Aerodynamic Testing of a Circular Planform Concept Aircraft

Recktenwald, Bryan (2008-08-15)

Auburn University has entered into collaboration with Geobat Flying Saucer Aviation Inc. for aerodynamic and flow visualization studies of the Geobat aircraft. The aircraft model that was tested consisted of a circular ...

Collaborative UAS Control to Increase Deconfliction Ability in the NAS

Reitz, Brian (2009-07-15)

The progression of aviation has led to the strong desire to integrate unmanned aerial systems (UASs) into the national airspace system (NAS). In order for UASs to occupy the NAS concurrently with other aircraft, the ...

Development and Implementation of a Trajectory Prediction Methodology

Robertson, Clay Jackson (2012-04-16)

Operation of unmanned aircraft in the United States' National Airspace System (NAS) is currently severely restricted, primarily due to the need to ensure adequate separation between manned and unmanned aircraft (UA). A ...

An Experimental Investigation of Roll and Yaw Coupled Oscillations of a Delta Wing

Walker, John (2011-05-03)

An experimental investigation was undertaken to study roll and yaw coupled oscillation of a delta wing. Results indicated that the oscillations started at a mean α = 29 for all cases. Beyond which the amplitude of oscillations ...

A Feedback Linearization Approach for Panel Flutter Suppression with Piezolectric Actuation

Onawola, Oluseyi (2008-12-15)

A panel is subject to dynamic instability when induced aerodynamic loads under the supersonic/hypersonic environment result in a self-excited oscillation called panel flutter. The panel of an aircraft that flies at ...

Optimum Propeller Design for Electric UAVs

Wall, David (2012-05-16)

A propeller behaves as a rotating wing producing lift in the direction of the axis of rotation. Many previous propeller optimization methods have been developed, but usually focus on piston or turboprop applications. ...

Stability Analysis of a Segmented Free-wing Concept for UAS Gust Alleviation in Adverse Environments

Welstead, Jason (2009-08-03)

High altitude, long endurance (HALE) aircraft feature large wing spans and have very low wing loadings resulting in sensitivity to turbulence. While turbulence is usually quite low in the stratosphere where HALE aircraft ...

System Identification of General Aviation Aircraft Using the Filter Error Technique

Patel, Dakshesh (2007-12-15)

An overview of some past and modern applications of system identification techniques to aircraft is presented in this thesis, which traces progress and accomplishments in the field of system identification - especially ...

Yaw-Roll Coupled Oscillations of a Slender Delta Wing

Worley, John (2008-08-15)

The delta wing has been a highly studied aerial planform, from counter rotating vortices to a rolling `wing rock' motion. The research done at Auburn University is an extension of those studies. This research studies not ...
