Engineers are often required to design decelerator systems which are deployed in crosswind orientations. If the system is not designed to minimize “line sail”, damage to the parachutes could result. A Reentry Vehicle Analysis Code (RVAC) and an accompanying graphics animation software program (DISPLAY) are presented in this paper. These computer codes allow the user to quickly apply the Purvis line sail modeling technique to any vehicle and then observe the relative motion of the vehicle, nose cap, suspension lines, pilot and drogue bags and canopies on a computer screen. Data files are created which allow plots of velocities, spacial positions, and dynamic pressures versus time to be generated. The code is an important tool for the design engineer because it integrates 2 degree of freedom (DOF) line sail equations with a 3 DOF model of the reentry body and jettisoned nose cap to provide an animated output.
