Abstract

Laser transit velocimetry has been used at DRA Pyestock to investigate the internal flow fields of high-speed turbomachinery test rigs. Measurements have been made on a highly loaded core compressor and a multi-stage transonic fan. The data acquisition and analysis systems are described and their use on the rigs detailed. A number of test results are presented along with comparisons between other measurement techniques and the DRA S1-S2 flow calculation method. Various problems encountered are discussed along with ways of overcoming them in the future.
