BOOMERANG

INTRODUCTION

A boomerang is an aerodynamically shaped object designed to fly smoothly through the air when thrown by hand and which follows a circular flight path that returns it to the thrower. Shapes vary from V-shaped to irregular shapes or with more than two arms.

Two design components are the essential features which gives boomerang the capability of circular flight. One is the arrangement of the arms, and the other is the airfoil profile shape that allows the arms into wings. During flight, the boomerang spins rapidly . The wing profiles in addition to it's spinning motion creates gyroscopic precession, which pulls the boomerang into a circular path.

To throw correctly,it should be held near the end of one wing with the top (curved) surface facing the thrower's body. The boomerang should be almost vertical, with the

The boomerang is thrown repeatedly to test its flight capabilities. Several types of adjustments may be made to tune the boomerang for better performance. For example, the wing profiles might be adjusted by additional sanding.

11. Another tuning technique is to bend the wings, raising their tips above the plane of the vertex which is for giving the boomerang a positive dihedral. It may be required to heat the boomerang to make it flexible enough for bending and to make the adjustment solid. This can be done with steam or even in a microwave oven.

12. Twisting the wings to raise or lower the leading edges can also affect the boomerang's performance.

13. Other tuning techniques are drilling holes into the wings, cutting slots in the leading edges of the wings, or drilling shallow holes into the underside of the wings and inserting lead or brass plugs to add weight.

The quality of the boomerang is periodically checked throughout. Any unevenness such as unequal sides or bumps will affect the aerodynamic design.

Boomerang innovations can be developed in two areas: materials and
