will it take off?

[JoeL4330]

You don't need a treadmill on an aircraft carrier (it won't help.) What you need is a way faster aircraft carrier to reduce the relative landing speed and proportionately reduce the landing roll.

If a carrier could go as fast as the landing speed of the plane then the plane would make a vertical landing and not need arresting gear. Every kt of speed the ship makes good is a kt of airspeed for the plane and a reduction in takeoff roll and landing speed.

Any design ideas for a hydrofoil carrier or a hover craft carrier?

If the carrier went that fast, the problem would be to keep the planes on the deck (how about "arresting gear"?) ...In fact, there is a design for a 70 kt AC, not to blow wind across the deck but to get to the trouble spot quicker ...and, the problem such a design raises is keeping anything on the deck ...like crew.

I may be way behind the times in terms of speeds of surface ships, but doesn't a fast Destroyer move at about 50 kt, if that? What kind of hull design would enable a ship as big as a modern carrier to move at 70kt? What kind of propulsion system, presuming nuclear power to run the props or enclosed screws or whatever would make the thing move that fast? Wouldn't cavitation get to be a serious problem in anything but glass smooth seas?

I've seen pictures my uncle took of a freighter in the north Atlantic with both ends sticking out of a wave during a storm. What would happen to the drive train if a rapidly spinning prop was suddenly free of the water?

Granted, the skipper should know better than to run fast in rough seas, but one has to wonder about the final drive overrevving.

I haven't read all of these posts, just several hundred of them, but it encouraged me to make a little experiment. I don't know if it matters whether it is a prop plane or a jet but I used a jet for my experiment.
I connected model airplane wheels to a large skyrocket. I set it on top of my high speed beltsander. I put 2 screweyes in top of the skyrocket and put a little round stick through the screweyes and stuck it in a hole in a 4x4 that was behind the beltsander so that the jet could not go backwards or sidewards, just straight until it came off the stick. Then I lit the fuse and turned on the sander. It just sat there with the wheels spinning like mad until the rocket lit. When the rocket lit, it took off like, well, like a rocket! The sander didn't even slow it down a bit. Just missed my neighbor who was out mowing the lawn. Explained everything to my neighbor and she accused me of drinking too much. The wheels were pretty worn down from the sandpaper. If I ever do it again I think I will use finer sandpaper. Also, I will make sure my neighbor is not at home. Not a very technical experiment but maybe if my grandson ever needs a science project for school......hmmmm.

ROFLMAO.... I wish I coulda seen the neighbors face.... That's quite the "experiment."

Hahahahahahaaaa!!!!!

AHEM!

I'd just like to point out that somewhere back around post number 600 give or take 50 or so, I predicted this thread would last to at least 750 posts. We have now done that, thank you very much.

It's here! They are doing it on Jan 30 and Jan 31. Should be interesting.

Not that interesting if you already KNOW what the answer is.

Re: Mythbusters/airplane/treadmill

I enjoy watching the show and always learn something from it. I can usually think of a scenerio that they didn't look into or try, but most of the time, they are way ahead of me. There knowledge and skill level is exceptional.

I'm at a loss to the reason for your post or the link? Is there something special about that episode? Why link to the TV Listings for the show?

Yeah, when I heard that at the end of last night's Mythbusters show I thought "Hey, cool - they've been reading TBN!" I wonder if they'll give TBNers credit(?).
