Aeroplane doesnt have a reverse gear, why?

Answer 1

Jet aircraft have reverse thrust which is a scheme like two clam shells that swing in behind the engine's outlet to direct the hot gasses forward to provide faster braking when landing.

Contrary to another answer, reverse thrust is not used to back away from a gate. It could be, but it would direct a very loud blast of very fast air towards the terminal windows, baggage handlers, etc. Low, heavy tugs push the jet back from the terminal at all but the most remote airport. At remote sites, the jets don't pull all the way in, but allow themselves a forward path out.

Most turboprops (propellors spun by a geared down turbine) have "beta" settings (versus forward "alpha" settings) for the same reason - faster stopping on landing. Very helpful on wet or icy runways on which the landing gear's brakes are minimally effective.

A friend up here ordered the wrong prop for his home-built craft. He specified diameter and pitch but not direction. Most planes have the engine forward but his was a pusher. He actually got it all installed and then noticed the prop blast was going the wrong way. The only 450-pound aircraft with beta!

A very few jets had electric motors to spin up the tires to reduce tire wear (when it goes from 0 to 170 mph in 0.1 seconds). But that power to the wheels never propelled the whole plane in either direction.

Answer 2

1. Before going back, the aeroplane should stand still in the sky, it is not possible.
2. There is no necessasity for having reverse gear. The aeroplane can go round in the trafficless sky and can reach its backward destination.
3. The aeroplane has reverse gear like mechanism to slow down the momentum while landing. But it can not be used to go back while flying.
4. If the aeroplant posseses main rotar as in helicoptors, the reverse gear is possible.
5. No conductor is available to guide the pilot in the aeroplane while moving back!!!! (just for joke).

Answer 3

a lot of goofy concepts above, and a pair of properly acceptable solutions. Jet airliners have thrust reversers, used to decelerate after touchdown; now and again those must be used to bypass backward on the floor. Many propeller pushed airplanes have reversible pitch propellers that must be used to sluggish the plane for the time of a steep descent or after touchdown. A propeller which will properly be reversed in flight is termed a "beta prop." It won't be able for use to fly backward. Reversible pitch propellers must be used to taxi backward. the priority with pushing decrease back in any plane, obviously, is that the guy on the controls won't be able to be sure the position she is going. So educated crew individuals on the floor and robust hand indicators are necessary. No plane can fly backward, except as an occasional stunt that relies upon on having a strong wind. We used to diminish back our DC-6s and Convair 240s robotically. i myself sponsored a DC-6 right into a hangar one time, with about six adult men giving hand indicators outside. So if that satisfies you that airplanes have "opposite gears," you at the instantaneous are extra perfect suggested. Have an mind-blowing day, and have a good time contained in the memory of the golden age of aviation. (Wasn't that some time previous. i became there, and that i'm nevertheless alive.)

Answer 4

They can't have a reverse gear. The wheels arent driven. Jets do have a thrust reverser, its used as an airbrake. And honestly, why would it need it for, if its JUST to get out of a gate, doesnt seem worth it. Plus aircrafts work on thrust alone. The wheels are casters for all intents and purposes.

Answer 5

Because airplanes need to stay in the air. Otherwise they...crash.

Airplanes can stay in the air because they're pulled or pushed forward by their engines. The way the air flows under their wings causes them to be pushed upwards, into the air (it's called "lift").

If, hypothetically speaking, you could stop an airplane's propeller in mid-flight and put it into reverse (which would only work on propeller driven aircraft, not jet powered ones), the airplane would drop out of the sky, because, for that brief instant, the propeller would no longer be propelling the airplane, and so the airplane would stop getting lift.

Plus, because of the way an airplane's wings generate lift, you can't get lift when you push an airplane backwards. Airplanes only fly when going forwards.

Answer 6

If you put a plane in reverse when it's in the air, it will fall out of the sky. The aeronautics industry believed it would be better to not take the chance of accidental reversal, so planes are built with no reverse capability.

Answer 7

they only have reverse thrusters on the engines which are activated for a few seconds during landing to help the plane lose more speed quickly

Answer 8

Because if it stopped going forward in the air it would fall before it could go backwards?

Answer 9

No place to put the rearview mirror.

Answer 10

because no-one wants to fly back to where they just came from.
