Abstract: A fire detection system for monitoring an aircraft compartment and supporting a cockpit crew with taking remedial action in case of a fire alarm with a fire detector within the compartment; a monitoring system within the compartment to provide live monitoring data on cargo; a cargo tracking system configured to provide cargo data of the cargo; an aircraft control system configured to provide aircraft status data; a system control configured to assess a fire warning data, the cargo data and the aircraft status data and to provide a recommended remedial procedure based on the assessment in case the fire detector raises a fire alarm at least in an affected portion of the compartment; and a display device configured to display the live monitoring data and the recommended remedial procedure to the cockpit crew in case of a fire alarm

Abstract: A freight carrier configured to be received in an aircraft cargo hold, a system of one or more such freight carriers and a receiving platform, and a platform, are each provided. The freight carrier includes a floor element having a resting surface configured to lie on a floor surface of a cargo hold of an aircraft. The freight carrier is configured such that its resting surface can be moved over a floor surface in a floor plane. The floor element has a base element having a base surface. The base surface is situated on the base element such that the base surface faces away from the resting surface. The resting surface is provided with an arrangement to allow the freight carrier to be slid over the floor surface. The floor element has a cavity which extends toward the base surface between the front portion and the rear portion.

Abstract: An aircraft has: a cargo hold, a first fire-extinguishing agent container with a fluid-like fire-extinguishing agent, a first line section extending from the first container to the cargo hold, such that the fire-extinguishing agent can flow from the first container into the cargo hold, a controllable valve coupled to the first line section for controlling a flow of fire-extinguishing agent through the first line section, a concentration sensor arranged in the cargo hold for sensing a concentration of the fire-extinguishing agent in the cargo hold, and a monitoring unit. The concentration sensor is coupled to the monitoring unit for transmitting to the monitoring unit a concentration sensor signal representing the sensed concentration of the fire-extinguishing agent in the cargo hold. The monitoring unit is coupled, to the valve for controlling the valve. The monitoring unit is configured to control the valve on the basis of the sensed concentration.

Abstract: An airplane fire extinguishing system comprises an extinguishing agent storage unit with an activatable closing device, which makes possible, when active, an outflow of extinguishing agent from the extinguishing agent storage unit, and a supply line, connected with the closing device and an outlet opening, via which the extinguishing agent can be conducted from the extinguishing agent storage unit to the outlet opening, in order to eject it there for firefighting, wherein one or more sensor systems are present, by means of which a current airplane state can be determined, and a control unit, connected with the closing device and an actuatable input element, is present, via which the closing device can be activated, the control unit constructed and configured in such a way that the closing device is activated, as a function of the current airplane state, which exists at the time of an actuation of the input element.

Abstract: A system for extinguishing and suppressing a fire in an enclosed space includes a Halon storage container and a nitrogen generator that are both connected by a duct system to extinguishing nozzles arranged in the enclosed space. Halon is supplied as a first extinguishing agent from the container to achieve a rapid initial extinguishing of the fire. Nitrogen enriched air is supplied as a second extinguishing agent from the nitrogen generator to achieve a continuous long-term fire suppression, commencing simultaneously with or after the introduction of the Halon. The nitrogen generator may include a molecular sieve to continuously generate the nitrogen enriched air from an inlet flow of environmental air.

Abstract: A system for suppressing fire in an enclosed space, e.g. an aircraft cabin or freight compartment, includes nitrogen tanks and/or generators to rapidly supply a limited quantity of nitrogen with-a high flow rate, and a membrane system to supply an essentially unlimited quantity of nitrogen at a lower supply rate for a long duration. The membrane system includes a selectively permeable membrane that separates nitrogen gas from ambient environmental air that is supplied into the membrane system. Once a fire is detected, nitrogen is supplied from the nitrogen gas tanks and/or generators at a high rate to rapidly increase the nitrogen concentration and establish a reduced oxygen concentration (e.g. 12 vol. %) in the enclosed space. Then, nitrogen is supplied from the membrane system at a reduced rate for a long duration to maintain the reduced oxygen concentration in the enclosed space until the fire is extinguished by oxygen starvation.
