Research on UAV Mission Reliability Flying Test Method Based on Mission Profiles

This paper focuses on the current situation of limited flight test frequency and duration for UAVs, as well as the continuous improvement of reliability during flight test. It analyzes the issues with using mean time between critical failures (MTBCF) for mission reliability validation. Through research on the mission profiles and mission execution of UAV, it proposes a mission success criterion based on mission profiles and operational requirements for UAV. It constructs a method for determining the minimum number of flight test missions based on binomial distribution and establishes flight test verification requirements for mission reliability of UAV.
