Modern experiments in fluid mechanics have become increasingly complicated as the demand for computational fluid dynamics (CFD) validation data grows. Test data is now generated from diverse sets of instruments each with their own unique calibration and data processing requirements. Designed for use with multi-hole probes, our micro Air Data System (μADS) has self-contained pressure sensors and onboard real-time data reduction for direct measurements of flow angle, total, and static pressure. The μADS streams data in engineering units to a PC or logs data to onboard memory so there is no need to worry about applying probe calibrations to raw pressure data. Additionally, the μADS can be synchronized with other instruments via an external trigger signal and timestamps are provided with each sample.
