EVALUATION OF AIRFRAME NOISE PREDICTION METHODS

Predictions by Revell's drag element model, and Hardin's total aircraft noise method where applicable, are compared with measured flyover noise spectra for different configurations of a large commercial jet transport, a business jet, a small twin-propeller aircraft, and a sailplane. These two methods had been recommended in the NASA Aircraft Noise Prediction (ANOPP) study. Predictions by a noise component method recently developed at United Technologies Research Center (UTRC) under a contract with FAA also are shown. This new method gives closest agreement with measured flyover spectra. The total aircraft noise method, which applies only for aircraft in the clean configuration, was in poor agreement with measured spectra.
