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 کاملRANS-based Aerodynamic Shape Optimization of a Blended-Wing-Body Aircraft
A series of RANS-based aerodynamic shape optimization for an 800-passenger blended-wing-body aircraft is performed. A gradient-based optimization algorithm and a parallel structured multiblock RANS solver with Spalart–Allmaras turbulence model are used. The derivatives are computed using a discrete adjoint method considering both frozen-turbulence and full-turbulence assumptions. A total of 274...
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 ...
متن کاملDesign of a 450-passenger blended wing body aircraft for active control investigations
ACFA 2020 (active control for flexible aircraft) is a collaborative research project funded by the European Commission under the seventh research framework programme. The project deals with innovative active control concepts for 2020 aircraft configurations like the blended wing body (BWB) aircraft. The main objectives of ACFA are the design of a new ultra efficient 450 passenger BWB type aircr...
