Abstract

The aircraft noise analysis area in this study is a training airfield where various kinds of aircraft are operated. It is difficult to identify the noise analysis as a real measurement in a training airfield. In order to overcome these practical limitations and to establish appropriate noise countermeasures, a noise map is prepared using the Integrated Noise Model Version 7.0 of the aircraft noise prediction program used by the FAA. The noise of C90GT aircraft was measured while flying the takeoff route, landing route, and long route. We want to identify areas where noise damage is more than 70 WECPNL. No area exceeding the legal standard of 70 WECPNL was found in all routes.

여러 종류의 항공기가 운용되고 있는 훈련 비행장에서 항공기의 소음을 실제 측정하여 분석하는 것은 어렵다. 이러한 실제적인 한계를 극복하고 적절한 소음 대책을 수립하기 위해서 FAA에서 사용하는 INM 7.0(Integrated Noise Model Version 7.0)을 사용하여 소음 지도를 작성하였다. 터보프롭 항공기 (C90GT)가 이륙 경로, 착륙 경로 및 장주경로를 비행하면서 발생하는 소음을 측정하였고 법적으로 소음의 피해가 되는 70 WECPNL 이상인 지역을 조사하였다. 터보프롭 항공기가 운용되고 있는 모든 경로에서 70 WECPNL을 초과하는 지역은 발견되지 않았다.
