Abstract

866,033. Propelling and manoeuvring ships. GILL PUMP & PROPULSION CO. Ltd. Dec. 22, 1959 [Dec. 22, 1958], No. 41376/58. Class 114. In a hydraulic jet propulsion apparatus comprising a pump 14 which draws water through an inlet passage at 16 from an opening in the hull 17 and delivers it through a discharge passage to a deflector nozzle 26 which deflects the water in a direction of flow having a substantial component at right angles to an approximately vertical axis 25 about which it is rotatable for steering and manoeuvring purposes, the deflector nozzle 26 comprises a hollow body containing an uninterrupted and undivided nozzle passage 27 having an inlet end of circular crosssection in planes normal to its axis of rotation 25 and an outlet end which, viewed along the line representing the mean direction of flow therefrom; is of approximately elliptical form, the contour of the surface of the nozzle passage from its inlet end over at least the greater part of its length being such that planes normal to the axis of rotation 25 intersect such surface along substantially circular arcs (complete circles 29 in upper portion and arcs 30 lower down) struck from centres which lie on a smooth curved line 32 extending from the axis of rotation towards the centre of the width of the nozzle outlet. Specifications 503,593, 658,822 and 662,973 are referred to in the Provisional Specification.
