SBIR-STTR Award

Steady-state and transient control modes for extending aircraft engine life will be defined and evaluated to determine their effectiveness in a typical military engine program. The steady-state modes will include an approach which adds temperature compensation to existing controls and a model-based control approach which operates the engine at the minimum high pressure turbine inlet temperature for the selected thrust level. The transient mode uses stator reset to minimize the transient temperature rise. The proposed program will define each mode and estimate its potential for extending engine life. The most attractive concepts will be identified for further development in a subsequent program
