Abstract
The pressure averaging of different pneumatic impact
probes was investigated using a periodic flow generator in
order to establish corrections for probe measurements made
in a compressor, and to guide the selection of probe geometries
to be used in the compressor. The Kulite transducer
probe used as a reference in these measurements was also
used, with both continuous and synchronized sampling, to
measure the flow from the compressor rotor. It v/as concluded
that the corrections required to be made to the pneumatic
impact pressure measurements were negligible at 50% design
speed, but might be significant at higher speeds if the
probe system volume were not properly sized.
