Abstract

Systems and methods are provided for aircraft fire extinguishing with heated tubing. One example is a fire extinguishing system that includes a container configured to store a fire extinguishing agent, a tube configured to transport the fire extinguishing agent from the container to a compartment of the aircraft, and a valve configured to initiate a discharge of the fire extinguishing agent from the container and through the tube. The fire extinguishing system also includes a heating element thermally coupled with the tube, and a control member in a cockpit of the aircraft configured to directthe heating element to heat the tube prior to initiating the discharge of the fire extinguishing agent via the valve.

Description

technical field [0001] This disclosure relates to the field of aircraft, and in particular, to aircraft fire suppression. Background technique [0002] Aircraft may be equipped with fire suppression systems that spray chemicals into the engine compartment to extinguish flames. Traditional extinguishing agents such as Halon 1301 exhaust completely at low temperatures, so it can be used in situations where the agent can be exposed to cold weather and high altitudes to fight aircraft fires. However, these preparations are currently being phased out. Alternative agents are available that are effective in many ways in extinguishing fires, but do not perform as well at low temperatures as traditional agents. Therefore, aircraft manufacturers seek improved fire suppression performance at low temperatures. Contents of the invention [0003] The example described in this paper presents aircraft fire suppression with heated ducts. The heating element is thermally coupled to the ...
