What powers the Thrust Reverse System in the engine?

The Thrust Reverse System in the A320 is powered by hydraulics. This means that hydraulic pressure is utilized to actuate the mechanisms that redirect the engine's thrust forward to help decelerate the aircraft after landing. Hydraulic systems are typical in modern aircraft because they provide strong force in a relatively compact and lightweight manner, making them ideal for controlling various applications, including thrust reversers.

The use of hydraulic pressure allows for precise and reliable operation of the thrust reversers, ensuring effective performance under the specific operational conditions encountered during landing. This system engages the thrust reverser doors to deflect the engine's exhaust, creating reverse thrust that aids in the slowing down of the aircraft.

While pneumatic systems, electric motors, and mechanical linkages all play important roles in various aircraft systems, they are not the primary source of power for the thrust reverse mechanism in the A320.
