Quantitative Measurements of the Effects of Variations in Panel Density and Distributions for Panel Method Computer Programs

Abstract

Panel distributions have been characterized independently in terms of computable and controllable parameters. Thus, a methodology has been developed which will permit a conclusive establishment of the sensitivities of paneling parameters to aerodynamic estimation quality for a wide variety of paneling codes. It has been demonstrated that the global performance (input-output relationships, precision, and accuracy) of a panel method computer program can be established through calibration. Application of the sensitivity analysis developed herein to SURAIR (a Woodward constant pressure panel method derivative) has shown that it is possible to increase estimation accuracy without the commonly expected increase in computation cost.
