Which of the following is not a component of a typical turbine exhaust nozzle?

A throttle body is a component typically found in internal combustion engines, where it regulates the flow of air into the engine's cylinders. In contrast, a turbine exhaust nozzle is designed to direct the flow of exhaust gases from the turbine's combustion chamber after the energy has been extracted.

The exhaust duct directs the flow of exhaust gases, allowing them to exit the engine efficiently. The tail cone improves aerodynamic efficiency and also helps to stabilize the exhaust flow. Support struts are utilized to provide structural support to the nozzle assembly. These components work together to manage the exit of exhaust gases, ensuring optimal performance and efficiency of the turbine. Therefore, since the throttle body is associated with controlling air intake in piston engines rather than exhaust management in turbine engines, it does not belong to the components of a turbine exhaust nozzle.
