Unique stealth unmanned aerial vehicle (UAV) Houck aircraft design program.

This report covers the collaborative activities conducted under the leadership of the University of Dayton Research Institute on the Unique Stealth Unmanned Aerial Vehicle (UAV) Houck Aircraft Design Program. This was organized in five phases: aerodynamic evaluation of 6-inch model; aerodynamic evaluation of 24-inch model; design exploration for the Preferred System Concept; design of Preferred System Concept; and fabrication of flying prototype aircraft. Overall, this configuration, as modeled, was found not to have aerodynamic characteristics markedly better than existing small unmanned aircraft. It may have potential to show benefit over existing aircraft in other areas though, including structural weight required as a result of the joined tips, size required to package the aircraft for man-portability due to its limited span, and range of c.g. travel owing to large longitudinal wing spacing for trim. To understand potential benefits in these areas, these characteristics would need to be assessed in further studies using different, higher fidelity methods.Photocopy."Final Report: January 1, 2006 -- May 1, 2008.""November 2008."Includes bibliographic references (page 91).This report covers the collaborative activities conducted under the leadership of the University of Dayton Research Institute on the Unique Stealth Unmanned Aerial Vehicle (UAV) Houck Aircraft Design Program.
