- Аннотация: The efficiency of two types of wave propulsors (WPs) (a swinging spring-loaded wing WPand a direct-flow WP) is experimentally studied on a model of a small-waterplane-area-twin-hull(SWATH) boat. The NACA0015 airfoil was used as an operating element of both the swinging andthe direct-flow WPs. In the case of a direct-flow WP, the flat airfoil was rigidly fixed relative to theboat hull with an chord inclination of 30. The operating efficiency of the wave propulsors is studiedfor waves of various lengths depending on the draft of the SWATH boat hulls, and in the case of aswinging spring-loaded wing WP, also on the submergence depth of the propulsor. Using the results oftowing tests, the thrust force of a direct-flow WP is estimated under various operating conditions. It isfound that with increase in the submergence depth of the boat hulls, the efficiency of the direct-flowWP increases, while the efficiency of the swinging WP decreases, however, it largely retains itsoperability, provided that the WP operating element remains at the optimal depth close to the watersurface.
