DYNAMIC MODEL OF ROLLING PROCESS FOR MODEL-SCALE HELICOPTER
Development of a reliable high-performance helicopter-based unmanned aerial vehicle requires an accurate and practical model of the vehicle dynamics. This report describe the process of roll and pitch dynamic modeling of model-scale unmanned helicopter under hovering. In addition to standard helicopter flight characteristics, the model explicitly accounts for the stabilizer bar, which has a strong influence on the flight dynamic and is widely used in model-scale helicopter. Particular emphasis is placed on the mathematical modeling of the main rotor and Bell-Hiller stabilizing bar. Simulation result are presented and discussed.
