Application of a panel method to wake-vortex/wing interaction and comparison with experimental data
Author(s): Smith, Brian E.; Ross, James C.
Abstract: The ability of the Vortex Separation AEROdynamics (VSAERO) program to calculate aerodynamic loads on wings due to interaction with free vortices was studied. The loads were calculated for various positions of a downstream ...

Theoretical and experimental study of flow-control devices for inlets of indraft wind tunnels
Author(s): Ross, James C.
Abstract: The design of closed circuit wind tunnels has historically been performed using rule of thumb which have evolved over the years into a body of useful guidelines. The development of indraft wind tunnels, however, has not been ...

Lift-Enhancing Tabs on Multielement Airfoils
Author(s): Ross, James C.; Storms, Bruce L.; Carrannanto, Paul G.
Abstract: The use of flat-plate tabs (similar to Gurney flaps) to enhance the lift of multielement airfoils is extended here by placing them on the pressure side and near the trailing edge of the main element rather than just on the ...
