Q

What is the power source for the ignition exciter of a gas turbine engine?

🔍 Key Concepts

• Typical ignition system design in aero-derivative and marine gas turbines • Difference between continuous ship power supplies (AC/DC buses) and localized ignition supplies • Why ignition systems need high reliability and independence from specialized/less-common ship systems

💭 Think About

• Think about which power source is most likely to be readily available everywhere on the ship where a turbine might be installed • Consider which choice would make the ignition system simple, robust, and easy to supply during starting without needing a special frequency source • Ask yourself which power source is commonly used to feed control and starting circuits on many marine propulsion systems

✅ Before You Answer

• Check which of the options is a standard ship service voltage used widely for controls and auxiliaries • Consider whether a 400 Hz system is common on typical merchant ships or more associated with aircraft/aviation systems • Verify which system would allow ignition exciters to work even if some AC services are disrupted, focusing on reliability of starting power
