aerodynamic shape optimization of supersonic projectile fins

the aim of this work is to find an efficient aerodynamic-based design algorithm for projectile fins and configuration shape optimization. three-dimensional supersonic flow over a projectile with fins at much number 5 and one degree angle of attack was studied. the runge-kutta method and multi-block technique was used to solve the governing equations. a basic configuration was assumed for the fi...

Adjoint-Based Aerodynamic Optimization of Supersonic Biplane Airfoils

This paper addresses the aerodynamic performance of Busemann-type supersonic biplanes at both design and offdesign conditions. An adjoint-based optimization technique is used to optimize the aerodynamic shape of the biplane to reduce the wave drag at a series of Mach numbers ranging from 1.1 to 1.7, at both acceleration and deceleration conditions. The optimized biplane airfoils dramatically re...

Multiobjective Aerodynamic Optimization of Supersonic Wings Using Navier-Stokes Equations

The design optimization of a wing for supersonic transport by means of Multiobjective Genetic Algorithm (MOGA) is presented. The objective function is to minimize the drag for transonic cruise, the drag for supersonic cruise and the bending moment at the wing root for the supersonic condition. The wing shape is defined by planform, thickness distributions and warp shapes, in total of 66 design ...

AIAA 2002-2838 Aerodynamic Shape Optimization for Supersonic Aircraft

Introduction onsidering the remarkable developments in many high technology fields during the past few decades, it is surprising that virtually no change in the speed of commercial air transportation has occurred since the introduction of the Boeing 707 in the late 1950s. Instead, the aging Concorde continues to fly at supersonic speeds for an extremely limited market and all other commercial a...
