SVS Description
The Single-Vector System (SVS) is an augmentation of the standard manual force
balance calibration system, which integrates the use of a single-vector load
application mechanism enabling the capability to easily apply multi-component
loadings to an internal wind-tunnel balance. Through the use of this single-vector
load application mechanism the SVS enables the complete calibration of a force
balance with a series of single force vectors. Calibrated weights are applied in the
gravitational direction, while the angular orientation of the balance is manipulated,
allowing the single load to generate three force and moment vectors with respect to
the balance moment center. By utilizing this single force vector to simultaneously
load multiple balance measurement components, the inaccuracies associated with
the conventional method of generating multiple force vectors are fundamentally
reduced, increasing the confidence in the results. The SVS implements statistical
design of experiments (DOE) techniques through all three major phases of the
calibration experiment; the design of the experiment (load schedule & mechanical
calibration hardware), the execution of the experiment, and the statistical analysis
of the experimental data.
