A Design Assessment Methodology for Combat Aircraft Operational Effectiveness

In this study a methodology for combat aircraft design will be introduced by using the Unmanned Air Vehicle, U-99, as the case study (Fig. 1). The methodology aims at integration of the survivability assessment into the early stage of combat aircraft design for operational effectiveness. By using the shotline and square counting methods, the vulnerability probability values of the U-99 can be evaluated; and the Reliability Block Diagram has been chosen for developing the flight phase probability in each sortie throughout the mission simulation.
