Open-Loop Simulation of Active Vibration Control of Electrically Controlled Rotor

An electrically controlled rotor (ECR), also known as a swashplateless rotor, is an active system that reduces the vibration load of through control while achieving primary by using trailing edge flap instead swashplate. In this study, effect 2Ω higher-order harmonic input on ECR investigated. First, analytical aeroelastic model established based Hamilton’s principle and unsteady aerodynamic with flapped airfoil. On basis, use to reduce The example analyzed sweeping amplitude phase control. analyzed. results show deflection has most significant vertical hub, there coupling between ECR, disrupts original equilibrium ECR.
