will it take off?

Ohhh Gawd...This thread has come alivvvvvve again! Someone just shoot me!!!!

I couldn't decide to whether to laugh or cry when I saw this. But what better place to have my 800th post, as this one is it. I would love to fly in a plane that breaks the sound barrier... how cool would that be?

The way this thread's been going and going and going then gone and going again you could very well post your 1,000th post.

That used to be possible but not now. The Concorde used to come to Oshkosh and they would load people up, head north over Canada and get her above Mach 1 for a while. While I would have loved to have ridden on that plane, it was too expensive for me. They say you can't tell when it happens anyway. What a rush it would be to fly that thing at about Mach 2 at <500' agl. I don't know if it would go that fast down low, but whatever full-tilt is, would do.

At Mach II and 500 Feet above ground level... push when you should have pulled and its all over quicker than you can blink!

I had forgotten about the Concorde.... That would have sold my issues, but I think that's outta my budget for this project.

 

[Jimbrown]

This ain't mach 2 but I bet you would think it was if you were in it.

OH MY!

If a plane is flying upside down over a runway that is going in the opposite direction at the same speed, what happens to the two guys holding the sticks?

A third guy pole vaults?

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?

Alternatively you can install big fans to blow lots of air down the flight deck. This is as effective as having the ship go faster. If there is enough wind down the deck the aircraft can land vertically or nearly so.

This is easy to test with say a T-Craft. A Taylor craft has such a minimal landing and liftoff speed that in a stiff wind you can essentially make vertical takeoff and landings.

Landing backwards under highwind conditions has also been done. I don't recall what happened after it was down though. I don't see how it could have remained on the ground other than as a crumpled up ball.

Harry, So far I have never landed backwards but a buddy with a T-Craft has. He had to rev up to hold his ground and needed assistance to get him tied down as the T-craft had no brakes.

I have made some incredibly short takeoffs and landings at Bull Head City, Arizona when the wind was blowing like crazy right down the runway. The hard part was the taxi from or to the runway. Any more wind and I'd have had to have people hold down the wing tips to taxi.

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.

 

[daTeacha]

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?

Re: Mythbusters/airplane/treadmill

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(?).
