• Abstract:
  A computer program to predict the Effective Perceived Noise Level (EPNL), the tone corrected Perceived Noise Level (PNLT) and the A-Weighted Sound Level (dBA) radiated by a V/STOL vehicle as it flies along a prescribed takeoff, landing, or cruise flight path is described in detail and a complete users guide for the program is presented. The procedure used to predict the noise radiated by helicopter rotors, propellers, turbo shaft engines, lift and cruise fans, and jets are described in detail. Helicopter rotor noise and jet noise are theoretically predicted with some empirical modifications while propeller, fan and turboshaft engine noise is calculated with primarily empirical procedures. The program is designed to be easy to use; thus it should be useful in V/STOL-port planning studies
