Abstract:

High performance of fast swimming sea animals challenges naval designers to provide undulating flexible hulls instead of conventional rigid ships driven by propellers. Natures method of self-locomotion assures silence as well as economy provided the barrier of complete flexibility is surmounted by modern technology in a practical manner. Natures challenge, as shown by the swimming vehicle, is a structural approach to noise reduction by eliminating the propeller. Experiments with the swimming vehicle show an improvement in boundary-layer conditions, as found in nature, by wiping away the turbulent body wake. Tests of the swimming catamaran were documented with respect to speed and other parameters, but the slow speeds attained due to low power are not significant nor inherent in the swimming method.
