I'm sitting here contemplating the fuel temp thing...
and wondering...
Does the plane take off?
Only if it refuels in the morning. [coffee]
No, Because of the GFC, the Plane's owner went broke and now it's sits on the Tarmac, unused and unloved.
Awaiting it's trip to the Plane grave yard.
oh no!
[popcorn]
Only if the little kid unties it.
I'm going to forget I opened/saw this thread.

On a similar note, but different question: I received this in an e-mail today. I believe that it is rubbish and will state my case as to why later. In the mean time for you to ponder...
[popcorn]
"A Factoid that I learned in A300 FAM class is that any tire, regardless of tread, will hydroplane at a MPH speed of 10 times the square root of the tire pressure.
My SUV has 36 PSI tires, so it hydroplanes at 10x6 = 60 MPH.
Useful to know, because you cannot always "feel" hydroplaning."
How long until this gets merged into TOSAT?

Um, why does your tire have roots? And aren't roots round? [drink]

Are you in competition with Mr Exact?
What about a 2000 pound car versus a 4000 pound car running the same tires? Regardless of tread? So a bald tire won't hydro plane any quicker than a brand new one? What about slicks vs rains? ill just air up my tires to 50psi and never have a worry.

No. I didn't see him posting yet tonight, so I thought I might just post some random bullshit, meaningless opinions or opposing viewpoints in his place.

at what altitude?
and time of year?
ambient temp?
airbus or boeing?
need more data...
If it looks like this plane, it will take off
F35 JSF take off. (http://www.youtube.com/watch?v=Xm7_PPE-8nk#normal)
I'm thinking the hydroplaning issue would really be complicated by airplanes taxiing on a rain-soaked treadmill. Seriously, what kind of pressures would they have to be running? Or are the tires solid rubber?

Quote from: Randimus Maximus on October 15, 2009, 06:55:50 PM

wouldn't those never hydroplane? If they are solid then the pressure is infinite right? or is it the other way round - the pressures zero... So they are always and forever in a state of hydroplane...
And the plane takes off when it flaps it's wings... Duh

1. Many aircraft tires run something like 27 plys. [Not exact]
2. The air temps at altitude drop down to around - 40 So there are fuel heaters just before the fuel metering devices to heat up the fuel.
3. I wouldn't worry much about hydroplaning on the runway since the plane is being steered by the flight control surfaces anyway.
4. Giving one dog a rib bone with lots of fat on it, and no bone to the other dog can be somewhat entertaining. But if you give bacon to one and the other ones sees you do this, then you have to give bacon to both dogs. And some to yourself...
Mmm, the bacon paradox.
Glad you brought that up

Thats barely an airplane, its more like an ultralight. How bout this one? Can a plane land on a treadmill?

an airplane can "land" on anything.
some landings are just softer than others
Take offs are optional, landings are mandatory. Unless your tires are hydroplaning or you fueled up before 6am.

won't sail upwind.

Can you ride a Duc on a treadmill? [popcorn]
kind of like putting it on the dyno..
based on exhaustive scale model research, the size of the Duck makes no difference...they cannot take off from a treadmill.

Actually,hydroplaning can cause quite bad problems with blistering tires on a large aircraft. It makes it more likely that the tire will skid under braking. Of course Anti-skid systems alleviate that when functioning properly.
I say it is BS, because if not I am going to go out to the parking lot in the rain, let the air out of the tires of a Corvette (run flat tires), then push it anywhere I please. If the formula is correct, the hydroplaning car at 0 mph should be easy to push. You could have a lot of fun at a chevy dealership rearranging all the corvettes...
The equation is based upon gas laws and pressures, but ignores the structural characteristics of the tire.
so what happens if the tire is over- or under-inflated?
It doesn't take off
Dp's right.
In fact, the tire actually goes back in time.

So it becomes a bias-ply tire?
and yes, I realize that some of you whipper-snappers have no idea what I am talking about
Well, I can tell you that from the famous Schrodinger's Tire experiment, where tires are mounted to a bike with a rider and placed into the box, we learn the bike is leaning left AND right.
AT TEH SAME TIME!
That's trippy, ML!

Ah, the good ol' pizza cutters.
Negotiating a turn is a 3 step process.
1: Turn steering wheel early in anticipation of car changing direction
2: Tire flexes and then settles in
3: Car finally turns
my first vehicle (used toyota fj40) came with bias ply tires. big old military tires.
driving on ice was amusing...
What about the damn plane?
Your seat becomes a flotation device when it crashes into the water.

It still has infinite width and length, zero thickness, and zero curvature.

I told him not to park it on the conveyor belt.
It will take off because it is not being propelled by the wheels but by the prop. the speed of the wheels have no effect.
