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. Also the propulsion systems required to enable the NASA future human space exploration activities in an affordable manner will need to have high reliability, safety and autonomous operation capability. The Controls and Dynamics Branch 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 some of the key current activities of the Controls and Dynamics Branch (CDB) under the NASA Aeronautics Research and Exploration Systems Missions. The programmatic structure of the NASA Aeronautics Research Mission is briefly discussed and the new program management structure for Aeronautics Programs is overviewed. The activities covered in the presentation include: i) Recent GRC accomplishment in demonstration of active suppression of combustion instability for a low emission prototype combustor; ii) Research on an enhanced gas path diagnostics architecture which is based on the use of a real-time on-board engine model which adapts to changes in engine condition; iii) Development of a risk assessment architecture to implement enhance engine response control modes for emergency operation.
