The ejector recirculation lift system was investigated as means of improving the internal-flow and performance characteristics of air cushion vehicles. The concept permits larger unobstructed stowage areas and lower structural weight. In addition, the system minimizes the performance degradation of air cushion vehicles associated with higher speed and increased base pressure. The study involved two phases ejector optimization and fabrication of an air source having the mass flow and pressure characteristics necessary for a vehicle of moderate size. The results indicate that an energy recovery system of this type is feasible and that performance may be predicted with the same degree of accuracy as for conventional axial flow fanductnozzle systems.
