Kylie / non-returning boomerang - training & experiment

[2011-07-13]

Non returning boomerang made from a tree branch with two crotches.

I added a weight (natural iron ore + leather + cotton thread) to see whether it would stabilize the flight. This shifted the center of mass off the boomerang. It probably also increased the drag toward the earth. The global increase in mass would allow the boomerang to have more kinetic energy for its forward movement. All this seemed to flatten the trajectory (in this case) without diminishing the flying distance too much. But it not so clear, as it depends so heavily on the way you throw the boomerang.

(Admire the fabulous artificial antelope !).

I'de tie a fish line onto it. Pretty cool

@supergooddeal

Thanks,

a fish line ? or a fishing sinker ?

I tried with a piece of lead (with another non-returning) advised by user "pucikam" : not so obvious to get a long flat straight flight. But actually, my aim would be to make a "perfect" non-returning boomerang only by means available in a primitive culture.

Great looking stick at any rate. Seems real hard to get on target, though. How is the range compared to a rabbit stick? (non airfoil throwing club)

Also, I love the target "animal" but it needs giant googly eyes.

@Chugosh

thanks,

yes, it's hard (for me) to hit the target ; more training would help, and also a better profile (for more stability) ; useful range = ~25 meters for this particular stick ; but it flies to 50 meters ; (didn't try any rabbit stick yet) ;

Pretty cool.

What was the purpose of the modification you made?

What sort of game do you think this would be able to take down?

@ROBwithaB

thanks ; I was trying to get flatter flights. The holy grail : straight flat flights over long distances (~100 m). Instead, you may obtain curved or soaring flights, or diving trajectories, or a light boomerang that doesn't go very far. Some of the behaviours of a problematic shape may be corrected by adding weight, or shifting the center of mass, or increasing the drag (downwards or upward) somewhere. [I don't hunt for real ; this kylie is "dangerous", even for humans].

@freejutube LOL no what I meant was tie a fish line to it so you can pull it back to you after throwing. Just kidding of course. I think your throw is really good. The kylie your throwing has a nice smooth flight. Balance of the Kylie is very key. Seems as though yours might have to much weight at one end due to the extra material and shapes. Practice, practice. You'll get it.
