External noise analysis of supersonic fighter aircraft MiG-21 UMD

This paper contains overview and analysis of supersonic fighter’s MiG-21 UMD external noise parameters measured during typical aircraft engine power settings in static i.e. on-ground conditions: idle power, maximum continuous power, 1st afterburner stage and 2nd afterburner stage. The research aims to evaluate the noise impact on ground staff while handling supersonic fighter on the tarmac. Assessed data show noise levels well above recommended under all aircraft engine regimes
