Abstract: In one embodiment, a centrifugal impeller is described having a front side with airfoils and a back side. A conduit may be formed between the front side and the back side, or any other side, and may convey pressurized working fluid between the two. The conduit may pass relatively high pressure working fluid between any two locations such as from the front side to the back side. The conduit may include an aperture located on the front side and an aperture located on the back side. Any number of conduits may be defined within the centrifugal impeller. Apertures located on the front side of the impeller may be formed in any suitable place, such as a hub of the impeller or an airfoil surface, to set forth just two non-limiting examples.

Abstract: A nozzle device defines a passageway including an outlet to discharge working fluid to produce thrust. This device includes a vectoring mechanism having three or more vanes pivotally mounted across the passageway and a linkage pivotally coupling the vanes together. This linkage includes a first arm fixed to a first one of the vanes to pivot therewith about a first pivot axis, a second arm and a third arm fixed to a second one of the vanes to pivot therewith about a second pivot axis, and a fourth arm fixed to a third one of the vanes to pivot therewith about a third pivot axis. A first connecting link pivotally couples the first arm and the second arm together, and a second connecting link pivotally couples the third arm and the fourth arm together. The relative angular positioning of the arms with respect to the corresponding pivot axes and/or the arm links can be varied to define different vectoring schedules with the mechanism linkage.
