Abstract
The objective of this project is to develop and validate improved methodology for the substantiation and the usage-based tracking of rotorcraft dynamic system components. A Helicopter Information Retrieval & Substantiation System(HIRSS) is proposed whichconsists of (1) an Universal Damage Tracking Algorithm(TM) capable of accommodating the different fatigue analysis methodologies of the manufacturers, (2) a flight loads and logistics database management system, and (3) a CAD-based scenario modeler whichallows damage summation scenarios to be constructed using point n'click modeling. With the flight loads DBMS, a scalable flight loads database that can be queried by the damage summation algorithm can be automatically built from flight data tapes. Withthe logistics DBMS, the HIRSS can serve as a base station for processing data from on-board HUMS, and as a maintenance and logistics decision support system. With the scenario modeler, the HIRSS can serve as a methodology development platform, wherebynested multi-level Monte Carlo risk assessments can be set-up or modified, using point n'click modeling, to assess the role of each stochastic driver on the reliability of a member. Availability of the HIRSS can lead to an improved substantiationmethodology for dynamic system components. It can help identify any conservatisms which may lead to the premature or unnecessary removal of components, leading to lower operating costs to fleet operators. Because the HIRSS also allows certifying agenciesto independently corroborate retirement times, it can also
