A number of total-pressure tubes were tested in a nonstaedy flow generator in which the fraction of period that pressure is a maximum is approximately 0,8, thereby simulating turbomachine-type flow conditions. The tests were performed at a pressure level of 10(power 5) Pa (1 bar), for Mach numbers up to near 1, and frequencies up to 3 kHz. Most of the tubes indicated a pressure which was higher (P ind/P ind true up to 1,06) than the true average. Organ-pipe at discrete frequencies. resonances which further increased the indicated pressure were encountered within the tubes at discrete frequencies There was no obvious combination of tube diameter, length, and/or geometry variation used in the tests which resulted in negligible averaging error.
