Abstract: There is provided a water jet propulsion device 10 for a water vehicle, comprising a main duct 12 having a main inlet 14 that is arranged to be submerged in use and a main outlet 16; a pump disposed between the main inlet 14 and the main outlet 16; and a plurality of injection nozzles 40, 50, 60, 70 each arranged to selectively eject a jet of fluid into a different region A, B, C, D susceptible to cavitation, so as to re-energise the fluid flow in that region.

Abstract: A water jet propulsion device 10 for a water vehicle, such as a boat, is disclosed. The propulsion device 10 comprises a main duct 12 having a main inlet 14 that is arranged to be submerged in use and a main outlet 16, an impeller 30 disposed within the main duct 12 between the main inlet 14 and the main outlet 16, and at least one auxiliary duct 24 having an auxiliary inlet 26 that is arranged to be submerged in use and an auxiliary outlet 28 that opens into the main duct 12 upstream of the impeller 30.

Abstract: An interface module for a power distribution and control system for a vehicle is described. The interface module includes at least one first link configured to receive an input from input devices on the vehicle, at least one second link configured to control output devices on the vehicle, at least one third link configured to communicate with a communication network. The module further includes control logic configured to store a record of output devices associated with the interface module and to process a configuration file to determine whether any of the output devices have been designated as controlling a mission critical function.
