Edited by: MotherMoon on 18/09/2008 03:07:43 I'm to sleepy to be posting let me just say one thing.
you need wings for lift.
thrust will send something upwards but jets don't use thier engines to bolt in a straight line to take off, they use wings to catch the air and lift up off the ground. ONce in the air it takes less power, however without wings they would just spin and explode.

http://blag.xkcd.com/ <- Its down at the moment so i cant link you directly to the Blog regarding this "question", but it should be the newest entry anyways.
(Yes im lazy, i just post the link to someone who put the answer online instead of writing it myself. Bite me muwaha)

Edited by: Forge Lag on 18/09/2008 13:04:25 So the original question is: Can some generic plane cause surrouding air to move fast enough to cause sufficient uplift (while the plane is basically bolted to the floor)?
I guess it depends on the plane.
Also note that if the plane has wheels the belt would have to move extremly fast to compensate (it causes the plane to move through the low friction bearings in the wheels while the plane is braced against air with full force) and at such speeds it will cause some air movement too. Rather bolt the plane to the floor and measure it's weight. Sorry if this was already said.
Edit: So the conclusion people came to is that the plane will take off because it will start to move forward because no coveyor belt will ever be able to keep it static. Great. So why is the the belt in the puzzle and at what speed does it actually move?

Nope. Completely and utterly wrong on the bolded part.

The belt moves at the true groundspeed of the plane but in the opposite direction, and its purpose is to trick people who think aircraft are propelled by the wheels. -

Thx Akita I enabled images this time and edited my post. I still cannot belive the joke is so lame.

And i'm not saying otherwise either,just that in the case of Fighter jets,if the pilot chooses to do so,they're the only planes with engines powerful enough to make a vertical climb happen,and during that particular maneuver,wings are pretty much optional.
When a fighter squadron is on high alert status,standard procedure is to get those airplanes airborne ASAP,wich pilots hit the afterburners on their planes right on the runway to get to takeoff speed as fast as possible,then do the above maneuver(straight vertical climb)to get to combat altitude ASAP.

Translation, they operate in "rocket" mode rather than "airplane" mode Too bad they have like, what, 30 minutes of fuel tops (with a full tank) if even that much in that operating mode ?

Edited by: Baarhyn on 20/09/2008 05:16:04 funnay picture for j00
please, go to sleep guy it's ****ing useless :P
next time someone tell me the plane won't take off i'll add the magick vector and tell them that that vector make the plane take off because science says so and watch them ponder....

omfgbbq. some people in this world.... Grow a fricken brain stem. it can take off, it will take off, and it DID take off.
TREADMILLS DO NOT CREATE SIGNIFICANT LATERAL AIR MOVEMENT TO HALT THE UPWARD PROGRESS OF A PLANE!!!! ZE ENGINE IS ON AND RUNNING!!! THE WHEELS ARE INDEPENDENT!!!! GAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Originally by: digitalwanderer Fighter jets.....There is a difference.
They're the only planes where the thrust output of the engines,when running at maximum power,is actually higher than the total weight of the plane itself,hence they can climb completely vertical should the pilot choose to do so.....Wings in that situation are completely useless for their actual lift properties.
Just for completeness sake, I THINK there are propeller machines that can do that. You know, those things they use for aerobatics, how are those called? Aerobatics planes?
Anyways, some of the stronger ones should be able to climb just using the propeller. I dont know how reliable that is (its been a while, im not THAT up to date, the last data i got must be about 15 years old) and if the engine would overheat very quickly, but meh.
I'm sure you seen them "hanging" in the air, using the plane like a helicopter, tho. same shitz, just without gaining height
