Abstract
The swimming motion of a fish-like body with two undulating side fins similar to a ray and a squid is investigated through model experiments and flow computation around the body. Two models were constructed and experiments were conducted. One model consists of a big strut and two drive units for port and starboard sides above the water surface. The drive unit part is composed of one motor and 15 scotch yokes that drive the 15 bones of the side fin through the vertical push rods in the strut. By using it, the free-run tests with floating bodies and hydrodynamic force measurements were carried out. The other model has 16 servomotor units for both sides of the model. Each servomotor is controlled separately by a remote computer to make any kind of motion of the fin. Some preliminary tests were conducted for the latter model.
