Limited bridle-level asymmetry data were collected on three Orion main parachute cluster tests early in the development program. The results were published contemporaneously using analysis techniques developed by the Ares parachute program. Both programs seemed to indicate that large parachutes could develop line asymmetries far larger than what was assumed in design guides. Unfortunately, no additional asymmetry data were collected during Orion parachute development to corroborate these results. Recent high-fidelity data from Commercial Crew Program parachute system tests reinforce these legacy results. A method was developed to estimate suspension line-level asymmetry by “un-averaging” Orion bridle-level measurements using assumptions gleaned from the recent CCP experience. Efforts were made to improve the visualization of load asymmetry and its relationship with parachute geometric shape deformations.
