| Abstract: | A linearized mathematical model of a coaxial helicopter for the stability and control system analysis is extracted from numerical linearization of a non-linear mathematical model with the help of small perturbation theory. The computational results of a sample coaxial helicopter stability and control derivatives are well agreement with those from Russian model. The research on stability of a sample coaxial helicopter is presented by using the obtained linearized mathematical model. |
