NASA Ringsail Parachute (Detail)



Detailed fluid dynamics computation of a ringsail parachute for the Orion project.

The ringsail parachute is a very complex geometry because it has several gaps and holes that contribute to geometric porosity. The geometric porosity affects aerodynamic performance including vertical descent speed and gliding characteristics of the parachute. This computation includes all gaps and holes to model the geometric porosity. (T*AFSM)
