　　The stability of a helicopter rotor blade is a complex problem, involving aerodynamic, structural.material and geometric nonlinearities.Different mathematical techniques have been used in the past to study the aeromechanical and aeroelastic blade stability of various rotor configurations, at different flight regimes.These techniques include time history simulation (time integration techniques), parametric resonance analyses.
