面对未来民用客机在节油、减排和降噪等环保性能的越来越苛刻的要求,采用传统常规气动布局的客机已无更多潜力可挖,美国NASA认为,机翼/机身融合体飞翼布局设计,是唯一能满足2020年运载能力、使用效率,特别是激进的环保指标要求的解决途径。波音公司的鬼怪工程队正在领导着X-48B翼身融合体无人驾驶技术验证机的试飞和研究工作,它还和NASA以及美国多所大学合作对800座级和450座级的翼身融合体布局客机设计方案进行了深入和详细的论证和研究工作,获得了许多有益的结论和经验。半个世纪以来,虽然大型民用客机在气动设计、材料结构、制造工艺、航电设备和发动机等关键技术领域都取得了飞跃式的技术进步,但是大型民用客机的气动布局形式却一直没有取得重大的突破,气动效率基本没有大的提升,几十年
Faced with the increasingly demanding requirements of civil aircraft on environmental performance such as fuel economy, emission reduction and noise reduction in the future, passenger aircraft adopting the conventional conventional aerodynamic layout have no more potential to be tapped. According to the NASA, the wing / fuselage integration Body flying wing layout design, is the only way to meet the 2020 carrying capacity, efficiency, especially the radical requirements of environmental protection solutions. Boeing's ghost engineering team is leading the flight and research efforts of the X-48B wing-fuselage driverless technology demonstrator. It is also partnered with NASA and several U.S. universities to fuse the 800-seater and 450-seater wing Body layout of passenger aircraft design program conducted in-depth and detailed demonstration and research work, and obtained many useful conclusions and experiences. For half a century, despite the rapid technological progress made in the area of aerodynamic design, material structure, manufacturing process, avionics equipment and engines, the aerodynamic layout of large commercial passenger aircraft has not been materialized The breakthrough, the basic aerodynamic efficiency is not greatly improved, for decades
