The intense noise generated by military aircraft hans a significant impact on ground crews and their families on airbase. For minimizing the impact of the aircraft noise on the airport, appropriate indoor noise standard is required. This paper studied to establish the indoor noise standard on the military airport. The aircraft noise was measured and analyzed the frequence characteristics. the remodeling of office for the noise mitigation was enforced to verify the appropriate internal noise standard and to select the method of reinforcement. The noise standard was classified three categories according to the dwelling, office and usage of building with flight train facilities and banishment in military airfield.

Gimpo International Airport is a strategically utilized airport based on government policy, but there are many residents living around the airport, so it is very sensitive to changes in airport operation. In the past, similar noise results were obtained for aircraft noise at Gimpo International Airport despite changes in aircraft types and an increase in the number of aircraft operating, and recently ICAO proposed a low-noise aircraft noise standard (Ch.14). Since the new standard has a noise reduction effect of up to 15dB compared to existing aircraft noise, ICAO and Europe EASA predict that future aircraft noise will be reduced if the latest technologies such as low-noise aircraft are applied. Therefore, this study establishes the aircraft operation performance and measured noise of Gimpo International Airport in 2022 as a baseline scenario, noise changes using various scenarios of introduction of low-noise aircraft, operation of mid-to-long-distance routes, and changes in future air traffic demand were analyzed using simulation.

The study show that things about the noise control are indicated at The Noise & Vibration Control Act and the other Act. Also, the details program and total government ministries' program for the noise control are indicated what are the advance noise control plan. The study consist of the four part which are "Draw up the environmental noise infrastructure plan; the install shall be done the noisemap & the automatic noise measurement devices", "Resetting of environmental noise standard at the application area and Introduce of indoor noise; the guide for region classification of the noise standard & indoor noise", "Setting of aircraft noise standard and Program of measurement point operation; the noise-assessment-standard shall change from WECPN to new index($L_{den}$, $L_{dn}$, $L_{Aeq\;24h}$) & the operation and control of aircraft noise measurement changes from local environmental office to central control center" and "The method of noise regulation at construction site and the plan on making of standard for vibration regulation; It shall be made that the guideline of construction noise should include a target-construction, noise standard etc & the ministries shall unify control about construction vibration of the blasting vibration". The advance noise-policy will improve efficiency to deal with civil appeal & damage on residents about noise.

Aircraft noise is the serious problem for inhabitants near an air force base. Noise by ground test of aircraft, however, can be minimized through test room construction. In this study, environmental effects of the noise by aircraft ground test were investigated by experiments under the standard act and by performance, prediction of the Hush house, constructed for the noise reduction.

In an effort to reduce aircraft noise, noise abatement areas are designated and notified, and noise abatement procedures are implemented. However, residents in noise abatement areas are increasingly complaining about the increase in noise, and airlines are exceeding the criteria for noise. In this study, A330-300 airplane set flight conditions that are predicted to generate the most noise when taking off 32 runway at Gimpo International Airport, and predicted the noise as the NPD curve of the INM and AEDT programs. As a result of the analysis, it was considered that the noise at a specific point would generate higher noise than the noise criteria. Therefore, to avoid exceeding aircraft noise criteria at a particular point, supplementing the departure procedures by reflecting aircraft performance under flight conditions would reduce complaints from both airlines and local residents.

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.

After a series of aircraft noise measurements conducted in Noise Sensitive Areas(NSAs) in Gangwha Island, there appeared to be no regions affected by aircraft noise of over 75 WECPNL, the legal noise level standard for aircraft operations. However, with regard to the future environment where flight operations at Incheon International Airport are likely to escalate, an INM analysis result drawn shows that the number of regions afflicted by such noise will increase in Gangwha Island. Therefore, we studied similar cases from developed countries, which are pertinent to solutions for aircraft noise abatement in the vicinity of airports and herewith provided 6 more flight operation procedures other than those 3 currently in service at Incheon International Airport.

현재 항공기 민수인증분야에서 국제적으로 사용하고 있는 항공기 소음인증기준인 ICAO Annex 16 Vol. I에서는 항공기의 종류에 따라 A-Weighted SPL, EPNL, SEL 계산법을 사용하고 있다. 우리나라를 포함한 미국, 유럽도 이를 기반으로 항공기 소음인증기준을 개발하여 사용하고 있으며, KAS 36, CS 36, FAR 36 기준이 모두 동등하고 제한 값은 동일하다. 소형 항공기의 경우에는 이륙소음 한계만 규정하고 있으며, dB(A) 단위의 A-Weighted SPL 계산법을 사용하고 있다. 국내에서는 2012년 8월에 KC-100 항공기에 대하여 소음인증을 최초로 수행한 바 있으며, 당시 FAA와 함께 KAS 36과 FAR 36 해당 기준을 동시에 만족하는지 시험평가 되었다. 소음인증시험의 경우 시험조건과 처리방법이 까다로워 많은 경험과 배경지식이 필요하다. 이에 KC-100 인증비행시험을 기반으로 소형비행기의 소음인증 기준 분석과 시험조건 및 데이터 처리방법을 실 인증사례를 바탕으로 제시하고자 한다.

After analyzing each procedure from standard instrument procedures used at Incheon International Airport, which is believed to have caused noise problems in and around Ganghwa island, we came to a conclusion that some Standard Instrument Departure Procedures and Standard Instrument Approach Procedures need to be revised, and therefore we made some propositions with regard to noise abatement procedures(CDA, RNAV approach etc.). Additionally, we evaluated viability of the proposed flight procedures by conducting a number of demonstrations with use of flight simulation.

In this paper, fatigue life analysis of each structure was performed through theoretical analysis method at design stage in order to verify the success or failure of the store's acoustic noise durability according to the Method 515.5 standard of MIL-STD-810F. In addition, experimental analysis was carried out through the ground and flight test by manufacturing the measuring store, and verification of the sound durability was completed through the flight test after manufacture of the actual store. Furthermore, the commercial FEM code through the PSD calculation method applying measured SPL enables verify the durability of new store components development for the future.
