Various embodiments of the present invention provide a system and method for notifying a flight crew of a fire condition in a cargo container of an aircraft. For instance, particular embodiments involve installing at least one notification device on a cargo container that is in communication with at least one of a fire-detection system or a fire-suppression system for the cargo container. In these particular embodiments, the notification device is configured to emit energy when the fire-detection system detects the fire condition in the cargo container or the fire-suppression system activates as a result of the fire condition. Further, particular embodiments of the invention involve installing at least one detector positioned to detect the energy emitted by the notification device. In these particular embodiments, the detector is configured to send a signal to notify the flight crew of the fire condition after detecting the energy emitted by the notification device.

Overheat and fire detection for aircraft systems includes an optical controller and a fiber optic loop extending from the optical controller. The fiber optic loop extends through one or more zones of the aircraft. An optical signal is transmitted through the fiber optic loop from the optical controller and is also received back at the optical controller. The optical controller analyzes the optical signal to determine the temperature, strain, or both experienced within the zones.

An onboard electrochemical system of an electrochemical cell including a cathode and an anode separated by an electrolyte separator is selectively operated in either of two modes. In a first mode of operation, water or air is directed to the anode, electric power is provided to the anode and cathode to provide a voltage difference between the anode and the cathode, and nitrogen-enriched air is directed from the cathode to an aircraft fuel tank or aircraft fire suppression system. In a second mode of operation, fuel is directed to the anode, electric power is directed from the anode and cathode to one or more aircraft electric power-consuming systems or components, and nitrogen-enriched air is directed from the cathode to a fuel tank or fire suppression system.

A thermal management system and method includes: a drive shaft; one or more fans or impellers in fluid communication with at least a portion of the drive shaft; and one or more air management baffles configured to direct air flow between the impeller and the portion of the drive shaft. In one embodiment, the system and method further includes insulation positioned about the at least a portion of the drive shaft.

A battery containment mesh includes a plurality of loops and a plurality of joiners that interconnect the loops into a net sized to surround a battery pack including a plurality of battery cells. The loops and the joiners are fabricated of heat resistant materials capable of maintaining physical integrity in an event of combustion of the battery pack such that the battery containment mesh can carry a weight of the battery pack after the event of combustion.

An aviation laminate includes an intumescent backer sheet covered by a decorative sheet. The aviation laminate is generally fire-resistant, may be structural, and may be used to construct various components within an aircraft cabin that may be held to government/regulatory fire mitigation requirements.

A mounting fixture for mounting a sensor circuit to a support rail is disclosed. In various embodiments, the mounting fixture includes a bracket having a base portion and a first flange member extending from the base portion; a clamp fixture connected to the first flange member, the clamp fixture including a plate member; a first pin extending through the first flange member and the plate member; and a first fastener threaded on to the first pin and configured to secure the plate member to the first flange member.

A sensing assembly comprising includes one or more sensing elements formed as a tube. The sensing assembly also includes one or more clamps to secure the one or more sensing elements. Each of the one or more clamps includes a recess in which each of the one or more sensing elements is seated.

A method for generating electrical energy by a fuel cell system operated with a reformate gas is provided. According to this method, a fuel cell system is provided. The fuel cell system has a first reactor and a second reactor. A gas separation unit is also provided. A portion of a first fuel gas is fed to the gas separation unit. A target gas including N.sub.2 or CO.sub.2 is separated by the gas separation unit. The separated target gas is fed into a protective housing of the fuel cell system. An H.sub.2-enriched tail gas formed in the gas separation unit is fed as a second fuel gas for operation of the fuel cell.
