SwRI Engine Health Management Flyer

About the Cover: SwRI works closely with the U.S. Air Force to provide jet engine health management for various engine models including (from top) F110, TF33, F118, F100, TF39 and F108.

Since 1989, Southwest Research Institute® (SwRI®) has provided jet engine health management solutions for the U.S. Air Force, Army, and original equipment manufacturers (OEM). SwRI is a recognized leader in developing innovative solutions and providing independent engineering assessments, including:

SwRI's success in EHM is based on a multidisciplinary systems engineering approach to problem solving. Comprehensive expertise in design, modeling and integration enables SwRI to address client needs.

SwRI has implemented an AS9100 Quality Management System for all design and manufacturing processes, including engineering analysis tasks and software development.

SwRI develops and delivers ET&D training to USAF engine maintainers.

Working closely with the U.S. Air Force, SwRI supports EHM+ to reduce engine maintenance, repair and overhaul costs and engine downtime. ET&D uses historical engine performance and maintenance data to develop trends that are used to determine engine performance and identify potential engine failures before they occur. EHM+ uses ET&D and Reliability Centered Maintenance (RCM) concepts to improve performance. EHM+ data is warehoused and accessible over the Internet.

SwRI engineers use their operational understanding of engine control systems, sensors and signals, and engine trending software to develop engine performance analysis methodologies for the following engines:

F100
F101
F108

F110
F118
T56

TF33
TF34
TF39

Development of the methodologies requires research of engine parameters and their correlations, and review of maintenance that affects engine performance trends. The methodologies are documented in Technical Orders that instruct USAF personnel on how to trend and analyze a specific type/model/series engine.

F100
F101

F108
F110

TF33
TF34

SwRI works closely with the USAF Air Education and Training Command (AETC), other MAJCOMs, USAF engineers and OEMs to develop the courses, following the Air Force Instructional System Design (ISD) process, and transfers the course material for AETC to continue providing the training after the first year of delivery by SwRI. Course content includes relationships of engine parameters, trending concepts and terminology, and use of available software tools to perform EHM+ related job duties.

EHM+ tools provide users with the ability to quickly assess aircraft engine health.

EHM+ tools display performance parameter trends for a single engine.
