Improving the Capability of Preliminary Aircraft Design Methodology by Incorporating Numerical Methods into Segments of a Proven Statistical Method

<p>The purpose of this study was to identify any potential limitations of Roskam’s statistical aircraft flight performance estimation method, and to provide processes capable of improving those limitations. This project was conducted in collaboration with Diamond Aircraft Industries, and as any other general aviation manufacturer with limited time, manpower, and financial resources, Diamond wants the new process to be time and cost-effective. Presented in this study is a computational alternative that combines the speed and accuracy of low-order panel methods with the fully-coupled viscous/inviscid interaction method from the ISES code that was developed by Drela and Giles. Its benefit is the ability to optimize aerodynamic parameters that are ignored by statistical methods, such as multiple taper ratios, aerodynamic and geometric twist. Most notably, cost of this method is dramatically reduced by separating the computational domain into a separate one for lifting surfaces and one for fuselages.</p>
