This had already been discussed.
If anyone else creates another thread about this, I will ban them!!!
ok since we have an actual engineer here i’m re-opening this thread because he wanted to add to it. PLEASE KEEP THIS ON TOPIC AND DON’T START BASHING EACHOTHER. if anyone goes down that route they will be banned. that is all 
ok i have seen alot and read alot of your ideas. Believe it or not. we have tried implementing these kinds of ideas for years. to be more efficient and make travel alot faster is our ultimate goal!.
a few of you have said , yes the plane will take off if the “treadmill” is running the opposite direction that the plane is trying to propel itself.
Reason number 1 why this would work in theory.
as some of you have stated, the wheels have nothing to do with its forward motion, if you said that you are correct, for this theory anyways.
CORRECTION! i erased what i wrote with the help of my supervisor he explained why this idea would not work. so i retract my previous statement!
ok i read a few other of your posts… i did not read this thread entirly… i saw the other one and read all 26 or so pages of that…
allow me to make a correction!
if the plane was on the conveyor belt and it was moving the opposite way the plane was traveling… and it was matching wheel speed! then no the plane would not take off.
it need the force of air going under and over the wing in order for it to create lift…
if the treadmill was going oposite as the plane then the plane would techincally not go anywhere on the runway it would be like its standing still… no wind speed/pressure passing under it, means no lift. so the turbines can suck up all the air they want. its simply not enough to make it fly on its own. it needs the force of the wind under it to create the lift…
my supervisor saw me and what i wrote and corrected me, asi now see the mistake i made
if the conveyor was going the same way with the plane then yes it will take off and reach speed faster then just a normal tarmac flight would.
the other idea i saw was that it would be easier for the plane to take off if the “treadmill” if it was going the same way as the plane.
we’ll use this as an example
ever been in an airport and you see the new escalor type deals that when your walking help speed your way to the terminal faster then not using it?
well in theory this idea will work here as well
reason why this would work…
think of your legs as the turbines
if you run on thattreadmill going forward the faster you can get of of it.
as opposed to standing on it.
the engine and turbines and full throttle as well as the forward motion would speed up this process by helping it along. and taking off faster.
which idea would work the best?
who honestly knows… this is all in theory and has never been tested by anyone yet.
although boeing is the leading, or one of , the leading companies when it comes to aerospace engineering, we would most likely be the first to try something like this .
the only thing that does not work in our favor is finding a way to set this up to test and the event of failure the amount of damage it could cause.
so you have brilliant ideas!
so do not let yourselves fall short if you said one answer instead of the other.
your ideas are geat and the fact that you guys and gals could think about this on your own and even come up with diagrams, which are awesome i might add, are simply amazing! i can tell alot of you have talent and are thinkers! which is more of what we need!
all the ideas and thoughts are correct in theory
whether this would work or not is yet to be seen.
there are also other ideas floating around alot of aerospace companies in which i cannot say too much about as of yet. due to confidentiality and trading secrets with other comanies rules and what not.
but i can say in thhe next 6 to 10 years look for plan travel times to get shorter and look for, well redesigned planes that are more aerodynamically correct!
if you have any questions feel free to ask!
thanks for your time you guys, i love your ideas!
also i forgot to add. if you are trying to implement these ideas… i do not think the standard of the current engines would work as well as redesigning them to work with these theories in the need that they go alo faster and wind up alot faster then they currently do now.
ahhhh not this thread…
but really, where were you like a month ago when people couldn’t fathom the reality of this
i was working to king car payments and trying to upgrade to a better place of living by not slacking off and being in the computer which i am on now talking to you guys. thats where i was one month ago.
Great. :roll2: You opened the thread for an actual real life engineer? Wow! Uh, you had engineers here before too and we tried to explain why the threadmill in reverse would not affect the forward motion of the plane, at least going by the setup of the theoretical riddle (the wheels were spinning freely, not oppsing any motion.) So sorry, but you and your supervisor are wrong based on the setup proposed. It would go forward, which does not need lift. It creates lift. Please relock this thread, even though we have a real life engineer here to give his incorrect comments. :banghead:
This deserves a rofl or ten. 
EDIT: What is with the forum breaking that one. So now it’s nine.
do i need to call my uncle who is an actual rocket scientist for nasa? Would that make everyone believe that the plane takes off because IT DOES!
Okay someone get me the following.
1- RC car with proportional controls
2- D or E sized Rocket for a model rocket
3- Old treadmill
4- Camcorder to record the R/C car smashing into a wall.
You need one of these:
The whole thing is about the same size as a Hot Dog… but way faster!
Ask zerodaze! He’s qualified to give the real answer because he works for a company that supplies treadmills!
/sarcasm
:lockd:
look, he pm’d me stating that he’d like to add to it…which was ironic because someone had earlier told me they wondered what his thoughts were on it. soooooo i re-opened it for discussion, on the grounds that you people could remain civil. so lose the sarcasm, k? thanks
wetwork,
The plane takes off. You’re a smart guy, think about it (without taking into consideratioin the bearings or wheel rubber compound). Think about it in terms of a small plane like a turbo prop. The plane takes off.
hahaha wait… look it is an engineer. Or did you not count in the beginning?
Will do. Sorry about that. I just got a little annoyed that he requested a thread to be reopened so he could add to it, then posted a looooooon thread with a little bit of incorrect content and a lot of what seemed like a lot of boasting about he works at boeing and he’s glad to see us young people blah blah blah. Then I guess I had my own arrogant prick moment and took it personal when I read “engineer.” But anyhow, my apologies.
Wetwork, think it over. Draw a free body diagram if it helps. Heck, work it out and bring it back to your supervisor and impress him! :tup:
Physics > a lot of people in this thread.
Stolen from OT:
Walter, I have a pair of rollerblades that haven’t been used in a while. Can I come and visit you, and we can play with my rollerblades and your bike?
Hell if this is still being discussed tonight I’ll simulate this using Half-life 2, and post a video of the results.
I have the perfect answer.
I can apply what a girl said in my psychology class to everything,
“I don’t think it will fly because God doesn’t want it to!”
PERFECT!
