Hi nice post, i have come across your site once before when searching for something so i was just wondering something. I love your theme, would it happen to be a free one i can download, or is it a custom one you had made? In a few weeks i will be launching my own site, i'm not great with designs but i really like the style of your site so it would be cool if i could find (or pay for) something with a similar look. Thanks!

I am using all this informtionand debating for a prject of mine. You all have such valid points (maybe except for Royce) But i beg of you to thank Gary M. Broadbent,he is a true genius. So thankyou. Iyou have been very helpful and this information will be an excellence addition.
Thankyou all.

i think it will fly like a poo

The boomerang being thrown on the ISS is a roomerang which I designed!!!! It is not paper it is .020 polystyrene. It was thrown in the space Shuttle on flight 51 in 1993. It comes back just fine, right back to the thrower in almost zero G. The boomerang can be tuned to fly in any condition. You can contact me with any questions you might have regarding the behavior in space.
I hold 4 world records on the USA Boomerang team, and own the worlds largest boomerang collection at over 15,000. Gary M Broadbent Canton, Ohio

This doesn't seem so complicated. It's flight will be curved in a direction normal to its rotation. 90 degrees from the plane of it's level flight on Earth. It will sort of look as if it rising like a helicopter. It will still curve in its typical direction as well.

Think of a helicopter. The boomerang and helicopter operate on the same principles. Except that the helicopter also has a small secondary rotor on its tail to counteract the torque that makes the boomerang go around in a circle, since it is generally considered a bad idea to have a helicopter that just flies around in circles.

I do think that without gravity, the boomerang will have to be even more carefully balanced and thrown to avoid tumbling, since gravity, acting equally on all parts of the boomerang, tends to stabilize it a little.

Air resistance would still be a factor as there is an atmosphere on the space station (luckily for the crew).
Could think of this all day.

Hmm 327th Male, now I'm wondering about the exact flight characteristics of a boomerang without gravity. I still say the thrower will be at the center of the flight path because there wouldn't be a "catcher" with no gravity to counteract the lift. But – would the flight pattern be circular, eliptical or even a figure "8"?

Kathy, they had that TV show long ago about trying to get back to earth with spare junk. It was called Lost In Space, lol.

This experiment does have a potentially practical application if you are wanting to design the best shape for a wing using solar wind as its energy source. But, it does seem logical to just use computer modeling. In the end, it is a mathematical problem.

One way to make sure the boomerang would come back would be to go outside the Space Station and throw it with enough velocity to put it into orbit around the Earth….Oh wait, it already is in orbit, well still, throw it hard enough to make it fly around the Earth and catch up with the Station, perhaps hitting someone in the back of the head.
Now, how about testing to see if a yo-yo works in zero gravity? This would give new meaning to the "around the world" stunt.
Or what about testing a hula-hoop? This would not only pay-off with an abundance of scientific data, but would help keep the researcher-astronauts in shape, and happily occupied. Nice way to lose that touch of flabbiness around the midsection…
Actually, how about a frisbee-catching dog experiment? You know, throw the frisbee and the dog chases it and leaps up to catch it in its mouth. Then, in zero gravity, the dog just keeps flying through space and crashes into the wall of the Space Station, much to the amusement of everybody. I'm not sure what the scientific purpose would be, but it would still be funny, at least for the sadists on board.
Actually, how about engineering a line of jet propelled skateboards, and you could have a three dimensional skateboard track looping around inside of something like a spherical room?…But then, why stay inside?…The astronauts could "jetboard" around the outside of the Station, or on the exterior of the Space Shuttle — you know, a little visual excitement to get the kids involved in the Space Program..Eventually we could have a spaced-out version of the X-Games — on the Moon — using giant craters for jetboard runs, and you could do cool tricks, like jumping from one crater to another, flying for hundreds or thousands of feet at a time. The finale would be a race where the contestants gain enough speed to leap out of a crater and put themselves in orbit — the first contestant around the Moon wins. The trick would be to be able to launch at a speed and trajectory that doesn't overwhelm the moon's gravity and send you flying out into space. For those who do fly away, there could be high-speed tracker vehicles to (hopefully) catch the wayward contestants –using giant nets. In fact, this could be another contest to see who can net the most jetboarders. It would sort of like roping baby steers at a rodeo, only on a grander scale….Or how about a televised science series, where contestants are placed on the Moon with giant piles of discarded materials from rocket construction sites, and barrels of various chemicals, oxygen and water supplies, computers, used space suits, and whatever, who knows, and a supply of high-tech tools — and the contest would be to see who can get back to the Earth first, using the materials on hand.
Oh the possibilities! Please someone… give me some funding!

You might be right about the lift johnny, I hadn't thought of that. I doubt the thrower would be at the centre though – they'd be at the edge of the first circle.

My vote: given enough space (currently not available in the ISS) to fly within an air filled enclosure, lift would cause the boomerang to keep rising upwards in wider circles as air resistance slows down the rotation. The boomerang would end up high above and far away from the thrower, stopped dead in its continously widening arc. And, given a proper send off, the thrower will remain at the center of each widening spiral upwards.

Here you are Rev perhaps this is truth?

http://www.boomerang.org.au/articles/article-how-to-throw-a-boomerang.html

If you have the option, avoid throwing in anything over moderate wind. Some boomerangs need a small amount of wind to return completely, but most do not. Rain generally has little effect on boomerangs in flight, but ensure any such boomerang has been sealed against moisture, and remember to dry your hand and the boomerang before each throw, to maintain your grip. And at the other end of the scale, donâ€™t forget the sunscreen!

Guess it final… inhabitants of the ISS will be playing "boomarang" along with ther "ping pong" activities.

Bet you could just ask any of the aborigines' tribal leaders in Australia, and they'd give you the answer.

When an Australian boomerang is thrown it is aimed vertically, slightly upwards and 45 degrees off the wind. By the time it is horizontal it is in the direct line of the wind to the thrower. As it loses lift it is returned by the following wind. So, you do need a wind. A wind less than 5 kms per hour. That is my observation. No wind no return?

Methinks they'll need to build a bigger space station to test this one properly.

Hmmm. My prediction, assuming ample space, is that the boomerang will fly in a circle. Wind resistance will slow its spin, causing the circle to get wider and wider, eventually flying off in a straight line.

Yes it is being thrown inside the station. That is made clear at the bottom of the article.

What rationale are you using to predict that the boomerang should simply spin away?

By: Kevin

Kevin — Mon, 28 Jan 2008 20:01:31 +0000

Wind resistance? There is a breathable atmosphere on the Space Station just like here on earth, so that should be a mute point. No wind either, but that is also irrelevant.

Gravity is the question here.

i think that without wind resistance, which causses lift, and gravity, the outcome won't be anything like here on earth
