When going at the speeds planes have to go to maintain altitude, brakes on the wheels can't properly slow down the plane, and even when they can, they have to take quite a bit of physical abuse. Thrust reversers, on the other hand, don't harm much of the plane, and work even as the plane bounces slightly from touch-down.

What is the function of the thrust reversers?

The function of the thrust reversers block thrust going reward and directs it forward to slow down the aircraft while landing.


How are breaks applied in jet engines?

A jet engine has no brakes. Though they do have thrust reversers which change the direction of thrust to slow the aircraft down. Aeroplanes have brakes on the wheels.


Why thrust reversers instead of aircraft braking system?

Thrust reverser systems are featured on many jet aircraft to help it slow down just after touch-down. This reduces wear on the brakes and enables shorter landing distances.


Do aircraft have brakes?

Yes. Aircraft have wheel brakes just like the brakes on your car. The pilot operates them by depressing the tops (or toes) of the rudder pedals. In addition, the flaps are used to slow the aircraft in flight, and many aircraft have air-brakes and/or thrust reversers to further aid in slowing the aircraft.


What is a cascade vane?

They are two panels behind the cowling that slide backward and reverse only the fan thrust (the fan produces the majority of the thrust). Fan air redirection is performed by devices called "blocker doors" and "cascade vanes". This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe. The reversers are used to slow the aircraft more quickly and reduce wear on the wheel brakes.


Do commercial jets always have to use reverse thrust?

No, but they will require a much longer runway if they plan to land without thrust reversers.


What is thrust in an aircraft?

Thrust is the power made by a jet engine to propel an aircraft.


What does thrust do to an airplane?

Thrust drives an aircraft forward.


What causes the thrust of an airplane?

The engine causes thrust, it moves the aircraft.


What is thrust for an airplane?

Thrust is the produced force of the aircraft that propels the aircraft forward in order to overcome drag. Drag is the natural force of the air that resists the motion of the aircraft.


What is the source of the force of thrust for an airplane?

An engine is the usual source of thrust in an aircraft.


How does a parachute help stop the space shuttle?

It increases the amount of drag, since the space shuttle doesn't have thrust reversers like an airliner would.


How does thrust have an effect on an airplane?

Thrust causes an aircraft to roll forward, gaining wind pressure over the wings. When wind pressure is sufficient this will lift the aircraft.


Why does an airplane need thrust?

An aircraft needs an engine to get thrust and roll forward to gain lift.


What is a thrust for the jet engines?

The forward propulsion of an aircraft is called thrust.The thrust is given by the engines.


What is the relation between net thrust and gross thrust in a ramjet engine?

a net thrust is constant speed of an aircraft that dosent reduces.


What are the four forces on an aircraft and how do they act on an aircraft?

The 4 forces are defined as LIFT WEIGHT THRUST DRAG When an aircraft is cruising it is considered to be Lift = Weight / Thrust = Drag Lift = The amount of lift the wing produces Weight = The weight of the aircraft Thrust = The force the engine produces Drag = The resistance in the air - friction etc


What is the importants of thrust to weight ratio in aircraft?

It is important because it is essential for for climbing of aircraft. There is a limit for thrust to weight ratio. When an airplane exceeds it, it cannot climb effeciently.


How does lift and thrust help an airplane fly?

Lift keeps an aircraft up, thrust pushes it forward.


How do you back up a plane?

Most aircraft have an engine "reverser" function, which would propel thrust backwards. However, Jet Aircraft would use this only when landing to stop the plane at a high speed. Some Turboprop airliners like the ATR may use their reversers to propel themselves backwards, because they use a different mode to obtain thrust, which is via their propellers. However in most airliners, propelled by jet engines, they would be "pushed back" by a Pushback truck, which would line them up with the taxiway.


How are horsepower and thrust related in a jet aircraft?

The more horsepower you have, the more thrust you will be able to produce. The more horsepower you have, the more thrust you will be able to produce.

What does the engine on an airplane do?

They propel the aircraft by propellers or jet thrust.


Who does jet aircraft back up?

Jet aircraft push back from terminals by the use of a tug, which is just a tractor attached to the nose wheel. Jet engines also have thrust reversers which can be activated in some situations. Activating thrust reverse directs the propulsion of the engine forward causing the airplane to pivot along its vertical axis. The use of thrust reverse is normally recommended to aid breaking after landing and above certain speeds say 60 knots since at slow speeds it tends to kick off dirt which in turn gets ingested by the engine potentially causing damage.


What part of a plane and of a jet are used to create thrust?

The motors or engines. The propeller(s) generate forward thrust on piston or turbo-prop aircraft, and on jet aircraft, thrust is created both by combustion exhaust and by bypass air from the fan(s).
