On Dynamical Assembly of Nonlinear Uniaxial Atmospheric Flight Mechanics-Revisited in Frequency Domain

摘要: In previous research, the authors developed a nonlinear analytical solution of low order flight system using Volterra kernels in time domain. This paper revisits equivalent frequency A two-term truncated series, which is enough to capture quadratic and bilinear nonlinearities, for first second generalized single degree freedom systems. The resultant models are given form parametric study influence each linear term on kernel structures investigated. Periodic input then employed quantify qualify response characteristics. uniaxial pitch motion example presented as dynamic system. shows ability proposed Volterra-based model over linear-based predict, understand, analyze aircraft’s behavior.
