Soft Landing of a G-12 Cargo Parachute with Multistage PMA Retractions

Project Supervisors:
Sunil Sathe, T*AFSM

Principal Investigator:
Professor Tayfun E. Tezduyar, T*AFSM

This project is part of a research effort by the T*AFSM in collaboration with US Army Natick Soldier Center. The objective in this project is to study the effect of multistage Pneumatic Muscle Actuator (PMA) retractions on soft landing a G-12 cargo parachute. We investigated how a sequence of retracting and holding the PMA's affected both the drag and descent speed of the parachute.
