Abstract
Sultan wind turbine v.5 is a vertical axis wind turbine with a combination of savonius and darrieus types. This wind turbine is the development of previous wind turbine studies. To find out the value of the moment of inertia coefficient and the value of moment inertia rotor sultan wind turbine v.5 the experiment was carried out using an inclined plane. Rigid objects that roll do a combination of two movements at once namely translational motion and rotational motion. Inertia moments of rigid bodies are generally formulated as I = kMR2 where k is the coefficient of moment inertia. In this experiment, the object used is the right and left rotor of the sultan wind turbine v.5. Data collection is done by video recording when the rotor rolls on the inclined plane. The videos are analyzed using tracker software. The motion on the rotor in the videos subsequently tracked to produce position and time data. The tracking method are in two ways, namely auto-tracking and manual tracking. The tracking data is made into a graph resulting in a linear velocity relationship with time. Those graph are analyzed which produces the A gradient value. From the results of calculations and data analysis, the coefficient of mement inertia right rotor is 4.36 and the left rotor is 4.677. The calculation value of the inertia moment right rotor is 2.26 Kgm2 and the left rotor is 2.42 Kgm2.
