And here comes Tim the “tool man” Taylor!!

[Tennessee_Bob]

Great, so much for the border fence! The Mexicans will be flying across!.........

That's why I'm getting ready to market the Patriot's Home Stinger Kit!

[ReignOfError]

You first.

I’ll be watching.

Hold my beer.

Vic Morrow came into our mess hall one day in VN and
sat down with us.Seemed like a great guy,I talked of how
I enjoyed his Combat show

Some of the grunts around another table asked him if
he`d like to go out on patrol.He said he thought he was
getting to old

I hated hearing about that terrible accident

"IT'S THE YEAR 2008. THERE WERE SUPPOSED TO BE FLYING CARS. I DON'T SEE ANY FLYING CARS. WHY. WHY. WHY?"

There was a glitch in the developement of the flux capacitor.

[Hoof Hearted]

"Decapitation waiting to happen."

Yeah, I'm sure the designers never thought of that.(sarc/off)

He joined the Navy in 1946.

The movie incident was more sordid than I remembered.

The vane would create yaw force from the downward relative wind created by the main rotor. The vane looks to rotate about the horizontal shaft. So, if the pilot rolls the yaw vane to the left (top edge left, bottom edge right), the force of the air pushed down from the rotor would create a yaw to the right (facing right movement). Ditto for left yaw input

Thanks. Two questions, and please forgive my practical ignorance on this:

Is the yaw input sufficient to keep the helicopter from spinning altogether? If so, why do most helicopters have tail rotors or, in the case of big ones, counter rotating sets of blades? Wouldn't it always be easier to use the little vane?

Seems to me that vane would just cause an otherwise unspinning system to go left or right a little. Newtons law says that if you spin a rotor one way, the rest of your system will spin the other way with an equal force (equal and opposite blah blah). So, unless the little vane captured all the energy from the main rotor, it would not impart enough force in the opposite direction to keep the helicopter body from spinning, because more force would be going into the main rotor than would be returned by the little vane.

Be that as it may. What difference does it make, spinning-of-the-body-wise, that the rotors have jets on the end, which seems to be the main point of the article?

Anyway, it's clear to me I am missing something on the physics of this system in a fundamental way.

Did not know it was that bad a story

Thanks for the link

Strapping on looks like the easy part...

Only if you're a woman.

For us guys, the straps cut into the family jewels. Big time!

Oh, and by the way, the girl in the picture is jumping "Hollywood".

Try it with a full combat load!

[airborne]

Oops! I meant “woman”. Not girl.

My humblest apologies!

Mad man.

So then how do you say tire in spanish ?

This was invented some 50 years ago in the form of the Hiller Flying Platform. A local fellow owns one, and it does fly.

[commonguymd]

Reach for the sky! Whoops..... Didn’t needs those hands anyway.

[chainsaw]

Don’t laugh. I remember the guy that pilots reported at ten thousand feet sitting in a lawn chair suspended from a bunches of balloons filled with helium, and a altitude control device - a BB gun.
