Coupling plasma plume of a low-power magnetically shielded Hall thruster with a hollow cathode
Chinese Journal of Aeronautics, 2020 The coupling region of a Hall thruster with a hollow cathode is the region between the cathode and the thruster plume. The characteristics of plasma in that region are complicated and strongly associated with the thruster working conditions and the ...

This paper presents the thruster modeling for a Hovering Autonomous Underwater Vehicle developed by Underwater, Control, and Robotics Group. Bollard-pull experiments are done to find the relationship between axial forces generated by thrusters and input signal given to Arduino Uno board in degree, taking into account the effect of thruster-thruster and

Numerical Prediction of Thruster-Thruster Interaction
Volume 4: Ocean Engineering; Ocean Renewable Energy; Ocean Space Utilization, Parts A and B, 2009Many vessels deploying offshore activities nowadays are dynamically positioned by multiple azimuth thrusters instead of anchors. The multiple propulsor set up, gives a considerable flexibility to work fast and accurate. Due to the fact that the thrusters are positioned relative close to one another their performance is influenced.
