Abstract: Automated assessment and forecasting of aircraft health status has become a prime requirement for safety, reliability, and cost streamlining for 21st century's aviation sector. Presently, a variety of flight data, functionality, performance, and maintenance information are being collected and some are stored in databases, but an integrated health management (HM) system that utilizes all these information is virtually nonexistent. Qualtech Systems, Inc. in collaboration with Aptima, Inc. proposes developing an integrated multi-source data acquisition and analytic solution for facilitating diagnostics and prognostics, and providing decision support for operations, maintenance, logistics, supply chain, and military flight quality assurance related processes. Intelligent agent-based techniques will be used for gathering data from heterogeneous sources. Multi-disciplinary analytic techniques including signal processing, time-series-analysis, multivariate statistics, and probabilistic decision fusion, coupled with dependency model-based techniques are envisaged for the HM solution. An optimal decision-oriented user interface will satisfy information dissemination and visualization requirements. Preliminary theoretical development will involve a limited number of simulated data sources from a target naval aircraft. Software implementation and deployment of the solution on the target platform will be performed in subsequent phases of the work. The resultant integrated and flexible HM solution will have applicability across various military and commercial platforms.
Benefits: The proposed effort will maximize utilization of information (e.g., flight test, analytic, health and maintenance data) collected from naval aircraft for the purpose of health management and streamlining of operational and maintenance costs. The agent-based data acquisition system is capable of acquiring information from various types of storages (on- equipment flash memory, different types of databases, electronic documentation, etc) and thus will be compatible for both legacy aircraft and the new generation aircraft equipped with autonomic logistic systems. The analytic part of the health management (HM) solution is capable of not only detection and identification of faults, it will provide health and reliability forecasts along with remaining life time estimates of aircraft equipment/subsystems so as to aid the maintenance, logistics, and flight quality assurance processes. Being web-based, the resulting integrated HM solution will not require dedicated instrumentation for deployment. The decision-oriented user interface facilitates selective information dissemination; which, in one hand furnishes requisite information to appropriate people and in other hand ensures security of the system. Additionally, with very little customization within the analytic part, can make this solution deployable over a variety of air platforms. All military aviation wings (e.g., air force, navy and army) are the envisioned primary beneficiaries from this effort. The technology can be transitioned to the commercial aviation sector with no or very little modification. As these data acquisition, analytic and information dissemination techniques are founded on generic algorithms and approaches, the solution can be deployed to other transport and vehicular platforms such as war ships, submarines, modern military ground vehicle and luxury passenger liners that employ extensive health and condition monitoring schemes.
