Physics and mathematical model for boomerang flight

Abstract

The boomerang flight is presented in the known publications by the action of aerodynamic forces and gyroscopic precession torque. This solution does not give a true answer because gyroscopic effects are expressed by the action of the eight interrelated inertial torques generated by the rotating objects. The publications with numerical modeling do not describe the physics of the boomerang flight. Today, the solution of this problem is presented by the mathematical model with the action of the lift forces and inertial torques generated by the rotating boomerang. The boomerang flight is described by the methods of theories of aerodynamics and gyroscopic effects that express the kinetic energy of the boomerang motion and rotation. The mathematical model for the boomerang flight contains multifunctional and interrelated expressions of two theories, which manual solution is sophisticated, but solved by computer software without numerical modeling. The analytical solution for the boomerang flight describes its physics and presents a good example for the educational process of engineering mechanics and aerodynamics.
