Research Institution
Propulsion system components are being exposed to increased thermal and aerodynamic loads. Active stabilization of these components is considered one of the key technologies required to enhance the oeprability of gas turbine engines. Recently there have been numerous successful demonstration of active control to alleviate compressor surge and rotating stall. Almost all of these active surge/stall controls have been proof-of-concept studies on laboratory-scale compressors or engines. A compelling need arises which is to evaluate all reported and new methods of active surge/stall control and to select the most feasible method for full engine demonstration. Scientific Monitoring, Inc. proposes to conduct a program of research on surge and rotating stall controls for turboshaft engines. Particularly, the research will emphasize a systematic trade study of various control methods and actuator/sensor combinations. The firm is also interested in investigating the effects of distortion and tip clearance on active surge/stall control. The research will use Textron Lycoming T53 engine as the baseline for feasibility evaluation.
