Floquet analysis is the primary mathematical tool for helicopter stability investigations.
Helicopters are susceptible to different types of aeroelastic instabilities, and the prediction of stability margins or damping levels is analytically demanding and computationally expensive. Floquet analysis is the primary mathematical tool for helicopter stability investigations and has two parts. The first part is the trim analysis of computing the control inputs and vehicle orientation for required flight conditions, as well as the corresponding periodic or steady-flight response. The eigenanalysis of the FTM gives the damping levels. T. Although computationally intensive, these integrations lend themselves well to parallel implementation.
