| These results emphasize the importance of examining a range of locomotor behaviors when defining the hydrodynamic repertoire of aquatic animal propulsors. |
| Locomotor forces experienced by aquatic propulsors can be calculated as the reaction to the time rate of change in wake momentum. |
| The propulsors kicked in and the craft was suddenly floating on a large pocket of air. |
| For swimming animals, there has been extensive study of the anatomy and kinematics of aquatic propulsors, as well as description of their neuromuscular control. |
| Second, the model can be used for many fast swimmers, although lifting-wing models were developed for the fastest swimming fish with high aspect ratio oscillatory propulsors. |
| Submarine engineers eager to copy these features are now experimenting with new kinds of flexible propellers, called propulsors, which resemble the dolphin's tail. |
