    Presentation and Development of Aerocraft Operational Integrity by HE Yuting

    Published 2022-06-01
    “…Aerocraft operational integrity(AOI)can be used to show the quality attribute of aircraft in the operational processes more comprehensively.Firstly,the concept presentation process of equipment operational integrity(EOI)is introduced,and the basic connotation and characteristics of AOI is discussed.The AOI which is the basis of usability and efficacy elaboration is expounded.Then,three characterizing parameters of AOI are introduced,including aircraft inherent readiness rate,aircraft inherent healthy degree,and aircraft operational integrity degree,and the primary optimum design method of AOI is discussed.Finally,the control principle of AOI is proposed,and the foundation and research methods of AOI which are the urgently necessary directions of AOI development and research in aeronautical and astronautically fields in our country are pointed out.…”
