Methods for determining likelihoods of ignition hazards

A method for determining a likelihood of an ignition hazard, comprising:

• receiving a current waveform for a lightning strike event at a conductive member that forms an interface with a decomposable member, the decomposable member comprising a series of adjacent nodes that extend outward from the conductive member;
• receiving a first contact resistance for a first node of the decomposable member located adjacent to an interface volume;
• at a first time stamp, based at least on the first contact resistance, determining a first pressure within the interface volume;
• after determining that the first node is completely depleted, receiving a second contact resistance for a second node, adjacent to the first node;
• at a second time stamp, based at least on the second contact resistance, determining a second pressure within the interface volume;
• and
• determining a maximum pressure per current waveform within the interface volume based on at least the first pressure and the second pressure.

A system for determining a likelihood of an ignition hazard, comprising:

• one or more processors;
• and
• one or more storage devices holding instructions executable by the one or more processors to:
• receive a current waveform for a lightning strike event at a conductive member that forms an interface with a decomposable member;
• receive material parameter inputs for the conductive member and the decomposable member;
• and
• based at least on one or more of the received material parameter inputs and further based on an energy from the current waveform:
• determining an amount of heating of the decomposable member following the lightning strike event, by at least determining an increase in a temperature of the decomposable member;
• and
• determine a quantity of volatiles generated within the interface volume following the lightning strike event;
• determine a total pressure generation within the interface volume based on the determined amount of heating and the determined quantity of volatiles;
• and
• output a probability of ignition hazard by the lightning strike event based on a comparison of the total pressure generation and a containment pressure threshold for the interface volume.
