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 nozzle includes an inlet end having one or more inlet apertures and an outlet end having one or more outlet apertures. The nozzle includes a body member that extends between the inlet end and the outlet end. In some embodiments, the nozzle includes a central member that extends centrally through the body member. The nozzle includes an end member fixedly coupled with the central member at the outlet end. The nozzle includes a slidable member translatably coupled with the central member. The slidable member is configured to direct fluid that flows through the body member outwards towards an inner surface of the body member and translation of the slidable member adjusts a K-factor of the nozzle.

Fuel tank inerting systems are described. The systems include a fuel tank, a catalytic reactor arranged to receive a reactant mixture comprising a first reactant and a second reactant to generate an inert gas to be supplied to the fuel tank to fill an ullage space of the fuel tank, a condenser heat exchanger arranged between the catalytic reactor and the fuel tank and configured to cool an output from the catalytic reactor, and a fan assembly arranged within an inerting system flow path upstream of the catalytic reactor, wherein the fan assembly is arranged within a gas flow having a temperature of at least 185° C.

A fire fighting training unit formed of steel plate with a stackable first story, second story and a roof mounted at eye level on a portable mobile stand for use with a thermal imaging camera. The roof is stackable on either the first story or second story. Each of the first and second stories has a hallway formed by divider panels separating first and second burn units, said hallways simulating a stairway when the first and second stories are stacked. Apertures in the divider panels have a sliding valve for controlling airflow. A garage with a base and a stackable roof is attached to the first story by a breezeway with a rotary valve in a sleeve for controlling airflow between the first story and the garage. The roofs having an aperture and the first and second burn units of the first and second stories have windows with latched closures.
