Vibration-damping blankets are attached to the back surfaces of fairing panels of a flight vehicle (e.g., an aircraft or spacecraft) to reduce vibration, fatigue, structure and airborne transmitted energy, and cabin noise. In one case, the flight vehicle fairing has an exterior comprising exterior surfaces of a multiplicity of removable panels. A method of retrofitting the flight vehicle with vibration-damping blankets comprises: removing a panel from the flight vehicle exterior; attaching a vibration-damping blanket to a back surface of the removed panel; and installing the panel with attached vibration-damping blanket on the flight vehicle with the exterior surface of the panel forming part of the flight vehicle exterior. In one embodiment, the vibration-damping blanket comprises polymeric (e.g., aromatic polyamide) fibers in a nonwoven structure.

1. A method for retrofitting a flight vehicle fairing that has a removable panel, which removable panel has a front wall that forms part of an exterior surface of the flight vehicle, a rear wall that is not part of the exterior surface of the flight vehicle, and a honeycomb structure at least partially filled with foam and/or particles and disposed between the front and rear walls of the panel, said method comprising: removing said panel from said fairing;adhering fibers on one side of a vibration-damping nonwoven fabric to an exterior surface of the rear wall of said removed panel while leaving fibers on another side of said vibration-damping nonwoven fabric uncovered; andinstalling said panel with said adhered vibration-damping nonwoven fabric on said fairing with an exterior surface of the front wall of said panel being part of the exterior surface of the flight vehicle and said vibration-damping nonwoven fabric being exposed inside said fairing and not part of the exterior surface of the flight vehicle. 2. The method as recited in claim 1, wherein the fibers are made of polymeric material. 3. The method as recited in claim 2, wherein said polymeric material comprises aromatic polyamide. 4. The method as recited in claim 1, further comprising treating the fibers of said vibration-damping nonwoven fabric with water repellant additive. 5. The method as recited in claim 1, wherein said fairing comprises a pair of wheel wells, said panel being located aft of the wheel wells. 6. The method as recited in claim 1, wherein said fairing is a component of an aircraft. 7. The method as recited in claim 1, wherein said fairing is a component of a spacecraft. 8. A method for assembling a flight vehicle fairing, comprising: obtaining a panel that comprises front and rear walls and a honeycomb structure at least partially filled with foam and/or particles and disposed between the front and rear walls of said panel;adhering fibers on one side of a vibration-damping nonwoven fabric to an exterior surface of the rear wall of said panel while leaving fibers on another side of said vibration-damping nonwoven fabric uncovered; andinstalling said panel with said adhered vibration-damping nonwoven fabric on said fairing with an exterior surface of the front wall of said panel being part of the exterior surface of the flight vehicle and said vibration-damping nonwoven fabric being exposed inside said fairing and not part of the exterior surface of the flight vehicle. 9. The method as recited in claim 8, wherein the fibers are made of polymeric material. 10. The method as recited in claim 9, wherein said polymeric material comprises aromatic polyamide. 11. The method as recited in claim 8, wherein said fairing is a component of an aircraft or a spacecraft. 12. The method as recited in claim 8, wherein said fairing comprises a pair of wheel wells, said panel being located aft of the wheel wells. 13. A fairing for a flight vehicle comprising a multiplicity of panels, at least one of said panels comprising front and rear walls and a honeycomb structure at least partially filled with foam and/or particles and disposed between the front and rear walls of said panel, further comprising a vibration-damping nonwoven fabric that comprises fibers on one side which are adhered to an exterior surface of the rear wall of the panel and fibers on another side which are uncovered, wherein an exterior surface of the front wall of the panel forms part of the exterior surface of the flight vehicle and said vibration-damping nonwoven fabric is exposed inside said fairing and not part of the exterior surface of the flight vehicle. 14. The fairing as recited in claim 13, wherein said fibers are made of polymeric material. 15. The fairing as recited in claim 14, wherein said polymeric material comprises aromatic polyamide. 16. The fairing as recited in claim 13, wherein said vibration-damping nonwoven fabric is water repellant. 17. The fairing as recited in claim 13, further comprising a pair of wheel wells, said panel being located aft of the wheel wells. 18. The fairing as recited in claim 13, wherein said flight vehicle is an aircraft or a spacecraft.
