Aircraft Noise Definition. Phase 1. Analysis of Existing Data for the DC-8, DC-9 and DC-10 Aircraft
Abstract
The efforts in this phase of the 'Aircraft Noise Definition' project was comprised of processing and analysis of existing acoustic and performance data and preparing acoustic and performance (based on average engine) graphical and computer presentations for two JT3D turbofan-powered DC-8s, one with short and one with long fan ducts; two DC-9s, one with JT8D-7 and one with JT8D-9 engines; and the DC-10-10 and DC-10-40 aircraft. The acoustic data included reference-day EPNL and peak A-weighted sound level curves with empirically developed curves for adjusting the noise levels to temperatures from 30 deg F to 100 deg F with the relative humidity held constant at 70 percent. The performance data include provisions for a temperature variation from 30 deg F to 100 deg F and runway altitude from sea level to 6000 feet. Data accuracy is described in terms of assignable confidence limits.
