A flexible fuel bladder structure for an aircraft includes one or more sleeves extending along an exterior of the fuel bladder. The one or more sleeves are receptive of one or more rods to at least partially suspend the fuel bladder in the aircraft. An aircraft includes a fuselage and a flexible fuel bladder disposed in the fuselage. One or more rods are installed through a portion of the fuel bladder and into a fuselage member. The flexible fuel bladder is at least partially suspended from the one or more rods. A method of installing a fuel bladder in an aircraft includes inserting a flexible bladder into a fuselage space of the aircraft. One or more rods are installed through one or more fuselage members and one or more sleeves of the fuel bladder. The one or more rods at least partially suspend the fuel bladder in the fuselage.

1. A flexible fuel bladder structure for an aircraft comprising: one or more sleeves affixed to and extending along a top exterior surface of the fuel bladder, each sleeve extending continuously from a first lateral side to a second lateral side of the fuel bladder; andone or more rods extending through the one or more sleeves along the top exterior surface to at least partially suspend the fuel bladder in the aircraft, the one or more rods extending continuously through the one or more sleeves from the first lateral side to the second lateral side of the fuel bladder. 2. The fuel bladder structure of claim 1, wherein the one or more sleeves are formed integral with the fuel bladder. 3. The fuel bladder structure of claim 1, wherein the fuel bladder includes one or more additional fittings for suspending the fuel bladder in the aircraft. 4. An aircraft comprising: a fuselage;a flexible fuel bladder disposed in the fuselage; andone or more rods installed through a first fuselage member, through a portion of the fuel bladder and into a second fuselage member, the flexible fuel bladder at least partially suspended therefrom, the one or more rods extending continuously from the first lateral side to the second lateral side of the fuel bladder. 5. The aircraft of claim 4, wherein the fuel bladder includes one or more sleeves for installing the one or more rods therethrough. 6. The aircraft of claim 5, wherein the one or more sleeves are formed integral with the fuel bladder. 7. The aircraft of claim 5, wherein the one or more sleeves are disposed at a top portion of the fuel bladder. 8. The aircraft of claim 5, wherein each sleeve of the one or more sleeves extends from a first lateral side to a second lateral side of the fuel bladder. 9. The aircraft of claim 4, wherein the fuselage member is a keel of the fuselage. 10. The aircraft of claim 4, wherein the flexible fuel bladder is suspended beneath a deck of the aircraft. 11. The aircraft of claim 4, wherein the one or more rods are secured in position by one or more of a pin, cap or nut. 12. The aircraft of claim 4, wherein the fuel bladder includes one or more additional fittings for suspending the fuel bladder in the aircraft. 13. The aircraft of claim 12, wherein the one or more additional fittings are one or more vent fittings securable to one or more deck fittings of the fuselage. 14. The aircraft of claim 4, wherein the aircraft is a helicopter. 15. A method of installing a fuel bladder in an aircraft comprising: inserting a flexible bladder into a fuselage space of the aircraft; andinstalling one or more rods through a first fuselage member arranged at a first lateral side of the fuel bladder, through one or more sleeves arranged at an upper exterior surface of the fuel bladder and into a second fuselage member arranged at an opposite, second lateral side of the fuel bladder, thereby suspending the fuel bladder in the fuselage. 16. The method of claim 15, further comprising inserting the flexible bladder into the fuselage space through an access opening in a fuselage member of the one or more fuselage members. 17. The method of claim 15, further comprising installing one of a pin, cap, or nut at an end of the one or more rods to secure the one or more rods in position.
