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...

Aerodynamic Shape Optimization of Wing and Wing-Body Configurations Using Control Theory

This paper describes the implementation of optimization techniques based on control theory for wing and wing-body design. In previous studies [18, 19,221 i t wasshown that control theory could be used to devise an effective optimization procedure for airfoils and wings in which the shape and the surrounding body-fitted mesh are both generated analytically, and the control is the mapping functio...

RANS-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...

An Aerodynamic Data System for Small Hovering Fixed-Wing UAS

Small fixed-wing UAS that are able to hover combine the station keeping abilities of a rotary wing platform and the extended range of conventional aircraft. Current autopilots for these vehicles rely on inertial measurements plus airspeed to transition from forward flight to hover, accumulating appreciable position error during the transition. Once in hover, a combination of inertial and GPS da...

Aerodynamic Optimization of Transonic Wing Design Based on Evolutionary Algorithm

Evolutionary Algorithm (EA) is applied to a practical three-dimensional shape optimization for aerodynamic design of an aircraft wing. Aerodynamic performances of the design candidates are evaluated by using the three-dimensional compressive Navier-Stokes equations. A structural constraint is introduced to avoid an apparent solution of zero thickness wing for low drag in high speeds. To overcom...
