Will it Fly?

A plane (any plane, cessna, jumbo jet, C-5A Galaxy, doesn't matter) is sitting on a moveable runway - a 10,000 foot long conveyor belt. The plane is not secured to the conveyor or the ground in any way. The wind conditions are dead calm, 0 mph wind speed. From a dead stop, the pilot applies full power and releases the braKes. As the plane moves in one direction, the conveyor moves in the opposite direction. As the plane accelerates the conveyor is able to precisely match the speed of the plane in the opposite direction.

Will the plane be able to take off?

btw im pretty sure a few people in here with aviation in their blood will respond.......

Re: Will it Fly?

Yes
Well actually it's a trick question. A jet will move forward on a conveyor regardless. It doesn't apply any power to the wheels, so it would still move across the conveyor. A plane applies it's power to the air, not the ground.

There is no physical way to match the speed of a jet using a conveyor b/c the jet applies no power to the ground. So yes, it will take off.

Re: Will it Fly?

The aircraft has engines that through action/reaction principles cause it to accelerate in relation to the AIR not the belt. As the aircraft starts to move the belt will move in the opposite direction, the only effect this will have is to increase the speed of rotation of the tires, the plane will continue to accelerate in relation to the air and the ground beside the moving belt no matter how fast the belt moves. This may have detrimental effects on the tires but will not detrementally affect the AIRSPEED of the plane. In fact, air entrained by laminar boundary layers on the belt may actually inhance the airflow to the wings, shortening the takeoff run. Depends on how long the landing gear legs are. In the 60's a plane was built with a hovercraft type skirt instead of regular gear, this plane wouldn't even notice the increasing speed of the belt

Re: Will it Fly?

Nope, the laminar flow from the belt is near to nothing. The reynolds number of the belt is wayyy too low to make a difference.

Re: Will it Fly?

only if there's a lightning storm and the plane gets hit with 1.21 gigawatts, then it will have enough power to fly.

just lengthen the injection pulse, tune the Nos timer and you'll be running 9's....oh wait that's vtec. nm.

Re: Will it Fly?

im guessing no. doesnt a plane need the wind pressure thing on the wings to lift the plane? if its on a conveyer belt, the wind might not necessarily pick up high enough to lift it.

Oh God not this one again. IT WILL FLY DAMMITTOHELL!!!! Here is the reality we have to tie down C-130's because in a Hurricane they will lift off the ground and try to fly just sitting there.

Engines create the thrust and move the air

What keeps a plane flying while in air? Something has got to be moving the air. There is no runway.

Re: Will it Fly?

There is no way to create a moving runway that would keep up with the plane. The plane is applying no force to the tires to move, it is applying force using the engine, either the prop or the jet engine to move. This is why you can put pontoons on the bottom of a plane and take off on water.
Basically...whether or not the wheels are actually taking the plane anywhere, it is still moving air and moving through the air. It would take a little work from the pilot. He would have to hold the plane down till enough force is mustered up and then tilt up, but yes, the plane will take off.
BTW, I'm using my roommate (Aerospace engineer) for my information, and corey knows what he's talking about as well.

Re: Will it Fly?

No, the plane will not fly. It will reach the end of the belt before getting enough lift to take off, fall in the huge canyon at the end of the lift and go up into a huge burst of flame.

It said the conveyor belt was 10,000 feet long. Didn't say where the plane was on it... so I'm just gonna assume 5 feet from the edge...

BTW... I'm voting maybe if it had VTEC, because you can do anything with VTEC. 5 feet would be plenty of room to take off then.

It is exactly the same. no matter what is going on with the wheels. The air lifts the wing and the props pull the aircraft forward. If the engines were at idle and the A/C was going backward it would not take off but since it is going forward or matching speed with the conveyor the air is passing under the wings creating lift and the ***** will fly and anyone who does not agree HAS NO CLUE!!!!

Remember this about 25 years ago flying from a airliner that spent 45 minutes going almost nowhere while at 20,000+ feet hitting headwinds of over 400 MPH. This was confirmed by radar as they remained stationary

yes it needs a lightning storm and needs to hit 80mph to work.

88mph I believe.

But I still say it'll do it with just VTEC.

lol i said vtec, not a flux capacitor.

and i knew it will fly, i just wanted to start a nice debate, theres a ****ing 5 page one over at stangnet(yes, i troll the ****hole called stangnet from time to time). the propeller/turbine is what provides forward movement, and thats not being restricted. the wheels and conveyor are irrelevant to eachother because they cancel eachother out.

aircraft read speed by the air moving around the airplane, not how fast the tires are moving on the pavement. lets take a cessna for example, say it needs to do 120 to take off. the moment the propellers spin and provide thrust, we bring the conveyor on. now well say theres a link between the airspeed indicator and conveyor mechanism that keeps them at the same mph. the thrust of the propeller will move the plane forward, because the wheels are free spinning, if the plane moves, the wheels do not resist it, only hold the plane up from bellying out on the runway. if the plane is going 20mph, the conveyor doing 20, the wheels are spinning at 40mph, but since the wheels are free spinning, they have no effect on the speed of the plane, which is moving at 20mph THROUGH the air. the plane has the same amount of ease as on a fixed runway to reach liftoff speed, it hits 120 no matter what surface is underneath, and takes off.

When this thing hits 88 mph.. we are going to see some serious ****.

Re: Will it Fly?

I think it can, depending on if there is enough thrust.

You are not understanding the scenario. Whatever the forward speed of the Aircraft it is matched by the speed of the conveyor. So your theory is moot

It is like this. Say this long conveyor was carrying the A/C at 150 mph as soon as he starts the engines and gets to where he is going 150 mph in the opposit direction he will be airborne

Does that help you?????
