Aircraft fuselage and method for releasing a fuel tank from inside the aircraft fuselage in case of emergency as well as aircraft

A method for releasing one or more hydrogen fuel tanks from inside of an aircraft fuselage in case of detection of a hydrogen leak, the method comprising:

• releasably securing, using a mounting device in an inside of an outer structure of the aircraft fuselage, a sled device carrying the one or more hydrogen fuel tanks in the inside of the outer structure of the aircraft fuselage;
• detecting an occurrence of the hydrogen leak within the aircraft fuselage;
• opening a first release door, which is positioned on a lateral side of the outer structure of the aircraft fuselage and separates the inside from an outside of the outer structure of the aircraft fuselage;
• and
• when the occurrence of the hydrogen leak is detected within the aircraft fuselage, using the mounting device to disconnect the sled device from the aircraft fuselage, such that the sled device, as well as the one or more hydrogen fuel tanks attached to the sled device, can be released from the aircraft fuselage through the open first release door;
• the sled device comprising a first accelerator and a second accelerator;
• and
• the first accelerator and the second accelerator being attached to the sled device at opposite end regions of the sled device from each other and oriented in opposite directions from each other, such that, when the first accelerator is activated, the sled device is ejected from the aircraft fuselage through the first release door, and, when the second accelerator is activated, the sled device is ejected from the aircraft fuselage through a second release door.
