Mission reliability assessment for plane fleet based on flight profile

Combat mission of battle plane is usually executed by plane fleet as a unit. Plane fleet can be divided into several team formations. Battle planes in different formations have different flight profiles, and cooperate with each other. The load conditions varied under different flight profiles. According to the influence of load conditions on battle plane´s reliability, the flight profile conversion factor was introduced to establish the reliability model of battle plane. Then, the fault data were utilized synthetically to measure failure rate under each flight profile. On the basis, the mission reliability model of plane fleet was derived. Based on the model, the statistical inference method of mission reliability for plane fleet was put forward using the failure rate under each profile. The illustrative example shows that the method is reasonable and straightforward for engineering.
