Mission Impact and Readiness Assessment Tool for Critical Transmission Assemblies

Impact Technologies with its OEM partner Boeing, proposes to use a combination of newly developed technologies and leverage existing technologies to develop a comprehensive software suite that will assist the Navy personnel in accurately and quickly assessing the impact of actual aircraft usage on critical transmission components and therefore, on overall reliability and mission readiness. It is not uncommon to have the aircraft experience the mission mix in actual use that is significantly different from the mission mix anticipated during the design stage. A different mission mix would therefore mean a potentially lower reliability and mission readiness at any given time. It is critical that tools are available than can accurately assess effects of such deviations on individual tail-number basis as well as at the fleet level. The innovations in this proposed effort will include: a) A graphical drag-and-drop system-level modeling tool to represent multiple failure modes for multiple components in complex transmission systems, b) Computation of individual component damage rates and therefore associated reliability using system level inputs such as the flight regime definitions, c) A reliability roll-up of different components in a “transmission chain” with due consideration to serial and parallel paths and interdependencies.
