Propulsion system |
| abstract |
A propulsion system ( 163 ) having various applications one of which is as a marine drive system for watercraft. The propulsion system ( 163 ) comprises a flow passage ( 173 ) having an intake ( 175 ) for communicating with a source of working fluid such as seawater and an outlet ( 177 ). A mixing zone ( 209 ) is disposed within the flow passage ( 173 ) between the intake ( 175 ) and the outlet ( 177 ). An injection means including annular nozzle ( 217 ) is provided for injecting a hot compressible driving fluid ( 175 ) such as steam into the mixing zone ( 209 ) in a flow direction towards the outlet ( 177 ). The arrangement is such that the interaction between the steam and the seawater in the mixing zone ( 207 ) develops a pressure reduction in the mixing zone ( 207 ) to cause seawater to be drawn from the source into the mixing zone ( 207 ) and propelled towards the outlet ( 177 ). A marine drive unit incorporating the propulsion system is also described and claimed, as well as other aspects related to the propulsion system. |
