초록

항공기의 비정상적인 착륙 상황에서도 조종사의 생존을 보장하고 탈출에 방해되지 않도록 구조물이 설계되어야 한다. 추락 시, 화재의 원인을 찾는 연구를 시작으로 과거 수많은 고정익 항공기 추락시험이 수행되었다. 동역학적 분석을 통한 구조물의 거동특성을 이해하고, 가속도 상태에서 인체의 허용한계를 조사하여 적절한 추락하중배수가 설정되었다. 또한 화물기 사고 데이터를 확률론적 방법으로 분석하여 승객의 안전과 운용비용이 합리적으로 반영된 화물고정용 추락하중배수도 제시되었다. 과거 사례를 바탕으로 현재 적용되고 있는 추락하중배수의 물리적, 의학적, 경제적 의미를 살펴 보았다.

When an abnormal landing occurs, aircraft structures should be designed to guarantee occupants survivability without preventing egress. To find out fire root causes at crash, lots of fixed aircraft crash tests were conducted. Appropriate crash load factors were established with the comprehension of structural behavior based on dynamic analysis and investigation of human tolerance. Cargo restraint criteria were set up considering passengers safety and operational cost while analyzing past cargo aircraft accident data using a probabilistic approach. Reviewing results of past crash tests, current crash landing load factor was appreciated physically, medically, and economically.
