A system includes a turbo pump to convert compressed gas into power, a storage tank to store the compressed gas, and a fire suppression control valve having a closed position in which the compressed gas is prevented from flowing to the cargo compartment and an open position in which the compressed gas is ported to the cargo compartment to suppress a fire. The system also includes a pump control valve having a closed position in which the compressed gas is prevented from flowing to the turbo pump and an open position in which the compressed gas is ported to the turbo pump to cause the turbo pump to convert the compressed gas into the power. The system also includes an OBIGGS to convert bleed air from a gas turbine engine into an inert gas to provide low rate discharge (LRD) fire suppression to the cargo compartment.

A fire suppression system for an enclosed space, such as within a lavatory of a vehicle, includes a first inner gate, a second inner gate coupled to the first inner gate to define one or more air channels therethrough, and a temperature-responsive device coupled to one or both of the first inner gate or the second inner gate. The temperature-responsive device is configured to be in a first state below a predetermined temperature threshold, and a second state above the predetermined temperature threshold. In the second state, the second inner gate is moved relative to the first inner gate to close the one or more air channels.

A vehicle includes an internal cabin. An enclosed component is within the internal cabin. The enclosed component includes an intumescent coating. As an example, the enclosed component is a lavatory within the internal cabin. As another example, the enclosed component is a waste compartment. As another example, the enclosed component is a grille within a door.

A fire-fighting vehicle includes a boom assembly movably coupled to a chassis, a penetrating nozzle coupled to the boom assembly, an actuator that moves the penetrating nozzle relative to the chassis, and a controller operatively coupled to a sensor. The penetrating nozzle includes a piercing tip and an outlet configured to be selectively fluidly coupled to a supply of fire suppressant. The piercing tip is repositionable relative to a surface of an object having an interior cavity. The outlet supplies fire suppressant into the interior cavity when the piercing tip is within the interior cavity. The sensor provides data relating to at least one of a position and an orientation of the piercing tip relative to the surface. The controller determines an angular orientation of the piercing tip relative to the surface based on the data.

A system and method for providing inerting gas to a protected space is disclosed. The system includes an air separation module that includes an air inlet, a membrane with a permeability differential between oxygen and nitrogen, a nitrogen-enriched air outlet, and an oxygen-enriched air outlet. The system also includes an air flow path between an air source and the air separation module inlet, and an inerting gas flow path between the air separation module nitrogen-enriched air outlet and the protected space.
