An apparatus for controlling airflow in a duct of an aircraft galley chiller includes first and second legs having ends connected together to form a vane, and free ends configured to be attached within the duct. A free end of one first leg may have a beveled edge, and the free end of the other leg may have a flat edge, and each leg may have one or more score lines to aid cutting lengths of the first and second legs. The legs are connected together at a predetermined fixed angle, or at an adjustable angle, such as by an adjustable hinge. A pair of opposing vanes may be attached within opposing sides of the duct to form a venturi within the duct.

1. An apparatus for controlling airflow in a duct of an aircraft galley chiller, comprising: a first leg having opposing first and second ends; anda second leg having opposing first and second ends, said first and second legs being connected together at said second ends of said first and second legs
1. An apparatus for controlling airflow in a duct of an aircraft galley chiller, comprising: a first leg having opposing first and second ends; anda second leg having opposing first and second ends, said first and second legs being connected together at said second ends of said first and second legs to form a vane having a protruding joint at said second ends of said first and second legs, and at least one of said first ends of said first and second legs being configured to be attached within the duct,wherein said first end of said first leg has a beveled edge, and said first end of said second leg has a flat edge, and wherein said first leg and said second leg each have at least one score line to aid cutting of the first and second legs for reduction of lengths of the first and second legs. 2. The apparatus of claim 1, wherein said at least one score line of said first leg forms an oblique angle with the first leg such that cutting of said first leg along said at least one score line of said first leg will produce a beveled edge at said first end of said first leg, and said at least one score line of said second leg forms a right angle with said second leg such that cutting of said second leg along said at least one score line of said second leg will produce a flat edge at said first end of said second leg. 3. The apparatus of claim 1, wherein said first and second legs are formed of a rigid material. 4. The apparatus of claim 1, wherein said first and second legs are formed of a solid continuous material. 5. The apparatus of claim 1, wherein said first and second legs are formed of a stiff malleable material. 6. The apparatus of claim 1, wherein said first and second legs are formed of a material that becomes malleable when heated, but is inflexible when cooled to room temperature. 7. The apparatus of claim 1, wherein said first and second legs are connected together at a predetermined fixed angle. 8. The apparatus of claim 1, wherein said first and second legs are connected together at an adjustable angle. 9. The apparatus of claim 1, wherein the at least one score line of said first leg is aligned with the at least one score line of said second leg. 10. An apparatus for controlling airflow in a duct of an aircraft galley chiller, comprising: a duct of an aircraft galley chiller; andat least one vane attached within the duct, said at least one vane including:a first leg having opposing first and second ends; anda second leg having opposing first and second ends, said first and second legs being connected together at said second ends of said first and second legs to form a vane having a protruding joint at said second ends of said first and second legs, and at least one of said first ends of said first and second legs being attached within said duct,wherein said first end of said first leg has a beveled edge, and said first end of said second leg has a flat edge, and wherein said first leg and said second leg each have at least one score line to aid cutting of the first and second legs for reduction of lengths of the first and second legs. 11. The apparatus of claim 10, wherein said at least one vane comprises first and second vanes attached within opposing sides of the duct, said first and second vanes forming a venturi within said duct. 12. The apparatus of claim 10, wherein said at least one score line of said first leg forms an oblique angle with the first leg such that cutting of said first leg along said at least one score line of said first leg will produce a beveled edge at said first end of said first leg, and said at least one score line of said second leg forms a right angle with said second leg such that cutting of said second leg along said at least one score line of said second leg will produce a flat edge at said first end of said second leg. 13. The apparatus of claim 10, wherein said first and second legs are formed of a rigid material. 14. The apparatus of claim 10, wherein said first and second legs are formed of a solid continuous material. 15. The apparatus of claim 10, wherein said first and second legs are formed of a stiff malleable material. 16. The apparatus of claim 10, wherein said first and second legs are connected together at a predetermined fixed angle. 17. The apparatus of claim 10, wherein said first and second legs are connected together at an adjustable angle by an adjustable hinge. 18. The apparatus of claim 10, wherein said first leg and said second leg are composed of a non-metal material. 19. The apparatus of claim 10, wherein the at least one score line of said first leg is aligned with the at least one score line of said second leg.
