Materials Knowledge Base

ABSTRACT: Development of an operational prototype Test Data Aggregation and Analytical System (TDAAS) at Arnold Engineering Development Center (AEDC). TDAAS will address the customer"s need for data integration and knowledge discovery of Department of Defense (DoD) weapons system engine and flight test data at AEDC. The desired end-state for this project will be TRL 7 at AEDC providing test personnel and facility engineers with improved searching and data correlation capability to better identify and discover knowledge about turbine engine propulsion and flight testing (such as its performance assessment) and anomaly detection (within the test article or the test cell or wind tunnel infrastructure). From this data, AEDC and engine/flight stakeholders will be able to make assessments related to specific component behavior within the systems and comparisons of the data with other system tests for which records exist. BENEFIT: The expected benefits include increasing AEDC"s ability to provide insightful analysis at all stages of an engine and flight acquisition program thus reducing risk while eliminating waste and unnecessary costs that contribute to the USAF and DoD"s longer-term goal to generate greater efficiencies and capabilities ($100B cost savings in the next 5 years). While TDAAS will first be deployed for engine and flight test data, the capabilities themselves are not system or platform specific. The solution envisioned beyond this project could thus be adapted to address data integration and knowledge discovery in satellite health monitoring and other RDT & E applications within DoD, OEMs and other commercial applications.
