A dual-purpose bulkhead structure functions to support normal aircraft operational loads and to absorb energy in a controlled manner during a crash. An integral fuel tank comprises a fuel compartment and a crashworthy flexible fuel cell. The fuel compartment includes two dual-purpose bulkheads and crushable foam disposed between the sides of the fuel cell and the bulkheads and sides of the fuel compartment. The foam limits fuel pressure loads on fuel compartment bulkheads and sides during a crash, thereby preventing their failure.
A crashworthy aircraft fuel tank comprising: a fuel compartment formed by two bulkheads, two sides, and a bottom; the bottom of the fuel compartment serving as a portion of the outer skin of the aircraft; each bulkhead including a zone adapted to crush in a predictable, controlled manner when exposed to a compressive force exceeding a predetermined level; and a crashworthy flexible fuel cell disposed within the fuel compartment and supported by the bottom thereof; and the fuel compartment sides and bulkheads extending a substantial distance above said fu...
