In vulnerability assessment of aircraft complex systems subjected to traditional weapons, kill tree is used as a visual illustration of the critical components and all component redundancies. This research applies fault tree analysis method in reliability field to analyze the kill tree and determine the minimal cut sets for different kill levels, such as KK, K, A, B and C attrition kill. The tree...
Traditionally, the vulnerability calculation of aircraft subjected to traditional weapon hits by nonexplosive penetrators or missile fragments include two categories. One is exact solution methods (Markov Chain, Tree Diagram) which usually generate large matrix leading to combinatorial explosion problem when aircraft has large amount of redundant components. The other is approximate solution methods...
Traditionally, aircraft vulnerability reductions are considered by fire or explosion prevention of fuel tank, redundant approach, and armor material design, et.al.. This paper proposes a concept of internal component layout optimization to reduce the aircraft vulnerability, so as to achieve the low vulnerability by the natural location shielding or masking among components. In this optimization model,...
