  • 항공기의 성능 개선이나 관련 법규의 요건 만족을 위해 항공기 시스템 개조는 필요하다. 이러한 개조를 위해 기술력이나 항공기의 감항성을 위한 설계 검증, 형식 증명에 대한 부가형식증명(STC)의 인증 절차는 적절한 표준이 요구된다. 본 연구는 국내 항공기 개조 현황과 수요를 분석하고 현재의 부가형식증명 절차를 검토하여 그 문제점을 진단한다. 또한 늘어난 항공기의 수명에 대하여 개조기술 및 인증 능력 향상방안을 연구한 결과 개조 조직의 인가와 분야별 전문 엔지니어 자격 임명 그리고 교육 체계 개선이 요구되었고 국내 부가형식증명 절차의 개선을 도출하였다.

  • In order to export aircraft components or substructures, it is necessary to get a certification from the main company for the components or an airworthiness certification from the FAA. In Korea, those processes are performed by a small number of private companies for aircraft components. However, airworthiness certification has never been done in the company. To export an assembled aircraft, whether small or large, it is obligatory to get a certification for the aircraft being exported. Currently, the Korean government is trying to get BASA agreement in a few years. For a mid-size company, it is easier to get the NADCAP audit process for the supply of aircraft components to the main company. In this paper, the overall process of aircraft certification is discussed and airworthiness certification is treated for export aircraft. Moreover, the NADCAP audit process is described in detail by introducing example parts made of composite material. This detailed process would be very helpful to a small or mid-size company that wants to develop and deliver aircraft components to foreign companies.

  • Airworthiness certification is a repeatable process implemented to verify that a specific aircraft can be safely maintained and operated within its approved flight envelope. Airworthiness certification activity for the FA-50 aircraft has been performed according to the Airworthiness Certification Criteria, issued in 2011 by DAPA. It is a right time to study the application of those existing ACC process and tools to the hypothetical modification aircraft. This paper describes airworthiness engineers view of the integrated activities required to substantiate the modified aircraft performance. The compliance methods applicable to the airworthiness certification criteria is also suggested. It will be useful for the establishment of the future Korea modified military aircraft's ACC with the risk assessment and methods of compliances tailored to the legacy aircraft.

  • 러시아 정부는 세계 3위의 민간항공기 생산 강국을 목표로 민간항공기 제작기술 및 첨단 소재 확보를 위해 외국과 생산 제휴 등 전략적 협력을 확대하는 중이다. 또한 러시아 정부는 항공기 제작산업의 발전을 지원하고 항공 인증 조직을 개편하여 체계적인 항공안전 확보를 추구하고 항공제품 수출을 위한 국제협력과 인증활동에 많은 노력을 기울이고 있다. 국가 간에 민간항공기 안전 및 인증분야의 협력체계를 구축하기 위해서는 전반적인 인증시스템에 대한 상호간의 이해와 신뢰를 구축하는 과정이 요구된다. 따라서 본 연구에서 러시아의 항공기 인증조직, 법령체계, 인증절차를 분석하여 러시아의 항공기 인증체계에 대한 이해를 돕고자 하였다.

  • Reliability of fatigue strength on Aircraft Composites(GFRP) Structures was assessed in this paper. Fatigue strength of GFRP was used through the existing fatigue test data with Monte Carlo method. The Sa-Nf curve of composites fatigue strength was assumed as normal distribution and reliability was analyzed using SSIT model. Fatigue stress was designed IAW ASTM F3114-15 with special safety factor of Ssf=1.2~2.0. Reliability was calculated by analytic method and FORM. Sensitivity for the effect of mean and standard deviation of fatigue strength as well as fatigue stability was evaluated. This result can be usefully applied to reliability and fatigue design for composite structures of light weight aircraft.

  • In this paper, a conceptual design process for Very Light Jet aircraft has been proposed incorporating aircraft safety certification. During the proposed design process, satisfaction of the airworthiness certification for an intermediate resulting aircraft configuration is evaluated and then redesigns are carried out if necessary and until the designed aircraft configuration satisfies the airworthiness requirements. Certification database has been developed using FAR 23, AC 23, KAS 23, and CS 23 as the airworthiness certification. Based on the developed certification database Design Certifcation Related Table has been produced to use the airworthiness requirements as design constraints in the propsed design process. Using Quality Function Deployment the design variables for a redesign are carefully selected and a design optimization is performed. To demonstrate the feasibility and effectiveness of rapid aircraft conceptual design using the proposed approach, a Very Light Jet design optimization including a redesign of wing flap has been performed and the design results have been presented.

  • The materials applied to the aircraft fuselage, parts, and components must be verified by relative authorities in accordance with the procedures set by the airworthiness authority to achieve the aircraft type certification. There are no examples of domestic composite materials which were verified in order to be applied to aircraft structure. In this study, the composite material certification system of NCAMP, an American composite material standard certification organization, was reviewed and used as the fundamentals of the first aerospace composite material certification system in ROK(Fig 2,8). Also updated material certification documents were developed and confirmed by material certification engineers and inspectors. This aerospace composite material qualification system is intended to modernize the material certification system for AAM(Advanced Air Mobility) as well as aircraft and to enhance the understanding of related technicians and inspectors.

  • 항공기의 개발에 있어 비행시험은 통상적으로 크게 민간용과 군용의 두 분류로 나눌 수 있다. 민간용 항공기의 비행시험은 해당 정부의 감항당국에서 제시하는 안전/성능 요구도를 항공기가 충족하는지 여부를 개발자가 확인하는 것이다. 이에 반해 군용항공기의 비행시험은 소요제기를 한 해당 정부의 요구도를 항공 기기가 충족하는지 여부를 개발자의 사전점검(DT: Developmental Test) 이후에 정부의 독립적인 평가팀에 의해 Operational Test(OT)가 수행되어 최종적으로 확인하는 과정으로 진행된다. 이 논문에서는 민수용 항공기와 군용항공기 각각의 목적상 추진되던 인증업무가 비용의 효율성 제고, 민간항공기의 군용화 추세에 따라 민간항공기 인증방안을 사용해 군용항공기의 감항인증을 추진하는 선진국의 최신동향을 살펴보고 국내의 여건 및 향후 발전발향을 제시하고자 한다.
