Definitions
- Figure 1 is an illustration of a marine ducted propeller jet propulsion apparatus according to an exemplary embodiment of the present disclosure
- Figure 4 is an exploded view of a marine ducted propeller jet propulsion apparatus according to an exemplary embodiment of Figure 1 ;
- Figure 5 is an illustration of an impeller and a diffuser for a marine ducted propeller jet propulsion apparatus according to an exemplary embodiment of Figure 1;
- Figure 7 is various views of an impeller for a marine ducted propeller jet propulsion apparatus according to an exemplary embodiment of the present disclosure
- An interchangeable thrust bearing assembly 30 also provides for the thrust bearing to be changed in position whether the vessel 12 is in the water or not by disconnecting a drive coupling positioned at the end of a drive shaft and removing the securing bolts, which then allows the interchanging of the shaft thrust bearing assembly 30.
- the thrust bearing assembly 30 is designed to be self-greasing to ensure that the bearings and seals are always lubricated.
- the vanes 208 also act to dampen any preliminary pre-rotation or turbulence in the inlet water column to the impeller 202. It is important that the internal flow characteristic of the intake 203 accommodates the volumetric intrusion of the straightener and directional vanes 206, 208 by cross-section adjustment to the shape of the intake transition from the intake 203 to the impeller face to ensure that the flow through the intake to the impeller 202 is volumetrically uninhibited or restricted. Not doing so can create a flow restriction which can induce a pressure change in the flow to the impeller 202 which can induce pressure changes and aeration in the flow and cavitation.
- an arm-hole duct 216 is provided to enable quick access to passage 212.
- Duct 216 is situated at bend 120 and comprises a cylindrical housing 220, with an outer flange 222 and a plug 224.
- Plug 224 is provided with a solid section 226 affixed to a flanged cover 228 which completely fills the duct housing 220.
- Section 226 is provided with a smooth contoured surface that matches the surface section removed from the upper intake housing 104 in bend 120 when duct 216 is installed.
- Duct 216 when properly plugged in position, poses no flow disruption.
- a bypass valve assembly (not shown) can also be fitted in housing 104 near inlet 203 shown in FIGS. 1 and 2. Excess water is bled through bypass valve assembly (not shown) if water pressure between the hull of the vessel 12 and the induction inlet 106 exceeds handling capacity exceeds 3 to 6 psi. Excess water buildup, known colloquially as balling, is a common occurrence in marine jet propulsion units. Occurring at high vessel speeds when the vessel is undergoing sharp maneuvers and/or during rough sea conditions, excessive balling introduces a drag characteristic upon the hull of vessel 12 and affects the propulsive efficiency of unit 10.
- the valve assembly (not shown) functions as an anti-balling device to relieve pressure.
- the intake pressure release by-pass valve 232 can work in conjunction with the induction plate by allowing for excessive pressure build up in front of the impeller 202 to be released around the impeller into the exhaust heat exchanger 207.
- the pressure by-pass valve pressure release valve (not shown) can be set to the desired pressure release as may be needed subject to sea conditions or the work load of the vessel to improve unit performance. This is controlled automatically by pressure sensors attached to the side of the housing 104 that relay the running pressure before the impeller 202 so the valve can be adjusted by a programmable controller (not shown).
- the thickness 284 of blade 250 is low profile foiled in design as a result of improved design instead of substantially uniform as in previous defined.
- Leading edge has substantially uniform tapering with a maximum thickness at a midpoint approximately equidistant from either edge.
- the leading edge entry angle needs to be between 13 and 15 degrees related to the rotary velocity of the impeller 202.
- the pitch effect of the impeller blade(s) 250 on the accelerated flow can be enhanced by the extension of the blade width beyond the required pitch length by adding a continued parallel section to end of the assembly impeller hub 252 and to the width of the blades representing a continuation of the exiting pitch of the blade 250.
- the designed pitch of the impeller blade 250 can be a combined interpretation of the required efflux velocity efficiency and the power available from the power source driving the impeller 202. This power source can be from any type of drive, whether it is electric, gasoline, diesel, gas or alternative fuel driven.
- the interchangeable diffuser/confusor blade component 245 can allow for the changing of the leading edge blades to the diffuser 242 to be replaced if damaged, or to change the pitch of the leading edge of the diffuser vanes 244a if they need to be adjusted to meet the needs of the trailing edge velocities of the impeller 202 or a change in pitch of the impeller blades 250.
- the radii of the leading edge of the diffuser blades 244 to their straight trailing section can be of a greater radius than in previous designs to ensure a less turbulent transition of the flow from the impeller blade 250, which can allow the change from rotary flow to linear/laminar type flow to be less aggressive reducing turbulent flow.
- the diffuser/confusor hub 243 preferably has an inwardly tapered convex surface and annular interior, oppositely disposed in relation to hub impeller 252.
- Hub 243 comprises a large flat diameter leading end, decreasing variable diameter mid-section and a small diameter trailing end forming a rounded nose with a concentric bore cavity 246 drilled through the middle thereof and a central annular end extension.
- Concentric outer annular cavity 246 is primarily for reduction of excess weight providing hub 252b with walls of substantially constant thickness.
- a concentric inner annular bore 246 defines a cylindrical housing for a support bearing for impeller shaft 204 supporting impeller 202. .
- Bore 246 has a reduced diameter in the nose section of hub 243 as required by design strength criteria.
- Impeller shaft 204 extending axially through propulsion system 10 is provided with a first bearing support by interchangeable bearing assembly 30 mounted on inlet housing 203 and a second bearing support 247 at fixed hub 243.
- Bearing assembly 30 includes housing, roller bearing and locking ring.
- Bearing assembly 30 may also include a gear housing (not shown) for unit gearing to a particular prime mover requirement.
