The MERIT program, funded by the USAF Wright Laboratory, addresses the need for improved early definition of equipment environmental life cycle profiles. A computer system has been developed as a stool to aid engineers in defining all activities during an equipment item's life and the environments which the equipment will experience during those activities. The system will predict environments using embedded engineering algorithms (i.e., models). The current focus of MERIT is external stores (missiles, pods, bombs) carried by fighter/attack aircraft. This paper describes predictive models for captive flight acoustic noise and vibration environments during aircraft straight and level flight. Results of predictions provide a more detailed representation of measured flight data than that possible in MIL-STD-810E.
