Angle Of Attack Determination Using Inertial Navigation System Data From Flight Tests, Jack Kevin Ly

Masters Theses

Engineers and pilots rely on mechanical flow angle vanes on air data probes to determine the angle of attack of the aircraft in flight. These probes, however, are costly, come with inherent measurement errors, affect the flight characteristics of the aircraft, and are potentially dangerous in envelope expansion flights. Advances in the accuracy, usability, and affordability of inertial navigation systems allow for angle of attack to be determined accurately without direct measurement of the airflow around the aircraft. Utilizing an algorithm developed from aircraft equations of motion, a post-flight data review is completed as the first step in proving the …

Flight Testing The Piper Pa-32 Saratoga And Pa-31 Navajo, Matthew John Dimaiolo

Masters Theses

The purpose of this thesis was to flight test the University of Tennessee Space Institute’s PA-32 Saratoga and PA-31 Navajo and provide baseline data for future students to reference. Flight tests consisted of both performance and stability and control parameters using a variety of flight test techniques. The tests selected represent the fundamentals that are taught in classes and short courses at the university, beginning with the air data system calibration, proceeding to cruise and climb performance, to stall performance and characteristics, and to static and dynamic stability.

After an introduction and description of the aircraft and flight test program, …
