RPT - Aerodynamic Decelerator Systems Laboratory
RPT Home
The goal of this project was to develop a fleet of unmanned aerial systems (UAS) carrying a variety of sensors enabling persistent surveillance of different test activities from the air. Four different-size UAS were considered as a remotely piloted testbed (RPT) to support the aforementioned mission. Figure A shows these platforms and Table A provides their basic characteristics.

The development of RPT included UAS modeling and integration with a Piccolo II autopilot. For each platform the modeling process started from describing aircraft geometry (Fig.B) and evaluating its inertial properties (Fig.C).
