Boomerang Terms

Boomerang Terms and definitions 

Airfoil  - this is simply the shape given to a wing which has a leading and trailing edge. 

Angle of attack  - This is the twisting of the boomerang arms which will have either a positive or negative effect on the boomerangs flight depending on the upward or downward twisting of the leading edge.

Angle to the Wind  - this is the direction of your throw relative to the wind.  A good angle to the wind is between 45º to 90º to the right or left of the wind depending on which hand you throw with. 

Positive angle of attack  - this results when you twist the boomerangs arm so that the leading edge tilts upward.  This will typically reduce the range of your boomerang

Boomerang  - Webster defines this as a bent or angular club that can be so thrown as to return near the starting point.

Boomerang Template  - This is a template of a boomerang usually made out of 3/4" plywood.  This template is used to trace your boomerang onto your plywood and to use a guide for your router to follow when you are cutting out your boomerang blanks.

Dihedral  - is the upward or downward bending of a boomerangs wing.  This is a technique used in tuning. 

Dingle Arm  - this is the arm that has the trailing edge on the outside of the dual blade boomerang. This arm controls accuracy. 

Dual Blade Boomerang  - this is a boomerang with two arms.

Elbow  - this is the point where the dingle arm and leading arm meet. 

Forefinger Grip  - This is the act of gripping your boomerang by placing it in the palm of your hand and wrapping your thumb, pointer finger and forefinger around your boomerang.

Height of Throw  - This is how high above the horizon you should throw your boomerang.  Typically 10º to 20º above the horizon is ideal. 

Leading arm  - this is the arm with the leading edge on the outside of the dual blade boomerang.  This arm controls range. 

Leading Edge  - this is the front edge (typically more blunt than the trailing edge) which leads the boomerang into the wind. 

Negative angle of attack  - this results when you twist the boomerangs arm so that the leading edge tilts downward.  This will typically increase the boomerangs range.

Negative Dihedral  - this is the downward bending of a boomerangs wing tip.  This will decrease lift to the boomerang and cause it to fly lower.

Pinch Grip  - This is the act of gripping your boomerang by pinching the boomerang between your thumb and pointer finger. 


Positive Dihedral  - is the upward bending of a boomerangs wing tip.  This will add lift to the boomerang which will cause it to fly higher. 

Tilt Angle  - this is the lay over at which you throw your boomerang.  Typically this is between 60º to 90º 

Trailing Edge  - this is the rear edge (typically more slanted) that trails behind the leading edge. 

Tri Blade Boomerang  - this is a boomerang with three arms. 

Tuning  - This is the bending or twisting of the boomerang arms which will result in different flight patterns. 

Undercut  - this is an area where the material has been removed from the underside of the boomerang either on the leading or trailing edge.  Typically this is done on the leading edge from the tip to the elbow not exceeding more than two inches.
