Single-Winged Autorotating Brake for Sensor Deployment on Mars

Abstract

The following pages describe the development of a nonlinear simulation, results for the Martian entry problem, and a sizing study to determine whether the approach is feasible. The nonlinear simulation is described here and results are presented for several cases using Martian and Terrestrial atmosphere models. The results show that a 2.5 kg payload could be successfully delivered to the Martian surface using this approach and the report suggests an earth-based test of the system. Prior to the specific analysis presented here, a theoretical study of the mechanics of autorotation was completed, and a summary of this work is also included as part of this final report.
