Case Study of F-15 Airframe Battle Damage Repair Design and Assessment Procedure

F-15 기체 전투손상 수리설계 및 평가기법 사례연구

  • Published : 2009.01.01

Abstract

For the purpose of facing battle damage that a fighter is subject to in combat, following recovery procedures such as damage assessment, repair design and structural integrity evaluation are investigated. A sample study is presented on the battle damage of F-15 ECS bay, which is comprised of damage assessment and repair design based on ABDR(Aircraft Battle Damage Repair) skills and work procedure complying with AFTO(Air Force Technical Order) forms. Further, the flight safety of repaired structure is validated and the time the permanent repair should be done is estimated through the evaluation of structural integrity such as the calculation of static strength and fatigue life.

전투기가 임무수행중 기체에 발생할 수 있는 전투손상에 대처하기 위해 손상평가 및 수리설계, 구조건전성 평가방법 등 손상 후속절차를 연구하였다. 사례로서 F-15 ECS Bay에 발생한 전투손상에 대하여 ABDR(Aircraft Battle Damage Repair) 기술을 적용하여 손상평가 및 수리설계를 수행하고, 그 내용과 절차를 양식에 정리하였다. 또한, 정적강도 및 피로수명 계산과 같이 수리설계 구조의 구조건전성을 평가하여 비행안전 여부를 입증하고 영구수리 시점을 판단하였다.
