Designing A Control System to Adjust Surface Roughness of an Airfoil

This research focused on investigating flow control using surface roughness along the leading edge of an airfoil. The current design will entail a system that can accurately predict flow separation on the upper surface. This is done by measuring the angle of attack and static pressure to determine flow separation. For future research this can

Reducing Drag At High Angles of Attack with a Pimpled Airfoil

The objective of this project is to determine if altering a standard wing with tear-drop shaped pimples can reduce the effects of drag without utilizing expensive technology. To test this an airfoil based on a standard National Advisory Committee for Aeronautics 0012 model airfoil was designed with the tear-drop pimples and tested using a wind-tunnel,

Computational Fluid Dynamics Analysis of Leading Edge Roughness Devices

The objective for this research was to model the effects of a wing with leading-edge roughness device’s on coefficient of lift and drag when at high angles of attack near stall, the addition of which potentially increases the stall angle and reduces stall speed. This research was conducted using Computational Fluid Dynamics, modeling an airfoil
