2014年1月1日 · The recognition spurred aerospace engineers and system architects to come up with the Blended Wing Body (BWB), a new design for next generation aircraft. In this paper, we discuss the development of BWB from the perspective of design challenges that system architects and engineers faced during the design process, the architecting heuristics ...

One of the early comprehensive studies on the BWB was conducted in the late 1990s as a collab-oration among Boeing, NASA, and university partners [6]. It focused on a BWB featuring boundary layer ingesting engines with a passenger capacity of 800, a range of 7,000 nmi, and a cruise speed of Mach 0.85.

2019年8月1日 · By past decades’ investigations the Blended-Wing-Body (BWB) concept has emerged as a potential solution, which can simultaneously fulfill metrics of noise, emission and fuel burn. The purpose of the present work is to analyze the developments of critical technologies for BWB conceptual design from a historical perspective of technology progress.

2024年5月1日 · In the 1990s, a new concept, the blended wing body (BWB), was created to alleviate some of the concerns of flying wings while maintaining increased efficiency and adding further benefits, such as reduced pollutant and noise emissions.

2024年6月20日 · In this study, we explore the history of blended designs from its early days, highlighting its opportunities and challenges—and why the design is an intriguing fit for application as a tanker...

针对基于cfd方法设计的300座级bwb布局概念性方案[3](以下简称bwb-1)，采用风洞试验方法，研究bwb布局的低速气动特性、流动机理及通气发动机短舱的气动特性影响，并验证cfd方法的可靠性。

The first BWB aircraft to be put into production was the Lockheed A-12/M-21 (1962) – this was later developed into the SR-71 Blackbird (1964) – of which 50 were manufactured. In this case, a BWB approach was selected primarily for its ability to deflect incoming radar waves, which, along with other features, made the aircraft nearly ...

Initial Goal: Create a concept for a subsonic transport that may be distinct from tube & wing (DC-8, B707). Initial Result: BWB that offered reduced fuel burn via a very high Lift/Drag ratio and large wingspan. Developed Result: BWB that offers …
