EXPERIMENTAL PERFORMANCE OF A PARTIALLY SUBMERGED PROPELLER IN INCLINED FLOW
The potential benefit of using partially submerged propellers on certain special craft such as the surface-effect ships was presented in 1968. Since that time, the Naval Ship Research and Development Center has continued the investigation in order to establish as broad a data base as possible from which rational design studies may be performed. Among the various configurations, the latest to be investigated are inclined partially submerged propellers, the motivation being the possible gain in machinery arrangement, efficiency, and reduction in transverse forces. Experiments were performed with various combinations of shaft angle and blade rake angle up to 30 degrees while 30 percent and 50 percent submerged. The experiments confirmed that such benefits can indeed be obtained.
