actually… upon further thought… It probably would work. (as soon as I read about the drive system comment)… makes sense, but thats one hell of a trick question (unless ya really start to think about it)
you lived on a plane?
thats some serious jet set lifestyle.
you really are my hero
…anyway, verturi, bernoulli whatever, i took physics 10 years ago and i’m rusty. Figure 7.3: Lift of an aircraft wing
If there isn’t any air passing over and under the wing it WILL NOT move, i don’t give a shit about the wheels…ya know what let’s build a conveyor belt runway and rent a jet and then we’ll see…this is getting out of control, i need a beer.
that picture sucks so bad.
Easy example for anyone that can be tried at home. You will need the following
- Small/large die-cast car that can roll
- Piece of kite string
- Piece of paper
Step 1: Set car on top of paper
Step 2: Tie string to front of car
Step 3: Pull on string, while moving the paper back at the same speed the car is moving.
Step 4: Note how the car still is moving forward regardless of the speed the paper moves at.
EDIT: That picture does blow beefy chunk style.
I believe the engine would provide enough to overcome
the wings are there for lift ONLY and do NOTHING for forward motion. You can cut the wings off and the thrust will still accelerate the plane forward even if the conveyor is moving 10 X the speed of the plane. This is NOT a fucking car.
lets everyone reinvent the wheel
fucking engineering garbage
Plane takes off… end of story.
lift is not generated by angle of attack … but angle of attack can CHANGE the amount of lift by effecting the pressure ratio
only a flat wing would need to use AOA to generate any lift is if the wing is flat top & bottom …
and a NEGATIVE angle of attack would mean that the wing is nosing down into the wind … which doesnt create lift, it reduces it …
^ Correct
Much better pic. :tup:
where were you guys 6 pages ago? lol
watching the banter between people who dont know anything about planes
so that later i could jump in with information about thrust , prop hang (100% of lift coming from the prop, 0% frrom the wings) and all the rest of the needed info
because that has nothing to do with the problem…?
see, what makes this question so popular on car boards is we instinctively think automotively instead of aeronautically - the driving force isn’t related to the friction of wheels on pavement, but jet/prop propulsion on the air.
what makes this question so popular on car forums is a high content of dumbasses.
I think everyone is reading too much into this, in the original question it was stated that the conveyor would rotate equally opposite to the wheels, right? i understand that the wheels are free spinning and there is no force from the wheels moving the plane forward. This force would be coming from the engines. The engines, even if they could overcome the belt (theoretically speaking) could not move the plane fast enough to get lift. So IMO, the question, at face value, is a simple one. As soon as everyone started digging too deeply into it, there was just too much info in the answer to answer the actual question. An yes, i know my picture sucked ass.
If you don’t understand even after FuzzyFish illustrations you should kill yourself now.
Human race. <3
IMO, shuttup.
