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

Edward Seymour Forman was an American engineer and inventor known for his pioneering work in early rocketry in the United States. Forman, along with his collaborators in Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT), demonstrated the first practical jet-assisted take-off (JATO) of an aircraft in the United States. Forman was among the GALCIT innovators that went on to found Aerojet General Corporation, the largest rocket technology manufacturer in the 1940s, and the GALCIT Rocket Research Group itself became the precursor of the Jet Propulsion Laboratory.
