What type of gas turbine cycle configuration is shown in the illustration? Illustration GT-0031

Correct Answer: Option D — Intercooled-recuperated type.

The illustration depicts an intercooled-recuperated Brayton cycle configuration. This design utilizes an intercooler to reduce compressor work and a recuperator to recover exhaust heat, significantly increasing the overall thermal efficiency of the gas turbine plant compared to simple cycle arrangements, which is critical for marine propulsion fuel economy.
