PT6 Ignition
The Pratt & Whitney PT6 is a widely used turbine engine in the aviation market.
Keep them clean
When working with igniter systems, be sure to keep all the central conductors of the connections clean. Lubrication contamination of these central conductors can result in a high resistance path that can generate heat and oxidation, leading to the welding of the electrical components.
This has been a brief primer on PT6 ignition systems. Be sure to refer to the maintenance manual whenever performing any maintenance on the engine.
