Aeroelastic Characteri stics of Rotor Blades with Trailing Edge Flaps
International Journal of Aeronautical and Space Sciences, 2007 The aeroelastic analysis of rotor blades with trailing edge flaps, focused on reducing vibration while minimizing control effort, are investigated using large deflection-type beam theory in forward flight. The rotor blade aerodynamic forces are calculated using two-dimensional quasi-steady strip theory. For the analysis of forward flight, the nonlinear

Trailing Edge Loss of Choked Organic Vapor Turbine Blades
International Journal of Turbomachinery, Propulsion and PowerThe present study reports the outcome of an experimental study of organic vapor trailing edge flows. As a working fluid, the organic vapor Novec 649 was used under representative pressure and temperature conditions for organic Rankine cycle (ORC) turbine applications characterized by values of the fundamental derivative of gas dynamics below unity.
