Final Report for M-12-08: Rotorcraft Autorotation Study

Report No. ARL-TR-6804

Abstract: A system for automated execution of the DESCENT rotorcraft autorotation model was developed, and a sensitivity study of various input parameters was completed for an analysis involving a generic air vehicle. Separately, the structural dynamics of an impacting helicopter were modeled in the MADYMO structural dynamics model to better inform the optimization priorities of DESCENT. The structural modeling explored loading transmitted to hypothetical occupants as well as vehicle loading.
