Wind tunnel engineers require measurements of position and orientation of aerospace models under test conditions. The measurement technique must be non-contact, non-intrusive and have a high sample rate. Videometric techniques based on multiple, synchronized CCD cameras can supply position and orientation data at 30Hz or 60Hz with acceptable accuracies. This paper describes a data acquisition system designed and implemented at NASA Langley Research Center to capture the position and orientation of free-flight aerospace models. System calibration and data processing techniques are discussed. Two examples of model tests will be described and examples of data output will be presented.

“…Wind tunnel testing can also be used to assess the effect of aircraft modifications or various weapons loads, or suggest configuration changes to improve spin recovery. Video camera systems have been used to provide 6DoF data for model testing in the spin tunnel at LaRC since the 1990s (Snow et al, 1992;Shortis and Snow, 1997).…”

ABSTRACT:Aerospace engineers require measurements of the shape of aerodynamic surfaces and the six degree of freedom (6DoF) position and orientation of aerospace models to analyse structural dynamics and aerodynamic forces. The measurement technique must be noncontact, accurate, reliable, have a high sample rate and preferably be non-intrusive. Close range photogrammetry based on multiple, synchronised, commercial-off-the-shelf digital cameras can supply surface shape and 6DoF data at 5-15Hz with customisable accuracies. This paper describes data acquisition systems designed and implemented at NASA Langley Research Center to capture surface shapes and 6DoF data. System calibration and data processing techniques are discussed. Examples of experiments and data outputs are described.
