What are the three types of shaft design in a gas turbine engine?

• A. Single, dual, or radial
• B. Single, parallel, or horizontal
• C. Single, split, or twin spool
• D. Single, combined, or split system

Answer: (C)

The correct answer identifies the three types of shaft design commonly found in gas turbine engines, which are single, split, or twin spool configurations. In gas turbine engines, the shaft design is crucial for determining how power is transmitted throughout the engine. A single spool system consists of one shaft that connects the compressor and turbine, which simplifies the design but can limit the efficiency and performance of the engine at various speeds. A split spool design features independent shafts for the low-pressure and high-pressure components, allowing for improved performance and efficiency, especially at different operating conditions. Twin spool systems provide a more sophisticated approach, using two turbine and compressor assemblies that can operate at different rotational speeds, enhancing overall engine flexibility and efficiency. Understanding these shaft designs is essential for tasks related to engine operation, maintenance, and troubleshooting within the context of gas turbine technology.
