Design of Synthetic Experimental System for Helicopter Rotor Dynamics

A complete rotor/fuselage coupling system was established for experiments of helicopter rotor dynamics.The system was made up of five main parts:rotor,motor and speed control equipment,rotor steering equipment,hydraulic pump station,data collection and analysis equipment.The dynamic performance of rotor,all states of helicopter rotor/fuselage coupling and some faults of rotor can be simulated by the system.
