| Abstract: | Trajectory optimization of a generic launch vehicle is considered in this paper. The trajectory from launch point to terminal injection point is divided in to two segments. The first segment deals with launcher clearance and vertical raise of the
vehicle. During this phase, a nonlinear feedback guidance loop is incorporated to assure vertical raise in presence of thrust
misalignment, centre of gravity offset, wind disturbance etc. and possibly to clear obstacles as well. The second segment deals with the trajectory optimization, where the objective is to ensure desired terminal conditions as well as minimum control effort
and minimum structural loading in the high dynamic pressure region. The usefulness of this dynamic optimization problem
formulation is demonstrated by solving it using the classical Gradient method. Numerical results for both the segments are
presented, which clearly brings out the potential advantages of the proposed approach. |
