Preliminary Measurements and Code Calculations of Flow through a Cascade of DCA Blading at a Solidity of 1.67.
Abstract
An experimental program to obtain uniform inlet flow to the test blading in a large cascade facility designed to use inlet turning vanes, and to measure the conventional blade element performance, is described. Attempts to reduce non-uniformities (+ or - 1% in velocity) using screens were unsuccessful and so abandoned. Preliminary Double Circular Arc(DCA) blade element performance data were obtained without screens at one incidence angle before aero-mechanical problems with the inlet guide vane assembly curtailed testing. The blade surface pressure distribution at the one test condition compared very favorably with the distribution predicted using the NASA computer code QSONIC. Recommendations were made that would avoid the aero-mechanical problems encountered.
