This memorandum presents a method of predicting selected performance characteristics of aerodynamic deceleration devices. Basic trajectory equations were developed and then expanded through the application of accepted principles which influence the performance of deceleration devices. Incompressible flow and compressible flow were considered. A particular set of equations were developed to model ribless guide surface parachute performance in the troposphere at speeds less than Mach 1. A comparison of samples of actual and predicted test data is also presented to illustrate the relative accuracy of this method of prediction.
