Wind Tunnel Strain-Gage Balance Calibration Data Analysis using a Weighted Least Squares Approach

Autor: Thomas Volden, Norbert M. Ulbrich

Publikováno v: 33rd AIAA Aerodynamic Measurement Technology and Ground Testing Conference.

A new approach is presented that uses a weighted least squares fit to analyze wind tunnel strain-gage balance calibration data. The weighted least squares fit is specifically designed to increase the influence of single-component loadings during the

A Universal Threshold for the Assessment of Load and Output Residuals of Strain-Gage Balance Data

Autor: Norbert M. Ulbrich, Thomas Volden

Publikováno v: 55th AIAA Aerospace Sciences Meeting.

A new universal residual threshold for the detection of load and gage output residual outliers of wind tunnel strain{gage balance data was developed. The threshold works with both the Iterative and Non{Iterative Methods that are used in the aerospace

A New Load Residual Threshold Definition for the Evaluation of Wind Tunnel Strain-Gage Balance Data

Autor: Norbert M. Ulbrich, Thomas Volden

Publikováno v: 54th AIAA Aerospace Sciences Meeting.

A new definition of a threshold for the detection of load residual outliers of wind tunnel strain-gage balance data was developed. The new threshold is defined as the product between the inverse of the absolute value of the primary gage sensitivity a

Evaluation of Regression Models of Balance Calibration Data Using an Empirical Criterion

Autor: Thomas Volden, Norbert M. Ulbrich

Publikováno v: 28th Aerodynamic Measurement Technology, Ground Testing, and Flight Testing Conference.

An empirical criterion for assessing the significance of individual terms of regression models of wind tunnel strain gage balance outputs is evaluated. The criterion is based on the percent contribution of a regression model term. It considers a term

Regression Model Term Selection for the Analysis of Strain-Gage Balance Calibration Data

Autor: Thomas Volden, Norbert M. Ulbrich

Publikováno v: 27th AIAA Aerodynamic Measurement Technology and Ground Testing Conference.

The paper discusses the selection of regression model terms for the analysis of wind tunnel strain-gage balance calibration data. Different function class combinations are presented that may be used to analyze calibration data using either a non-iter

Development of a User Interface for a Regression Analysis Software Tool

Autor: Norbert M. Ulbrich, Thomas Volden

Publikováno v: 48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition.

An easy-to -use user interface was implemented in a highly automated regression analysis tool. The user interface was developed from the start to run on computers that use the Windows, Macintosh, Linux, or UNIX operating system. Many user interface f
