Abstract
A fuel cell for containing fuel for an aircraft has a side wall including an innermost layer configured to contact the fuel and an outermost layer. A containment gel patch is coupled to the side wall of the fuel cell. The containment gel patch is formed from isocyanate and polyol. In addition, the containment gel patch is configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.
Claims20
A fuel cell for containing fuel for an aircraft, the fuel cell comprising:
- a side wall including an innermost layer configured to contact the fuel and an outermost layer;
- and
- a containment gel patch coupled to the side wall of the fuel cell, the containment gel patch formed from isocyanate and polyol, the containment gel patch configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.
An aircraft comprising:
- a fuselage;
- a propulsion system powered by fuel;
- and
- one or more fuel cells configured to store the fuel, each fuel cell comprising:
- a side wall including an innermost layer configured to contact the fuel and an outermost layer;
- and
- a containment gel patch coupled to the side wall of the fuel cell, the containment gel patch formed from isocyanate and polyol, the containment gel patch configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.
