Aircraft comprising a propulsion assembly and a fire-fighting system for the propulsion assembly

An aircraft comprising:

• a cockpit;
• at least one propulsion assembly, each propulsion assembly of the at least one propulsion assembly comprising a first compartment and a second compartment, the first compartment and the second compartment each comprising one or more fire zones;
• and
• a fire-fighting system dedicated to each propulsion assembly of the at least one propulsion assembly, each fire-fighting system comprising:
• two reservoirs, each reservoir of the two reservoirs containing an extinguishing agent;
• a control that is associated with each reservoir of the two reservoirs and is configured for actuation by a pilot, wherein, when actuated, the control is configured to open the reservoir with which the control is associated for releasing the extinguishing agent from the reservoir with which the control is associated;
• a bypass valve;
• a set of pipes connecting, through the bypass valve, each reservoir of the two reservoirs to each of the fire zones of the at least one propulsion assembly with which the fire-fighting system is dedicated;
• wherein the fire-fighting system is configured:
• to detect a fire in the at least one propulsion assembly to which the fire-fighting system is dedicated;
• and
• emit, when the fire is detected in the at least one propulsion assembly to which the fire-fighting system is dedicated, a fire alert signal for a visual or audible transducer situated in the cockpit;
• when a fire is detected in the one or more fire zones in the first compartment, to control the bypass valve to adopt a controlled state, in which, after activation of the control associated with one or both of the two reservoirs, the extinguishing agent in the one or both of the two reservoirs is expelled towards the one or more fire zones in the first compartment;
• otherwise, to control the bypass valve to adopt a default state, in which, after activation of the control associated with one or both of the two reservoirs, the extinguishing agent in the one or both of the two reservoirs is expelled towards the one or more fire zones in the second compartment.
