Do jet aircraft reverse their engines when they land.?

Answer 1

No - they redirect their thrust.

The turbines continue to turn in the same direction - but the engine thrust direction is changed so it is directed forwards rather than backwards.

(Ex Airforce)

Answer 2

No, they don't. Some, not all, can however reverse the thrust that the engines produce after the nose landing gear has touched down.

Many turboprops reverse the pitch of their propellers so that the air is forced straight ahead, and two systems for turbojets as well as turbofan aircraft divert the flow of air and exhaust from the engine forward to help the aircraft slow, called thrust reversers or "TR's."

One system, the clam shell type, actually has panels on the aft section of the engine that swing back and close behind the engine to form a "clamshell" or basically a big bucket that directs the thrust forward.

The other system frequently seen on jets is the cascade reverser, which employs some of the aspects of the clamshell reverser. On this type, the section of the nacelle moves aft, moving semi-clam shells into the air that by-passes the combustion chamber of turbofan engines and directs that air through a grid of louvers towards the front of the aircraft.

Not all jets have them, and not all propeller planes can reverse pitch the props. And I don't know of any that can do it in flight, they all do it after all three landing gear are on the ground.

Answer 3

they reverse the thrust but not the engines. You can't reverse a jet engine.

Some jets don't seem to USE reverse thrust on landing though. For instance I am in a eurojet quite often and I think they just have really good brakes!

Answer 4

the engine is not reversed. They are called thrust reversers witch on landing can be deployed redirecting the trust of the engine to slow the aircraft down

Answer 5

they don't really reverse there engines but rather use a system called t/r (Thrust reversers) which take the air flow and pushes backwards causing it to slow or stop the aircraft much of the new planes now a days have this system to help them on landing

Answer 6

Airliners use "thrust reversers" after landing, to redirect engine thrust forward. This is because the engines, even at idle, are producing some unwanted forward thrust. The pilots can just reverse the idle thrust, or they can add more power to use the reverse thrust to help slow the plane down. That depends on how long the runway is and how quickly they need to stop.

Answer 7

NO. some aircraft have the ability however to point the thrust (or exhaust gases) in the opposite direction which is called thrust reverse! the harrier aircraft has the ability to vector thrust straight downwards and therefore hover (this is without getting too technical)

Answer 8

No They set out deflectors inside the engine which cause the fast high pressure airflow to be deflected and therefore instead of the airflow being directed through the exhaust of the engine it hits this directers, the air bounces of in to opposite direction to the exhaust causing the velocity of the aircraft to slow down by producing trust to the opposite way its moving.

Answer 9

If it were possible for a jet to reverse its engines there would be an almighty explosion can you imagine something which is capable of 16000 rpm and going into reverse in a couple of seconds. I think you meant reverse thrust! the answer to this is yes (ex flyer)

Answer 10

No they do not. They use whats called reverse thrust.Put your hands over your mouth and blowyou will feel the air to your cheeks. It blows the jet air towards the front which is used to slow the plane down

Answer 11

they dont reverse engines. its called reverse thrust. also spoilers, or speed brakes, deploy. the reverse thrust is when two little doors close over the exhaust side of engine. this creates a v shape when doors are closed, this causes the thrust to be redirected, causing the plane to slow down.
