Numerical Aircraft Design Using 3-D Transonic Analysis with Optimization. Volume I. Executive Summary.

Abstract : This executive summary volume is divided into two parts: Part 1 highlights the transport development, and Part 2 highlights the fighter development. There are two other volumes which make up the final report. Volume 2 is the main volume in the final report. It presents in detail the information that has been highlighted here. Volume 2 is also divided into two parts with part 1 dealing with transport design and part 2 concerned with the fighter design. Volume 3 is a detailed user's guide to the computer programs produced under this contract. Volume 3 is similarly divided into two parts. A detailed summary of the work performed in the Advanced Transonic Technology (ATT) program to incorporate 3-D Transonic computational aerodynamics methods into aircraft design procedures is presented. Existing transonic analysis programs were modified for the design procedure and linked with a numerical optimization program to design wings that are in some sense optimized for a given set of design conditions. The design procedure was validated by applying it in two design case studies. The application of the design procedure in each of these case studies is described in detail. The configurations resulting from these studies were subjected to design verification wind tunnel testing. Comparisons of test data with computed results are presented.
