The Boeing X-48 is an American experimental unmanned aerial vehicle (UAV) built to investigate the characteristics of blended wing body (BWB) aircraft. Boeing designed the X-48 and two examples were built by Cranfield Aerospace in the UK. Boeing began flight testing the X-48B version for NASA in 2007. The X-48B was later modified into the X-48C version, which was flight tested from August 2012 ...

The current study presents a low-fidelity, quasi-3D aerodynamic analysis method for Blended-Wing-Body (BWB) Unmanned Aerial Vehicle (UAV) configurations. A tactical BWB UAV experimental prototype is used as a reference platform. The method utilizes 2D panel method analyses and theoretical aerodynamic calculations to rapidly compute lift and pitching moment coefficients. The philosophy and the ...

2018年2月1日 · There is a number of studies, which examine the BWB geometry as a UAV concept either from a designer's perspective or experimentally. For example, Lehmkuehler et al. [16] present the design and testing of a BWB UAV concept, whereas in [28] an experimental study of a BWB UCAV model is shown, including force balance measurements and …

2021年12月6日 · To best address these issues discussed above, a small DEP-based BWB unmanned aerial vehicle (UAV), as shown in Figure 1, is designed and studied by means of computational fluid dynamics (CFD) and wind tunnel test. It can be seen that the present DEP-based BWB UAV use unique tailless configuration with high-level integration between the wing ...

2021年1月1日 · The current study presents the layout optimization of a tactical, fixed-wing UAV, during the early stages of the preliminary design. The reference platform is a Blended-Wing-Body (BWB) configuration, whose mission is the aerial delivery of cargo and lifesaving supplies.

2022年5月5日 · The current work is an Aerodynamic design study of a Blended Wing Body (BWB) Unmanned-Aerial-Vehicle (UAV). Trade studies are carried out to establish the aerodynamic design parameters based on ...

2022年3月7日 · Panagiotou and Yakinthos studied the BWB in low subsonic and incompressible flow conditions, with the main motive to establish trends and insights into using the BWB for UAV applications. They analyzed the effect of sweep angle of the wing on the BWB and concluded that a sweep angle of 0° was the most efficient one at the said flow regime.

2023年11月6日 · In the development of a blended wing body (BWB) planform for low-speed unmanned aerial vehicles (UAV), the present design approach relies on rather cost-effective fidelity tools in aerodynamic modeling and testing. This enables efficient analysis management of the huge parametric studies from airfoil to wing definitions, and proves thereby to be appropriate for conceptual design. Here ...

2014年1月1日 · The presented BWB UAV design here has achieved an unprecedented capability in terms of sustainability of flight at high angle of attack, low parasite drag coefficient and decent maximum lift ...

A Blended Wing Body (BWB) UAV has several aerodynamic advantages of lower wetted area to volume ratio and lower interference drag as compared to conventional type UAV. This paper is focused on the design of the autonomous flight control system for a BWB UAV. An onboard control system is developed by using a powerful computer, navigation sensors and communication modem. The autopilot of the BWB ...
