DESIGN OF TEST RIG FOR HYDRODYNAMICALLY COUPLED CONTRAROTATING PROPELLER PROPULSION SYSTEM

There appears to be universal agreement with respect to the improvements to be gained from the action of contrarotating propellers (CR). From a machinery design point of view, various CR arrangements are feasible. This report discusses design of a model CR test rig using an epicyclic gear as the CR shaft output generator and a speed reducer. The report further discusses the options available to the propulsion systems designers and the implication of the various options on such parameters as mechanical efficiency, size, arrangement, etc. The introduction of the simple epicyclic gear as the CR shaft generator introduces the concept of hydrodynamically coupled CR propellers.
