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