AN IMAGE PROCESSING METHOD TO DETERMINE THE DAMPING EFFECT PRESENT IN THE MOMENT OF INERTIA MEASUREMENTS PERFORMED ON AN AILERON

This paper focuses on a practical, low budget image processing approach developed to quantify the damping effect on moment of inertia measurements performed withan inverted torsional pendulum. Several measurement cases were realized to measure the damping effect on MoI measurements of an aileron. Method takes advantage of an ordinary camcorder and a software tool to obtain the oscillation profiles. The damping effect was quantified based on free vibration having single degree of freedom with damped response. Based on the measurements and the results obtained by the methodology, it has been seen that the error due to the assumption of undamped conditions affects the measurements far less than the error sources embodied in the inverted torsional pendulum method
