Simulation of a G-11 Parachute Soft-Landing with Delayed Muscle Retraction
Grant Gillary, US Naval Academy
This project is a part of a research effort by the T*AFSM in
collaboration with US Army Natick Soldier Center.
Pneumatic Muscle Actuators (PMAs) can be used for soft landing of cargo
parachutes. In this fluid-structure interaction (FSI) simulation we investigate
how different ways of using these PMAs can influence the descent speed and
other performance characteristics of cargo parachutes.
