What is one of the main functions of the tailpipe in the exhaust section?

• A. Increase thrust
• B. Regulate fuel flow
• C. Cool exhaust gases
• D. Direct exhaust flow

Answer: (D)

The main function of the tailpipe in the exhaust section is to direct exhaust flow. In a gas turbine engine, after the combustion process, the exhaust gases exit the turbine and must be efficiently channeled away from the engine. The design of the tailpipe helps to streamline the flow of these gases, ensuring they are expelled with minimal turbulence and loss of energy. Properly directing the exhaust flow is crucial for optimizing engine performance and enhancing the overall efficiency of the propulsion system. It also plays a role in controlling the speed and pressure of the exiting gases, which is essential for generating thrust. While the tailpipe does not directly increase thrust or regulate fuel flow, its function in managing exhaust flow is fundamental to the effective operation of the gas turbine engine.
