Abstract

The invention discloses an aircraft reliability evaluation method based on an assembly outline and a fault list. The aircraft reliability evaluation method includes the steps: calculating the actual reliability index observation values of four items, including the average fault interval time MTBF, the average fault interval flight time MFHBF, the success probability MCSP of task completion and thetask time MTBCF between the fatal faults according to the actual condition of the aircraft from entering the test flight station to the delivery period and the assembly outline of the process compilation; and comparing with the designed and shaped minimum acceptable value to obtain a reliability evaluation result, thus conducting reliability evaluation of the aircraft.

Description

technical field

[0001] The invention belongs to the technical field of aircraft reliability evaluation, and in particular relates to an aircraft reliability evaluation method based on assembly outlines and trouble sheets. Background technique

[0002] Modern high-tech aviation equipment adopts a large number of new technologies and methods, and its performance is continuously improved, but its complexity is also greatly increased. Therefore, the problems of reliability, maintainability, testability, support, safety, and environmental adaptability are also brought about. increasingly obvious. For modern aviation equipment, the requirements of six performance indicators and performance indicators are equally important, and have had a significant impact on improving the combat effectiveness of equipment, improving the success rate of missions, and reducing costs.

[0003] In 1993, the Commission of Science, Technology and Industry for National Defense promulgated the "Interim ...
