INVESTIGATING THE TRAJECTORY OF THE ICE THROWNFROM THE HORIZONTAL AXIS WIND TURBINE

In this paper, we will study the trajectory and speed of Ice fragment from a rotating wind turbine. UsingNewton's second law and Euler's equations of motion, the governing equations including the transfer androtation of the fragment compact from the rotating part of the turbine. The calculations will be done usinga ballistic model, where the drag coefficient is kept constant on average and the lift forces are ignoredduring the flight. The trajectory, the speed and the impact energy of the ice fragment will be obtainedaccording to the initial angle of the projectile after solving the ODE differential equations using the 4thorder Runge-Kutta method. We will validate the obtained results with the available references. Theinnovations used in this research are, using a special method to obtain the initial conditions and solve theproblem, which can be defined and solved in any coordinates in the three-dimensional space,investigating the speed and energy of the ice impact, which play an important role in the amount ofdamage, terminal velocity check and simulation and calculation of ice rotation at any moment.
