| Description |
A methodology for quantifying wind tunnel data quality from repeat tests is described. The methodology largely adopts the measurement uncertainty concepts and statistical analysis techniques recommended by AIAA Standards. Repeatability quality of measurements is quantified in terms of three statistical parameters viz., precision limit (or random uncertainty), tolerance interval and precision interval. A description of the methods used for determining these statistical parameters is given.
A computer program developed to facilitate routine application of the above analysis to repeat test data obtained in the NAL 1.2m and 0.6m wind tunnels is described. To illustrate the application of the above methodology and use of the computer program an analysis of longitudinal aerodynamic data obtained from repeat tests on a typical fighter aircraft model in the 1.2m tunnel has been made. Results of this analysis along with a discussion of the same, and a comparison with similar results obtained on a commercial transport airplane configuration in the NASA 2.5m cryogenic tunnel are included in the report.
