The exhaust is made up of the collector/nozzle and thrust reverser. The collector/nozzle controls engine airflow to give thrust. The thrust reverser decreases the speed of the aircraft on the ground after landings and during aircraft taxi.

The collector/nozzle collects the bypass air from the fan and exhaust gases from the turbine, and sends the gas and the air overboard. The mixture of warm and cold air increases the jet speed while it decreases the higher core speed. This also decreases noise and uses fuel more efficiently.

The collector/nozzle uses an exhaust mixer nozzle and center body with a core plug cover to mix the air and gases. The center body is in the shape of a cone for decreased weight and easy installation.

The exhaust mixer nozzle is a circular structure with a flange at the front end which attaches to an external flange on the engine turbine section. The center body is an open end cone with an internal flange at the front end. This flange attaches to the core plug cover and to an internal flange on the engine turbine section. The exhaust mixer nozzle and the center body make an annular duct through which the exhaust gases flow out of the engine core.

When the thrust reverser is stowed, the exhaust gases and air flow from the collector/nozzle through the thrust reverser overboard rearward of the engine. This gives a forward thrust to the aircraft. When the thrust reverser is deployed, two pivot doors extend and change the flow of the exhaust gases and air to a forward direction. This causes a thrust in the opposite direction to decrease the aircraft speed which is necessary after landings.
