Advanced Noise Control Fan Aerodynamic Performance

摘要: Abstract The Advanced Noise Control Fan at the NASA Glenn Research Center is used to experimentallyanalyze fan generated acoustics. In order determine how a proposed noise reduction concept affects fanperformance, flow measurements can be compute mass flow. Since tedious mapping isrequired obtain an accurate flow, equation was developed correlate inlet lipwall static pressure measurements. Once this correlation obtained, for futureconfigurations obtained from non-intrusive wall pressures. known,the thrust and performance evaluated. This enables acoustics performanceto simultaneously without disturbing List of Symbols P absolute pressureP g gauge Pta total Ptg atm atmospheric M mach numberm& m&corr corrected T amb ambient temperature
