||Spark igniter system failures are a leading cause of gas turbine engine removal from aircraft. To
insure relight in the event of engine shutdown at altitude, a high-voltage, high-energy spark is
required. The igniter is eroded by each discharge, limiting its lifetime under normal operating
conditions. Frequent engine startups shorten the igniter life. Nova Photonics, Inc proposes a
laser ignition system to replace existing electrical spark systems.
The igniter is based on a passively Q-switched solid state laser.|
||Provide reliable gas turbine engine startup with a low maintenance system. Commercial applications include jet engines and automotive market.
