Chapter 4: Engine Ignition & Electrical Systems › Turbine Engine Ignition Systems
Turbine Engine Ignition Systems Since turbine ignition systems are operated mostly for a brief period during the engine-starting cycle, they are, as a rule, more trouble-free than the typical reciprocating engine ignition system. The turbine ... engine ignition system does not need to be timed to spark during an exact point in the operational cycle. It is used to ignite the fuel in the combustor and then it is switched off. Other modes of turbine…
