Revolutionary Vertical Lift Technology Project: Variable-Speed Power Turbine Technology Demonstration

Demonstrate 50% improvement in efficient operational capability using a Variable-Speed Power Turbine concept. To enable this improvement, thermodynamics mechanical challenges from operating across variable shaft speeds must be accommodated. Also, aerodynamics research for the engine high-efficiency turbine component design must be conducted over a wide range of incidence angle variation.
