxury experience
The Icon A5 is known as the 'ultimate joyride' and can take off and land on water or dry land and, when its 32-foot wings are folded, it can fit comfortably into a large garage
