Abstract: An enclosure assembly for enclosing a portion of a fuel delivery system of an engine, such as a portion of a fuel nozzle body that extends away from the engine, is disclosed herein. The enclosure assembly includes a nozzle body cover portion operable to enclose a fuel nozzle body. The enclosure assembly also includes a fuel line cover portion unitary with the nozzle body cover portion and operable to enclose a portion of a fuel supply line connected to the fuel nozzle body. Both the nozzle body cover portion and the fuel line cover portion are defined by a first and second half-shells operable to cooperate together in a clam shell arrangement.

Abstract: A composite component includes an inner core formed from a first composite material having discontinuous fibers. An outer sleeve is formed from a second composite material different from the first, and having continuous fibers. The outer sleeve generally surrounds and is bonded or otherwise connected to the inner core. The component is made by injecting or otherwise introducing thermoplastic fiber composite material including chopped or otherwise discontinuous fibers into a mold to form the inner core having a first portion with smooth surfaces and integrally joined to a second portion with bumps and ridges. The injected thermoplastic fiber composite material is cured and then removed from the mold. A layup including one or more surface plies of a thermoset continuous fiber composite material is then applied to the smooth first portion of the core. The surface plies then are compressed and cured in a mold.

Abstract: An airfoil or vane for a combustive power plant includes an inner core formed from a first composite material having discontinuous fibers. An outer sleeve is formed from a second composite material having continuous fibers. The first composite material is different from the second composite material. The outer sleeve generally surrounds and is bonded or otherwise connected to the inner core. A method of fabrication includes injecting or otherwise introducing thermoplastic fiber composite material including chopped or otherwise discontinuous fibers into a mold to form the core and platforms of an airfoil assembly. The injected thermoplastic fiber composite material is then cured in the mold. The cured thermoplastic fiber composite material is then removed from the mold. A layup including one or more surface plies of a thermoset continuous fiber composite material is then applied to the core material. The surface plies are then compressed and cured in a mold.

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.
