Systems for suppressing adverse exothermic reactions in an energy storage container. One energy storage system includes a container configured to support a plurality of battery cells; a plurality of battery cells disposed inside and supported by the container; an agent supply port attached to the container; and a tube disposed inside the container and having a closed end and an open end. The open end of the tube is in fluid communication with the agent supply port. The tube comprises fusible portions which are designed to melt or soften at a temperature which is lower than the melting or softening temperature of another portion of the tube. In response to melting or softening of the fusible portions of the tube, pressurized exothermic reaction-suppressing agent is distributed inside the container via the tube.

Systems for suppressing adverse exothermic reactions in energy storage containers

A fire suppression system for an aircraft having a compartment, the fire suppression system including an inert gas source in selective fluid communication with the compartment and a fire suppression agent source in selective fluid communication with the compartment, wherein an inert gas from the inert gas source and a fire suppression agent from the fire suppression agent source are at least partially combined to form a fire suppression mixture.

Aircraft fire suppression system and method

An example unit load device inerting system includes a nitrogen generation system, a first conduit coupled to the nitrogen generation system to carry nitrogen, an inlet located downstream of the first conduit and attached to a unit load device to deliver the nitrogen into the unit load device, an outlet attached to the unit load device, and a second conduit coupled to the outlet to carry gas out of the unit load device. An example method includes flowing nitrogen through a first conduit from a nitrogen generation system to an inlet located downstream of the first conduit and the inlet is attached to a unit load device to deliver the nitrogen into the unit load device, and venting the unit load device to transport gas out of the unit load device through a second conduit coupled to an outlet configured to be attached to the unit load device.

Systems and methods for flammability reduction and ventilation using nitrogen-enriched gas for transportation vehicle protection

A cargo-fire-suppression agent distribution system and methods are presented. A fire-warning signal indicating presence of fire in a cargo compartment onboard a class E cargo aircraft at a first altitude is received. An initial fire-suppression agent is distributed in the cargo compartment at the first altitude sufficient to suppress fire for an initial fire suppression time interval during a depressurization phase during which the class E cargo aircraft flies to a second altitude below the first altitude. A re-enforcing fire-suppression agent is distributed in the cargo compartment during a re-pressurization phase when a cabin altitude is below a predetermined cabin pressure level (PL) during which the class E cargo aircraft flies from the second altitude to a landing, after the initial fire-suppression time interval elapses. The re-enforcing fire-suppression agent distribution is maintained during a re-enforcing fire-suppression time interval.
