拡張フローノズル
Document Type and Number:
Japanese Patent JP7009656
Kind Code:
B2
Abstract:
Disclosed are an improved nozzle for an unmanned underwater vehicle (UUV), and a method for operating the same. The nozzle includes a first rigid member operatively coupled to a UUV steering mechanism. The nozzle also has a second rigid member, coupled to the first rigid member by a flexible bellows according to a configurable operating angle. The nozzle does not extend beyond a bounding surface when stored but does when deployed. Water traversing the first rigid member and contacting the second rigid member produces a reactive force according to the configurable operating angle. Simultaneous and independent control of the volume of fluid traversing several such nozzles in the UUV, and their respective orientations and operating angles, permits automatic station-keeping or navigation according to another guidance objective.
