Overview of the Applied Aerodynamics Division [PDF]

A major reorganization of the Aeronautics Directorate of the Langley Research Center occurred in early 1989. As a result of this reorganization, the scope of research in the Applied Aeronautics Division is now quite different than that in the past.

Design and Aerodynamic Performance Study of a Butterfly‐Inspired Vertical Axis Wind Turbine for Urban and Aviation Zone Wind Energy Applications

Modelling and Simulation in Engineering, Volume 2025, Issue 1, 2025.
This study presents the development of a butterfly‐inspired vertical axis wind turbine (BAWT), integrating drag‐ and lift‐based mechanisms inspired by biological structures. By combining Savonius rotors, known for their self‐starting capability and torque stability at low wind speeds, with airfoil blades that enhance performance at higher tip‐speed ...

Turbine vane coolant flow variations and calculated effects on metal temperatures [PDF]

Seventy-two air-cooled turbine vanes were tested to determine coolant flow variations among the vanes. Calculations were made to estimate the effect of measured coolant flow variations on local vane metal temperatures.
