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 کاملIntegration of Propulsion-Airframe-Aeroacoustic Technologies and Design Concepts for a Quiet Blended- Wing-Body Transport
This paper summarizes the results of studies undertaken to investigate revolutionary propulsion-airframe configurations that have the potential to achieve significant noise reductions over present-day commercial transport aircraft. Using a 300 passenger BlendedWing-Body (BWB) as a baseline, several alternative low-noise propulsion-airframeaeroacoustic (PAA) technologies and design concepts were...
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 کاملPreliminary Design of a Blended Wing Body Configuration using the Design Tool PrADO
New, unconventional aircraft configurations like the blended wing-body (BWB) are expected to significantly improve the economic efficiency of future air-transport. In order to investigate potential improvements and to predict major design challenges of this new class of aircraft the modelling and analysis capabilities of the in-house aircraft design tool of the IFL, PrADO, have been adapted to ...
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,...
