This report describes the design and construction of a velocity probe calibration rig to be used in future fluids research at Worcester Polytechnic Institute. A high accuracy, automated device was manufactured with the capability of taking flow measurements over a wide range of testing conditions. This instrument was designed to collect low speed airflow measurements from a probe over a range of pitch and yaw angles, with both pressure probes and hot wire anemometers. The major components of this device included a flow channel, probe manipulator, and an axial fan drive system. The probe manipulator was designed to provide greater than 1/10 degree positioning accuracy, and repeatability in fluids experimentation.
