The Solo AFF jump, however, is for those ready to go all in! A general theory on mathematical modeling of elastic parachute suspension lines during the unfurling process was developed. You want the suspension lines holding until the point of parachute material failure. 18 indicates that a suspension-line shock was generated around each suspension line, disrupting the canopy bow-shock, and increasing the flow field instability around the rigid parachute system [25, 77, 81, 86, 87]. This distortion of the center section results in a significant alteration of the glide ratio of the parachute by simultaneously reducing the forward speed and increasing the rate of descent. This report develops a generic opening shock analysis that permits calculation of velocity profiles, shock factors, maximum shock forces and their time of occurrence during deployment for many types of parachutes.
