The goal of this paper is to set up a software-calculating helicopter dynamic, which can derive the linearized model from any trim point within the global flight envelope, so that we could afford nearly complete six degree-of-freedom model of a helicopter plant. We will establish the nonlinear and linear mathematical models of helicopter, which are the fundamentals of helicopter simulation and control. By using the principle of forces and moments equilibrium, we determine the trim points of different helicopter's flight conditions. At each trim point, the linearized model can be derived by Taylor's series expansion. Our contributions will reduce the iteration numbers significantly and increase the modeling accuracy by proposed parallel trim procedure.
