How does a thrust reverser work?

How Does a Thrust Reverser Work? A thrust reverser is contained within the nacelle system, an aerodynamic structure surrounding the jet engine. To slow down after landing, the aircraft engine itself does not run in reverse; rather, the direction of the engine’s fan airflow is reversed, creating a massive drag.

What is the purpose of thrust reverser?

Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines.

How is the thrust reverser mechanism in a jet engine?

This mechanism consist a pair of nested screw jacks commonly driven by a drive motor. The inner screw jack translates the blocker doors aft and the outer screw jack deploys the blocker doors into the engine jet stream.

Which is more efficient Reverse thrust or maximum thrust?

Engine power reverse thrust characteristics can be drawn as per the rated rpm and % of rated Thrust, it is observed that Reverse thrust is max at higher speeds of Engine. So, Thrust reversers are more efficient at higher engine rpm.

Where are the doors on a thrust reverser?

A thrust reverser includes a pair of doors covering corresponding portals in an exhaust duct between an inlet and outlet nozzle at opposite ends thereof. The duct also includes a pair of side beams having actuators mounted thereon, and operatively joined to the doors for selective rotation thereof about corresponding pivots.

How did the thrust reverser malfunction on Flight 402?

The safety system automatically cut the power to the engine suffering the thrust reverser malfunction. There was no alarm or other indication in the cockpit to indicate that a thrust reverser had been accidentally deployed. The crew had no way of knowing what the true problem was.
