What type of fuel tank is the AFT Fuselage?

• A. Metal tank with welded seams
• B. Plastic tank with a coating
• C. Bladder cell within an aluminum tank
• D. Composite material tank

Answer: (C)

The AFT Fuselage fuel tank is indeed a bladder cell within an aluminum tank. This design is chosen for several reasons concerning safety, efficiency, and maintenance. Bladder cells are flexible bags that hold the fuel, allowing for a lighter structure and accommodating the various shapes of the aircraft's fuselage. The aluminum tank provides a sturdy and corrosion-resistant outer shell, ensuring that the bladder cell remains secure and protected from external conditions. The use of this combination minimizes the possibility of fuel leakage, which enhances safety during flight. Additionally, having a bladder cell inside the aluminum tank allows for easier maintenance since the bladder can potentially be replaced independently if damaged. This configuration offers robustness while also taking advantage of the favorable characteristics of both materials—aluminum for structural integrity and bladders for flexibility and weight reduction. The choice aligns well with the demands of modern aircraft designs, where maximizing space and weight efficiency is crucial.
