Runways not needed for take off.

[waggy]

OP you are such an asshole! :twisted:

Mythbusters have already proven a plane can take off from a treadmill. Whether it would be cost effective though I find doubtfull. Maybe for aircraft carriers.

no. Aircraft carriers already have a good system in place.

Won't work.

EDIT: I thought windmill in op's graphic was a fan in front of the treadmill. Realize now it was just a distant power source.

Fan will generate lift.
Fan will not generate thrust.
Treadmill does nothing.

I suppose, if the fan were tall enough and powerful enough, and as mentioned, eliminate the vortex, and you could keep the plane level, you could power up and fly out of the airstream.

I like this, very easy to understand.

OP seems to not know that it isn't the wheels that drive the plane forward on the ground but the engines. it would still moved forward even it the treadmill could go 200 mph.

besides didn't mythbusters already take care of this?

Mythbusters experiment was kind of weak and not sure it can be used as proof.

BUT I still think plane will take off.

The only thing i see as being as issue is the wheel bearing taking double/triple the speed/stress of a regular take off.

How would it land?

If planes have elevators how come they always make you take the stairs?

I'm surprised that so many people come in to argue this topic time after time.

WOA, you have NO understanding of the issue. LOL

Cost effective?

The plane takes off because it moves forward. All the treadmill does is spin the wheels faster....

Or, if the plane had really good brakes and tires. Slam on the brakes = instant takeoff! :hmm:

According to the OP's diagram, if the plane applies the brakes hard, the plane is going to be catapulted BACKWARD. Can a plane take off backward?

 

[who?]

The book about the Air America airline says that the stall speed of their Pilatus Porter airplanes was 35 mph. If they were on a mountain top and the wind went faster than that they could take off from the wind generated lift.

You know how I know you weren't really paying attention to that episode?

I was kinda hoping OP would be about EM catapults or giant slingshots or something. Troll Physics is so fucking 2010/11.

Don't the wings have to have air rushing over them in order to generate lift from underneath the wings? I don't see how moving the wheels going 200 m/hr would generate the air movement over the wings to generate enough lift for the airplane to actually fly.

 

[M0oG0oGaiPan]

dyel? you've never worked out at one of those crappy planet fitness gyms have you? they usually have a sea of treadmills and some how those things break down constantly. takes forever to get up and running again.

DING DING DING YOU WIN!

Well its actaully the low air presure on top of the wing the generates lift

I'm surprised how often it gets posted. I thought it was a necro at first, same arguments, different thread.

Have the tipping threads taught us nothing?!

 

[exdeath]

A treadmill won't work, but a giant fan would.

 

[Krazy4Real]

The plane takes off.... it always takes off.

 

[Kev]

Wouldn't the treadmill in this be completely pointless anyway?

Not for a fat pilot who needs to lose some weight so the airplane wouldn't need as much lift to take off.

OMG, I hope you stole it from somewhere and didn't actually make it yourself. I cant believe that you are so retarded...
