Hydrogen combustion control system for a vehicle having a turbine engine

A combustion control system for a vehicle having a turbine engine, the combustion control system comprising:

• a fuel source providing a hydrogen fuel;
• a combustor having an igniter, the combustor operable to receive the hydrogen fuel and combust the hydrogen fuel via the igniter to generate combustion gases;
• a fuel delivery assembly extending from the fuel source to the combustor, the fuel delivery assembly providing the hydrogen fuel from the fuel source to the combustor;
• a first control system having a first update rate of between 12 milliseconds (ms) and 25 ms and operable to control one or more operating parameters of the turbine engine;
• and
• a second control system which is dedicated to and in communication with the combustor and operable to:
• receive an input from one or more hydrogen detectors;
• determine a presence of the hydrogen fuel in the combustor based on the input from the one or more hydrogen detectors;
• and
• control the igniter to provide a spark rate of at least twenty sparks per second in response to determining the presence of the hydrogen fuel.

• a combustor operable to receive the hydrogen fuel and combust the hydrogen fuel to generate combustion gases;
• a fuel delivery assembly extending from the fuel source to the combustor, the fuel delivery assembly providing the hydrogen fuel from the fuel source to the combustor, wherein the fuel delivery assembly includes a check valve to limit a flow direction of the hydrogen fuel;
• a purge system operable to purge the hydrogen fuel from the combustor, the purge system having a purge fluid entry point into the fuel delivery assembly that is downstream of the check valve and upstream of the combustor;
• a first control system having a first update rate of between 12 milliseconds (ms) and 25 ms and operable to control one or more operating parameters of the turbine engine;
• and
• a second control system in communication with the purge system, wherein the second control system is dedicated to the purge system.
