Fire suppression system and method for fire suppression in an airborne vehicle

摘要

The present invention pertains to a fire suppression system and a method for fire suppression in an airborne vehicle, particularly in cargo bays of aircraft. The fire suppression system comprises a fuel tank inerting system including at least two on-board inert gas generating systems, a halon-based fire suppression subsystem configured to release halon as a first fire suppression agent, a monitoring module, which is coupled to the at least two on-board inert gas generating systems, and which is configured to monitor the operability of the at least two on-board inert gas generating systems and to output a monitoring signal indicating the state of operability of the at least two on-board inert gas generating systems, and a control module, which is coupled to the monitoring module, the at least two on-board inert gas generating systems and the halon-based fire suppression subsystem, and which is configured to select one of the at least two on-board inert gas generating systems depending on the monitoring signal and to control the selected on-board inert gas generating system to release an inert gas as a second fire suppression agent.
