Abstract : This technical note consists of two separate papers. The first covers the compressible calibration of the seven-hole probe and is a reprint of an article in the Aeronautics Digest - Fall/Winter 1980, USAFA-TR-81-4. The second paper describes the associated software for the data acquisition system and contains program listings. Together, the two papers describe the entire data acquisition system developed to measure flow field properties quickly and economically in wakes using the seven-hole probes.
