Aerodynamic Design Optimization Studies of a Blended-Wing-Body Aircraft
Abstract The blended-wing body is an aircraft configuration that has the potential to be more efficient than conventional large transport aircraft configurations with the same capability. However, the design of the blended-wing is challenging due to the tight coupling between aerodynamic performance, trim, and stability. Other design challenges include the nature and number of the design variab...
متن کاملAnalysis Design and Optimization of Non-cylindrical Fuselage for Blended-Wing-Body (BWB) Vehicle
Initial results of an investigation towards finding an efficient non-cylindrical fuselage configuration for a conceptual blended-wing-body flight vehicle were presented. A simplified 2-D beam column analysis and optimization was performed first. Then a set of detailed finite element models of deep sandwich panel and ribbed shell construction concepts were analyzed and optimized. Generally these...
متن کاملAIAA 2005-2349 Blended-Wing-Body (BWB) Fuselage Structural Design for Weight Reduction
Structural analysis and design of efficient pressurized fuselage configurations for the advanced BlendedWing-Body (BWB) flight vehicle is a challenging problem. Unlike a conventional cylindrical pressurized fuselage, stress level in a box type BWB fuselage is an order of magnitude higher, because internal pressure primarily results in bending stress instead of skin-membrane stress. In addition,...
متن کاملNonlinear Aeroelasticity of a Very Flexible Blended-Wing-Body Aircraft
This paper presents a study on the coupled aeroelastic/flight dynamic stability and gust response of a blendedwing-body aircraft that derives from the U.S. Air Force’s High Lift-Over-Drag Active (HiLDA) wing experimental model. An effective method is used to model very flexible blended-wing-body vehicles based on a low-order aeroelastic formulation that is capable of capturing the important str...
متن کاملDesign and analysis of the control and stability of a Blended Wing Body aircraft
Future aircraft generations are required to provide higher performance and capacity with minimum cost and environmental impact. This fact calls for the design of revolutionary unconventional configurations, such as the Blended Wing Body (BWB), a tailless aircraft which integrates wing and fuselage into a single lifting surface with efficient and promising results. In this paper, a BWB aircraft ...
