Abstract
The state of the art in the development of the DPDS technique
at the Turbopropulsion Laboratory at the Naval Postgraduate
School is reported. In principle, this method allows
the determination of three dimensional flow fields behind
rotors. A review of the instrumentation and hardware is given
and two different data reduction procedures developed earlier
are described. The results of reducing one set of rotor exit
data using the two methods are compared. In order to verify
the experimental procedures at low cost a bench-top periodic
flow generator was used first to provide signals similar in
type and frequency to those from the Transonic Compressor in
which the rotor exit flow was measured. The data measured in
the compressor were analyzed, and problems encountered in the
routine application of the reduction methods were identified.
The possible application of similar techniques in the Rotating
Annular Cascade (RGG) at the DFVLR Gottingen is assessed and recommendations are made for the coordination of future experimental programs.
