The paper is focused on an equilibrium analysis of the HOPE-X with six degrees of freedom nonlinear equations of motion and nonlinear aerodynamic data. The analysis is made primarily by using the continuation method, and the problem formulation for the method is described. Results are compared with those of two types of simplified analyses to suggest that rigorous analyses are necessary for control system development. Stability analyses of the obtained equilibrium branches are then undertaken to pose the problem that the vehicle has no attractor in a subsonic range under investigation. Future works are finally referred to with regard to the continuation method and the speed range of the vehicle to be pursued further.
