Abstract : A new method of sealing integral fuel tanks was proposed. This method proposes that only one material be used to seal the external grooves, thus eliminating the prefabricated fillets and aerodynamic smoother. A mandatory property of the material selected is that it shall not extrude above the surface of the external skin AT HIGH TEMPERATURES. Two materials which show promise in this application are EC-1610 and EC-1610 (gray) sealants. These materials were evaluated in a small simulated wing tank to determine their sealing characteristics. Conclusion: EC-1610 and EC-1610 (gray) do not provide a seal equivalent to the seal presently used in B-58 production because of extrusion at high temperature. (Author)
