Development of 3DOF Longitudinal Dynamic Model of Generic Air-breathing Hypersonic Vehicle

Air-breathing Hypersonic Vehicles (AHV) presents futuristic ambitions for the global transportation on Earth, to Low Earth Orbits and in space in the coming decades. Nonlinear 3DOF generic AHV longitudinal model development is presented in this paper. It describes nonlinear modeling of 3DOF longitudinal model for simulation with trim condition. The aerodynamic coefficient model for the longitudinal model is also developed for the model simulation. The dynamic model analysis of 3DOF longitudinal model is analyzed expending the bifurcation method and considering the entire wide flight regime for the hypersonic flight.
