Title:
ウォータージェット推進ボートにおける推進および流れ制御用機械的流体力学装置
Document Type and Number:
Japanese Patent JP2009543725
Kind Code:
A
Abstract:
The device includes conveying ducts of the fluid (2, 9), a tubular mean (1) with variable internal volume (1'), a tapered onion-shaped body (17) centred (18) inside the tubular mean, a nozzle (16) for the ejection of the fluid adjustable in position and opening for the variation of said internal volume (11), one or more gas injectors (21), and means to change the direction of the jet (6). In this way a fluid with variable characteristics can be obtained which allows the adjustment of the intensity, flow, direction and slant of the jet (6), moreover releasable also above the water surface (10), in view of the optimisation of the increased performances and consumption reduction. Unlike the devices of the known technique suitable only to convey the fluid and give the flow a single direction, the jet (6) is not diverted by other members, but is oriented through the joint (8) which allows its displacement in all the directions, in fact thanks to this said jet (6) can be directed without damping. It finds peculiar application in the propulsion and control of the hydrodynamic flow in the water-jet propelled boats or craft, besides as retrofit of easy embodiment to be installed also on the boats that have a traditional water-jet.
