Fuel leak combustion assembly for igniting a gaseous fuel leaking from a potential leak location

A fuel leak combustion assembly for an aeronautical vehicle, the aeronautical vehicle comprising a vehicle body, a gas turbine engine having a combustion section, and a fuel delivery assembly extending to the combustion section, the fuel leak combustion assembly comprising:

• a heat source physically enclosed with and positioned in communication with a potential leak location of a gaseous fuel delivery section of the fuel delivery assembly;
• and
• a controller in operable communication with the heat source configured to activate the heat source in response to obtaining data indicative of a gaseous fuel leak from the potential leak location to ignite a gaseous fuel leaking from the potential leak location of the gaseous fuel delivery section of the fuel delivery assembly;
• and
• a flame arrestor positioned between the potential leak location and the heat source, wherein the flame arrestor includes a perforated metal structure to dissipate heat from the heat source.

An aeronautical vehicle comprising:

• a vehicle body;
• a propulsion system operable with the vehicle body, the propulsion system comprising a gas turbine engine, the gas turbine engine comprising a combustion section;
• a fuel delivery assembly comprising a gaseous fuel delivery section extending to the combustion section, the gaseous fuel delivery section defining a potential leak location;
• and
• a fuel leak combustion assembly comprising:
• a compartment surrounding the potential leak location;
• a heat source enclosed within the compartment and positioned in communication with the potential leak location to ignite a gaseous fuel leaking from the potential leak location of the gaseous fuel delivery section of the fuel delivery assembly;
• and
• a flame arrestor positioned within the compartment and positioned between the potential leak location and the heat source, wherein the flame arrestor is positioned entirely around the potential leak location, and wherein the flame arrestor includes a mesh configured to absorb and dissipate heat from the heat source.
