JET PROPULSION SYSTEM PARTICULARLY FOR A WATERCRAFT, AND METHOD FOR RETROFITTING A JET PROPULSION SYSTEM

摘要

The invention relates to a jet propulsion system particularly for a watercraft, comprising at least one propulsion unit that has - a rotor the inner circumference of which has rotor blades secured thereto, and - a housing in which said rotor is rotatably mounted by means of at least one bearing assembly; - said bearing assembly comprising at least one axial bearing and at least one radial bearing. The claimed jet propulsion system is characterised in that the rotor is connected to the housing such that electricity can be conducted.
