A new guidance strategy in aerodynamic ascent path using air-breathing propulsion

The paper proposes the new guidance strategy in the aerodynamic ascent path. This guidance form has only four parameters comprised of Linear and Logarithmic functions. And the paper presents the guidance results for the practical application cases with certain constraints. The results show the guidance is well performed and satisfies the terminal boundary conditions specified. This guidance strategy does not include the optimization process aboard but solves a simple two-by-two linear algebraic equations along with forward integration. This strategy does guarantee the robust and real-time solutions, excluding any optimization process, and it is concluded quite practical.
