The Team for Advanced Flow Simulation and Modeling (T☆AFSM) at Rice University has been developing the Stabilized Space--Time Fluid--Structure Interaction core technologies in conjunction with an array of special techniques to overcome the complexities present in modeling ringsail parachutes. Flight characteristics of single and clustered ringsail parachutes are explained. Ringsail modeling techniques are employed to examine and discern the parachute's aerodynamic characteristics. Several design modifications, including suspension line length ratio, over-inflation control line and canopy loading are investigated. The application of the ringsail modeling techniques to two and three parachutes in a cluster is demonstrated.
