Abstract

Modified non-dimensional factors are used to derive a dynamic model of endoatmospheric hypersonic vehicles suitable for numerical optimization. Indirect adjoint method is applied for solving the two point boundary value problem of endoatmospheric ascent trajectory optimization. A method for initial value estimation is proposed and a vacuum solution is obtained first. Then the aerodynamic effects are introduced gradually and a convergence solution with control constraints is reached.. Simulation results are presented to demonstrate the effectiveness of this proposed method and its potential for onboard closed-loop guidance.
