Question 130Gas Turbine - Assistant Engineer
70% to passThe gas generating sections of marine gas turbine engines are based on which of the following?
AAircraft jet engines.
BRadial piston engines.
COil-fired auxiliary boilers.
DFree piston engines.
AI Explanation
The correct answer is A) Aircraft jet engines. Marine gas turbine engines are based on the same fundamental principles as aircraft jet engines. They use a gas generator section that compresses air, mixes it with fuel, and ignites the mixture to generate high-pressure, high-temperature exhaust gases that then drive a power turbine. This design is directly adapted from the architecture of aircraft jet engines. The other options (radial piston engines, oil-fired auxiliary boilers, and free piston engines) do not share this core gas turbine design approach used in marine gas turbine propulsion systems.
