Abstract

1314976 Water jet propulsion HYDROCUSHION CONSULTANTS Ltd and C VIN. TEN 25 Aug 1970 [26 Aug 1969] 42395/69 Heading B7V A water jet propulsion unit comprises a mixed flow impeller 4 rotatable in a circular duct 1, the cross-section of which decreases smoothly from inlet to outlet. The unit is also provided with a rudder 20 and a pair of wide bottom doors (24) 25 which can be closed over the outlet to reverse the thrust. The water inlet (not shown) is flush with the bottom of the boat.
