翼身融合(Blended Wing Body,BWB)是指将传统的机身和机翼结构融合的一种新的飞机设计概念。其最早可追溯到20世纪40年代末,但当时的技术无法解决飞机的操纵稳定性问题,所有设计都无果而终。直到B-2轰炸机的问世,才重新引发了设计飞翼客机的兴趣。1988年,NASA的Langley研究中心建立了一个“远程空中运输革命”的项目研究小组,开始探索BWB概念的可行性。90 Blended Wing Body (BWB) is a new concept of aircraft design that blends traditional fuselage and wing structures. As early as the late 1940s, the technology was not able to solve the operational stability problems of the aircraft, all of which were unsuccessful. Until the advent of B-2 bomber, it re-triggered the interest of the design of the aircraft wing. In 1988, NASA’s Langley Research Center set up a project team on a “Remote Air Transport Revolution” to begin exploring the feasibility of the BWB concept. 90
