Spark Igniter
A spark igniter is a device that creates a high-energy electrical spark to ignite the fuel-air mixture in a jet engine, rocket engine, or gas turbine, similar to a spark plug in a car.
TECHNICAL DEFINITION
A spark igniter is an electro-mechanical component in aerospace propulsion systems designed to generate a high-voltage, high-energy electrical discharge across an electrode gap, initiating the combustion of fuel-air mixtures within a combustion chamber during the engine startup sequence.
BACKGROUND
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, burner can, combustion chamber or flame holder. In a gas turbine engine, the combustor or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of ramjet or scramjet engines, the exhaust is directly fed out through the nozzle.

USAGE NOTE
Spark igniters are primarily used during engine startup and re-light attempts in flight, and are typically not continuously operated once combustion is stable.
