Aircraft Reliability Evaluation Method Based on Multi-mission Profile

Aircraft mission reliability is an important indicator to measure its operational capability, which is of great significance to the aircraft’s ability to perform tasks. This paper establishes a mission reliability evaluation method based on operational requirements for the three main factors that affect flight altitude, speed and acceleration, and calculates the flight profiles of multiple mission profiles to obtain the aircraft’s mission reliability, At the same time, the influence of the difference of flight profile on the reliability is considered, which has guiding significance for the reliability evaluation of subsequent aircraft missions.
