NASA Glenn Research in Controls and Diagnostics for Intelligent Aerospace
Propulsion Systems

Dr. Sanjay Garg
Presented at: ICM 2006, Anaheim, CA

Abstract
With the increased emphasis on aircraft safety, enhanced performance and affordability,
and the need to reduce the environmental impact of aircraft, there are many new
challenges being faced by the designers of aircraft propulsion systems. The Controls and
Dynamics Branch (CDB) at NASA (National Aeronautics and Space Administration)
Glenn Research Center (GRC) in Cleveland, Ohio, is leading and participating in various
projects in partnership with other organizations within GRC and across NASA, the U.S.
aerospace industry, and academia to develop advanced controls and health management
technologies that will help meet these challenges through the concept of Intelligent
Propulsion Systems. This presentation describes the current CDB activities in support of
the NASA Aeronautics Research Mission, with an emphasis on activities under the
Integrated Vehicle Health Management (IVHM) and Integrated Resilient Aircraft Control
(IRAC) projects of the Aviation Safety Program. Under IVHM, CDB focus is on
developing advanced techniques for monitoring the health of the aircraft engine gas path
with a focus on reliable and early detection of sensor, actuator and engine component
faults. Under IRAC, CDB focus is on developing adaptive engine control technologies
which will increase the probability of survival of aircraft in the presence of damage to
flight control surfaces or to one or more engines. The technology development plans are
described as well as results from recent research accomplishments.
