plane on a conveyor belt?

[Golfer]

Kurt, FWIW the story I have for that video is:

Left hand cuff of his flight suit caught the nozzle lever while manipulating the power lever.  Loses the downward nozzle for vertical flight...no airspeed for conventional flight.  Supposedly he also broke his leg when he landed on top of the airplane after punching out (doh!)

Just think about the effort you made on the kid.  I'm sure that "14" in his handle stands for something...

I dont beleive that if JB88 drops an 85 pound rock on his bare foot that it will hurt.

I wanna see the proof!

sorry, but there is no way that you can convince me that drediock only weighs 85 pounds.

Kurt,

You seem like a knowledgeable and intelligent guy. If you will notice at the top of this page I commented to him it may have been a hover flight problem. He responded apologeticaly showing me that he hadn't thought of that aspect of it. True, he did jump to conclusions, a lot of us do, and appears to be a youngster that doesn't have our life experience so he made a statement on an incorrect assumption.

I don't think being harsh with him about it does much good. Perhaps an explanation would have been better?

sweet thread!

It makes me wonder why a plane taking off against the rotation of the earth wouldn't have a tougher time than a plane taking off with the rotation of the earth. I'm sure airspeed has nothing to do with it.

I do have to take exception to Hitech's explanation. If there were a belt capable of rapid acceleration to counter the tire's rotation, it would rely on some sort of friction that would inevitably react with the air. This would create a mass of air turbulence that would actually launch the plan faster and before reaching anywhere near infinity. Of course, if the tire were only exposed on the bottom to this magical wonder belt and nowhere else, this effect would be reduced, though the effect of spinning this magical belt at near infinite speeds would most certainly cause it to expand in diameter effectively launching the plane straight up anyways.

So many effects... so little consideration. Tsk tsk tsk.

Random thoughts.....

Have you ever seen an upside down triangle on its side?

Have you ever heard the sound of one hand clapping?

Funny.  I actually considered the conveyor's effect on the air around it, but I figured the airflow would be too turbulent to create lift.

Actually, that's a decent thought Majic.  I bet he could take off at 90% regular velocity because of the boundary layer on the conveyor belt.

if their was a treadmill thingy capible of speeding up instantly can u beat it with of of those half plane half helicopter things (i think their called Tilt-Rotors)
points the engine forward to force forward put tilt the engines to the blades r above the plane and create up lift

this is what im talking about

and i heard these things are more unstable in vertical flight then harriers

and Kurt i apologised, isnt that enough?

[lukster]

A really fast moving conveyor belt would create a low pressure area near it's surface would it not?

[Wes14]

i thought with that thing spinning that fast it would force a small bit of air aganst the plane itself?

I saw his post, responded, I didn't see yours or the response till later, so, yeah, I flew off the handle.

But - Regardless, I don't feel to bad about coming down the way I did.  By 14, I understood the difference between a trained pilot and my 14 year old vision... And my daughter at 12 already understands the difference between someone who is trained to do what they do, and herself...

So, its double edged I admit... Had I read the following posts before responding I wouldn't have reacted as I did.

So, this, is not exactly an apology, because I'm not wrong to sternly correct a dangerously misguided opinion... But it is a retraction of the attitude based on facts that came to my attention afterwards.

Perhaps we both learned a lesson.

yep:aok

acually im thinking of being a bomber pilot when i grow up:D

any suggestions?

You are in the company of all sorts of pilots here...  I'm sure one has that answer.  Sadly, its not me.

What I do know is that you'll do well to get a strong background in mathematics, and as you go forward to college, be thinking about schools that can teach you aerodynamics, aerospace engineering and such.

[Wes14]

thanks:aok

i think it would be cool to be assigned this plane

 

[Kurt]

Well, if you are 14 as everyone is guessing, its likely there won't be any active A-10's when you are flying.  The Air Force has been trying to deactivate them for 15 years.

I'll never understand why though, it is the perfect design for the role.
