The primary function of turbine ignition systems is to initiate fuel combustion in the engine. In gas turbine engines, the ignition system is crucial for ensuring that the fuel-air mixture inside the combustion chamber ignites properly to sustain the combustion process. This involves generating a spark or heat to ignite the fuel, allowing for a controlled and efficient burning of the fuel, which is essential for the engine's operation.

Once combustion is initiated, the process continues as long as there is a fuel supply and the conditions within the combustion chamber are suitable. The ignition system typically consists of igniters that are designed to withstand the high temperatures and pressures present in a turbine engine.

While regulating fuel flow is important for overall engine performance, this task is separate and occurs after ignition has been successfully initiated. Cooling engine components and enhancing thrust are other critical aspects of turbine operation but are not directly related to the initial ignition of the fuel. Thus, the ignition system's primary focus is specifically on starting combustion to enable the turbine's power generation.
