Abstract : An important consideration necessary to the successful development of a Deep Submergence Rescue Vehicle (DSRV) is the establishment of the vehicle controllability requirements in the critical hatch-mating operation. This report describes a mathematical model of the vehicle/control/display system used in piloted simulation studies of these requirements. The complete six degree-of-freedom equations are discussed and the simplifications which were made for mechanization on an analog computer are described. Preliminary results aimed at validating the model and at defining fundamental augmentation requirements for adequate control of the vehicle are discussed. It is shown that hatch-mating can be performed with a stability-augmented vehicle within a reasonable period of time under a broad range of conditions. It is concluded that the simulation is sufficiently representative to permit the investigation of many complex problems associated with DSRV controllability. (Author)
