Abstract

A stability experimental method of ground and air resonance for bearingless rotor on test-bed was investigated, the test principle and method were presented. A 4-m diameter rotor model was used to investigate aeromechanical stability of ground and air resonance and the results were compared to theory, the measured lead-lag regressing mode damping agreed well with theory. The results indicated this method has advantages of reliability and validity,improves test security, achieves the desired purposes, and provides effective technology for the bearingless rotor helicopter stability test.
