A numerical deployment simulation with the capability to predict line sail is presented. A finite element approach is used in which both canopy and suspension lines are modeled as flexible, distributed-mass structures connected to a finite-mass forebody. Translation and rotation of both the forebody and the deployment bag are determined from three-degree-of-freedom flight mechanics equations. The model includes all aspects of the deployment problem, such as suspension line aerodynamics, line ties, and canopy/deployment bag friction. The model has been verified by comparison with experimental data and used to investigate proposed solutions for a system with a line sail problem. (ERA citation 09:017066)
