Question 63Gas Turbine - Assistant Engineer
70% to passIn the ignition system of a gas turbine engine, how is optimum spark achieved?
AConcentration of minimum energy in maximum time.
BConcentration of maximum energy in minimum time.
CConcentration of maximum energy in maximum time.
DConcentration of minimum energy in minimum time.
AI Explanation
The correct answer is B) Concentration of maximum energy in minimum time. In a gas turbine engine's ignition system, the goal is to achieve a high-energy spark that can reliably ignite the fuel-air mixture. Concentrating the maximum amount of energy in the shortest possible time creates an intense, focused spark that is more effective at igniting the mixture compared to a lower-energy spark over a longer duration. The other options are incorrect because A) and C) would result in a less efficient spark that may struggle to reliably ignite the mixture, while D) would not provide enough energy to consistently ignite the fuel-air blend.
