| Abstract: | An important problem in Aeromechanical stability of a helicopter is ground and air resonance stability. This paper presents the structural modelingof blade, aerodynamic modeling, analysis methods of helicopter ground and air resonance. Past evolution in each subject are reviewed and future research needs are projected. Simple analysis is first presented and then refined analysis approaches are discussed. |
