Galatea fin propulsion
Galatea is a collaborative research project between Delft University of Technology and Wageningen
University. The project focuses on undulatory fin propulsion, a technique found in nature used by species that excel in manoeuvrability. For example seahorses, cuttlefish, rays and knife fish all have a similar propulsion system. Research into an integral propulsive solution that comprises an undulatory fin as its main propeller can result in a highly manoeuvrable underwater vehicle, which has a minimal impact on the environment.

The objectives of the Galatea project are to develop, design, build and test a bio-inspired Autonomous Underwater Vehicle (AUV). Initially, the AUV will operate as a research platform to investigate the unique features of undulatory fin propulsion. A fully operational model with undulating fin propulsion was tested by two PhD students from both universities. The tests with the model in waves were invaluable, because the orbital wave motions act as a disturbance, which makes the manoeuvrability more difficult and realistic.
