Which of the following is a component of an afterburner?

An afterburner, also known as a reheat, is designed to increase the thrust of a gas turbine engine by injecting additional fuel into the hot exhaust gases after they have passed through the turbine. The inclusion of fuel nozzles or spray bars is essential because they are responsible for atomizing and injecting this additional fuel into the exhaust stream. When this fuel combusts, it significantly raises the temperature and velocity of the exhaust gases, resulting in increased thrust.

The fuel nozzles or spray bars are strategically positioned to ensure efficient mixing of the fuel and exhaust gases, promoting optimal combustion. This design allows for a simple yet effective method of boosting performance, especially in military applications where increased thrust during combat maneuvers is vital.

Other components mentioned, like engine compressors, intake manifolds, and throttle bodies, play roles in the overall operation of a gas turbine engine but are not directly involved in the afterburner functionality itself. The correct answer emphasizes the specific components that contribute to the afterburner's unique process of enhancing engine performance post-combustion.
