The Boomerang

A boomerang is a flying object with at least two blades, with mullions. Launched by hand to rotate on itself, it flies in a curved path and can return to its thrower. The lift developed by the rotating blades partly determines the characteristics of its trajectory.

The term "boomerang" is general given to a flying object that goes back to its starting point.

Method:

1.Locate wind direction and stand in front of it. The launch takes place at an angle of 45 ° with respect to the wind.
2.Hold the boomerang so that arms are horizontally in front and perpendicular to the ground.
3.Bring arm behind your head, then throw the boomerang in seeking a trajectory parallel to the ground, while giving it a rotation on itself.
4.Analyze the return path:
     a)The boomerang returns directly into the hands: bravo!
    b)If the boomerang falls before the launcher, restart in a direction that forms a more acute angle with the direction of the wind.
   c)If the boomerang falls behind the launcher, restart in a direction which is more open with the wind angle.

The sport of boomerang has been a source of competitions around the world, with different types of tests. According to them, the classification is based on the path length, accuracy, duration, speed, or imposed catching. There has been a World Cup since 1988 in different countries and an international federation manages the settlement of tests and certification records.

Each event has its often very specific boomerang to reach more easily the objectives of the test.
Speed: This is to catch the boomerang five times in a short time
Endurance: You must catch the boomerang as many times in the space of 5 minutes .

This is to die for (not catching) the boomerang closer to the center of the target from which it is launched 
The M.T.A. (Maximum Time in Air): This is the boomerang to throw as far away as possible. A rather typed boomerang is used with a blade longer than the other, and very light.
Distance: It is sending the boomerang as far as possible . Consecutive shots (or collisions): It is to run (and catch) the boomerang as many times as possible.
The Freestyle (or Free-style): This is to make figures catching the boomerang.
The Aussie-Round: Complete edition combines a test of distance, accuracy and retrofits.
The boomerang must travel a minimum distance of 20 m from the place of launch.

The boomerang is one of the main objects of the Legend of Zelda series.

A four-bladed boomerang, the cross (holy cross) is a recoverable secondary weapon in Castlevania series.
The boomerang is available in many forms as the main weapon in the gamecube game: Ty the Tasmanian Tiger.
The boomerang is a throwing weapon of the Egyptian civilization..
The boomerang is the weapon of choice of the character Hope in Final Fantasy XIII. It can decapitate a series of online opponent and return to the left.

Industrial manufacturing focuses on laminated wood or plastic. It is possible to make boomerangs in many materials: wood, plastic, bakelite, fiberglass, carbon, etc..
A pattern of cutting a sheet of dense plywood, preferably with a lot of layers (marine grade gasoline moabi mahogany, birch or aircraft-type), woodworking tools and a few hours are enough to get a model for beginners. We can cut the profile to the grater and finish with sandpaper, regularly trying to work till satisfaction.

A boomerang has a curved path, and is constructed such that it issued back to its starting point.
