Unsteady Aerodynamics

My research group and I are currently working on a funded research project dealing with the role of unsteady aerodynamics in the motion of unstable bodies. The primary mode of instability is static margin, causing high angular rates. These high angular rates are not accurately predicted by static aerodynamic analysis. The goal of the study is to provide better body motion prediction taking into account unsteady aerodynamic effects.

We conduct a majority of our experimental data at a free-flight test facility located in Reedsville, WV. At this location, we have a large outdoor range as well as a large 16' x 16' x 120' wind tunnel. Either location can be outfitted with up to 70 VICON motion capture cameras, as well as multiple high-speed cameras to capture vehicle position and orientation.

Thermal and Fluid Flow Analysis

WVU is a partner with Boston Engineering Corporation working to improve the efficiency of diver body temperature regulation systems. Our team is conducting both experimental analysis as well as computational fluid dynamics to document and predict heat loss and pressure drop through a variety of system components.


Unmanned Aerial Systems

Our group, teaming with NextGen Federal Systems, was awarded an Army SBIR to develop a small and efficient unmanned aerial system. The UAS will be used to autonomously conduct ISR missions while adhering to challenges such as form factor, range and endurance, and sensor payload requirements. We are primarily tasked with platform design and development along with aerodynamic testing and validation. We utilize our environmental wind tunnel, thrust stands, and tradition force and moment balances to capture aerodynamic performance.
