Wide_Operability_Engine_Technology @SRW (Subsonic Rotary Wing)

Fundamental waves:
~ the ability to vary the speed of the rotor by over 50% while maintaining adequate power and efficiencies
~ an integrated gearbox/engine systems approach
~ advanced modeling tools and concepts to allow an engine to achieve a larger speed range without sacrificing power and efficiency
~ engine flow controls for enhanced stall margins
~ combustor technologies and modeling capabilities specific to small geometry propulsion systems
~ advanced cooling methods to enable durable, high power output
~ modeling to understand the effects of atmospheric water and particle ingestion that can inhibit wide operability
~ stall control technology to mitigate detrimental impact of inlet distortions and blade erosion on engine performance
~ alternate flow concepts to allow an engine to run efficiently at different speeds
~ high temperature technologies to allow an engine to produce high power at low speeds
~ fundamental combustion physics will be studied and modeled to address efficiency limits of small engine combustors
~ validation of models and concepts developed will be conducted using engine component and combustion test facilities at GRC
