These projects are part of a research effort by the T*AFSM in collaboration with US Army the Natick Soldier Center. Soft-landing of cargo parachutes is achieved by contracting pneumatic muscles between the parachute risers and payload. The payload motion and canopy deformation for a soft-landing G-12 is simulated in the FSI computations.

Figure 1: Payload path during the soft-landing of G-12 and pressure distribution on the canopy.

When one parachute comes close to the top of another, the upper parachute loses its drag and might collapse. The motion and deformation of the upper parachute is studied in the FSI simulation.
