1. General
The air entering by the fan is divided into two parts, the cold and hot airflows, which are mixed through the common nozzle assembly (CNA) before exhausting to the atmosphere.
The engine exhaust section directs fan discharge air to either normal or reverse thrust operation. In the forward thrust mode, the fan airflow and burnt gases are evacuated directly at the back.
Each engine is equipped with a reverser system which reverses cold fan air by means of translating sleeves and cascades, turning the engine airflow forward and providing a braking effect for the aircraft on the ground.
Thrust reversers can be operated on the ground only.

3. Description
The exhaust system consists of the common nozzle assembly and the thrust reverser system.
The exhaust system consists of the common nozzle assembly and the thrust reverser system.
A. Common Nozzle Assembly (CNA)
The common nozzle assembly forms the rear part of the engine.
It consist of a common nozzle exhaust collector and the engine exhaust cone.
The common nozzle assembly forms the rear part of the engine.
It consist of a common nozzle exhaust collector and the engine exhaust cone.
B. Thrust Reverser System
The thrust reverser system uses part of the engine exhaust power to provide additional aerodynamic braking during aircraft landing.
The thrust reverser system is hydraulically operated by hydraulic pressure from the aircraft hydraulic system. The aircraft hydraulic system is pressurized by pumps mounted on each engine.
It is controlled through the FADEC (Full Authority Digital Engine Control) from the cockpit by a lever hinged to the corresponding throttle control lever.
