Advanced Variable Speed Power Turbine (AVSPOT)
Abstract
Current and future US Army rotorcraft will rely on significant technological advancements to deliver improved performance capabilities to the future warfighter of tomorrow. One critical needed technology is an advanced variable speed power turbine (AVSPOT) design. A robust power turbine (PT) design, capable of high-efficiency operation between 55-105% speed provides a versatile power system that is compatible with the types of future rotorcraft configurations that are currently being studied for Future Vertical Lift (FVL) applications. The AVSPOT Program successfully matured incidence tolerant airfoil design methodologies required for efficient wide speed PT operation. This report details the aerodynamic and mechanical design of the variable speed PT concept and the aerodynamic rig design and test results. Overall, the design efforts and the data collected on test will form the foundation for continued development of additional technologies to enable successful RDECOM TR 18-D-76 designs for the stringent requirements of FVL applications.
