Engine Gas Turbines (Supplementary) USCG Question #64 (Set 2)

In the ignition system of a GTE, how is optimum spark achieved?

Official USCG Answer & Rule Citation

Correct Answer: Option B — Concentration of maximum energy in minimum time

Optimum spark intensity in a gas turbine is achieved by discharging the stored energy in the capacitor in the shortest possible time. This high-energy, short-duration pulse ensures that the spark can jump the gap even in the presence of fuel spray and high-velocity air currents.
