This project is part of a research effort by the T*AFSM in collaboration with US Army Natick Center. When one parachute comes close to the top of another, the upper parachute loses its drag and might collapse. The objective in this project is to study the aerodynamic behavior of the upper parachute in terms of drag and lift, and to explore the possibility of maneuvering the upper parachute by pulling the risers.
