Title: Boomerang
Post by: Mike Griffin on October 23, 2015, 11:54:04 AM
One of our club members, Bob McKinney, was a great Carrier flyer back in the day and today he makes some of the best flying boomerangs available.  He hand makes everyone of these.  Today we took a break from our work party at the field to fly some oh his creations.  These things are a ball but really hard to stunt....every Aborigine in the park was jealous this morning.  We probably will have to get a permit and register these things in the future...I mean the crooks gotta get their cut....

Glenn the Axes look really neat flying through the air and fly just like a regular looking boomerang.

FWIW.... I know what an Australian calls a boomerang that won't come back.

A real hunting boomerang doesn't come back. You pick it up right next to the dead critter that it just clonked on the noggin. They have a lot less "sweep" and are thicker. The one I have appears to be made from "ironwood".  H^^ Steve

You see one about a meter across , 40 odd inch , in old money - and question if a head would be the right place to catch it .
Theyll break a arm or leg , or stop a Kangaroo . Which takes a bit of doing .

The Airfoils got high center of pressure and center of lift capeability , high subsonic .
Descibed as the most mechnically simple aerodynamically sophisticated contrivance of mankind .

There was a British  society for the promotion and avoidance of boomerangs . LL~

Should be a thumb notch and lanched forearm near vertical between thumb and first finger , and itll do all the work , if its a true stone groound bush boomerang .

A Woomera ( spear thrower ) and rock would be a match for a F 14 at 100 ft , head on . With those Intakes . Theyll toss a spear 150 yards .

Were quite a few natives in the ANZACS , and a  fighter pilot .   (http://www.anzacwebsites.com/tradition/aboriginals/len-waters.jpg) Len Waters .The foot sloggers in the N.T. wouldntve survived without their guides .

Thanks for the video.  Have never seen one in flight.  Might be great for getting the arm ready for the Fox engine hurl. LL~ LL~

A friend of mine owns one of the 2 remaining airworthy ones. I asked him what it's like to fly. Answer: "Bloody horrible!"

Dunno how close the CAC Boomerang is to this NA 50 / NA 64 , but similar , Wirraway Derived - which is a Harvard Derivative .

Getting back to the original intent of this post,  these are beautifully crafted flying objects and with a little practice you can catch them as they return.

  I got mine to return just fine, but I declined to catch them after I saw the sort of divot they dug when they hit the ground.

Isn't it amazing that MTA (Maximum Time Aloft) boomerang world record flight is about 4 minutes long? You have to throw & catch it inside a 100m diameter circle. I've managed about a minute, more than 10 years ago. L
