The thruster contained a large-diameter, slowly rotating blade with nozzles that diffused the propulsive flow, minimizing the churning that would otherwise disturb the caked silt.
The stiffening effects of the rotating blade are discussed, using the multi-body dynamics method. The influence of the dynamic stiffening effect on the blade vibration mode is then analyzed.
