A plane (747 passenger jet) is sitting on a runway that can move (some sort of band conveyor). The plane moves in one direction, while the conveyor moves in the opposite direction. This conveyor has a control system that tracks the planes speed and tunes the speed of the conveyor to be exactly the same (but in the opposite direction).

The question is:

Will the plane (747 passenger jet) take off or not?



*those of you who know it, and know where i got this, madmat.., shh..let em figure it out*

 

whats a conveyor ?

 

it will defidently take off once it gets a few red bulls in it

 

like a giant tread mill

 

It makes no difference as the tires on a plane are non functional, tires on a plane are self spinning. They are their to support the planes weight not produce any sort of thrust..

 

plane will not take off.
The planes wings needs air speed and the wing flaps tilt down to help lift off the ground while the turbines need air suction also for lift off..

so the answer is no.

that was my short answer...if u want more detail and wanna get technical let me know.

 

you sure about that?


go ahead get technical

 

yeah seriously getting all technical loooozes us simple minded people on the forum

 

The speeds needed for take off are relative to the motion of the air (air speed). A headwind will reduce the ground speed needed for take off. Typical take-off air speeds for jetliners are in the 130 to 155 knot range (150 to 180 miles/hour, 250 - 290 km/hour.) Light aircraft, such as a Cessna 150, take off at around 55 knots (63 miles/hour, 100 km/hour). Ultralights have even lower take-off speeds. The speed required varies according to many factors, including airport altitude, outside temperature, aircraft gross weight, power setting, and flap position. Pilots of multi-engine aircraft calculate a decision speed (V1) for each take off that dictates action to be taken in case an engine fails. Below V1 the take off is aborted; above V1 the pilot should continue to take off. The aircraft needs air speed. The wheels could be turning 3798272839 MPH on the conveyer belt, but the plane needs wind/airspeed to produce lift for the wing flaps...and the more air sucking into the turbines the greater the power for lift off.

 

what the **** did u just say

MR. technical

 

ill PM you the answer

 

lol..I have no clue..i just copied and pasted from some "how do airplanes take off site.." lmao

 

But its commen sense. How the hell can a plane take off while on a conveyer belt? the plane needs to be going into the WIND for lift off....it needs airspeed.


THIS THREAD SUX!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

just post the answer on the board...?

 

no i want to see what otehr people say, and i want to see if somone can figure it out

 

if the wheels dont power the plane than it can take off because of its jets, it dosnt need traction to get moving just needs power from the jet engines.

 

.......................................

 

maybe im not understanding the question...im thinking as if the plane is on a DYNO...like a car is on a dyno.....
the wheels are spinning, but the car is in one spot.

I cant see how a plane will take off..if there is no air speed....Wind needs to be blowing into the Jet turbines and wind needs to be hitting the wing flaps at the 130 to 155 knot range (150 to 180 miles/hour, 250 - 290 km/hour.)

 

with a car, the wheels are where the power goes to, the wheels determine how fast it goes

with an airplane, the wheels are free spinning, its the engiens that generate thrust causing it to go foward

 

i still think that it dosnt matter wheather or not the runway is moving. Its like this for example, if you had on ice skates and the ice under your feet was moving, like the conveyor belt, and you had a rope to pull youself to the opposite end that it is moving you would be able to make it because the rope(jet engine in the case above) is what is making you move, not the runway, all your ice skates are for(plane wheels) is for support...if thats not right than i dont know

 

can you PM me the answer

 

no no no no no no

 

the plane still needs to actaully be moving foward through the air for take off. PM me the answer NOWW!!!!!!!!!!!!!!!!! before i go psykosiz on your ***

 

I understand the fact that a airplanes wheels are free spinning, and thats its the thruster/jet turbines that makes a plane go foward...BUT...the plane still needs air-speed....WIND/FAST FLOWING air needs to be hitting the wings flaps for the plane to LIFT off the ground......

Do wee see JET CARS at the dragstrips taking off for flight? no..those cars go 734897432 mph down the track but stay on the ground because they dont have wings and wind flaps......get it?

 

well it does say that the plane is moving so as long as the thrusters are going it shouldnt matter how fast in the other direction the belt is moving. if it is moving dosnt that automatically mean that there is wind speed???

well it is a damn plane, it better have wings and wind flaps, otherwise it wouldnt be a plane....it would be a really big car

 

this is the dumbest thread ever
