【Abstract】 The development of ascent guidance methods for liquid-propellant rockets is presented. The development background of ascent guidance methods is introduced from the perspective of flight mission requirements, control and computation theory and onboard computational platform. In the exoatmospheric part, firstly, the principle, the applying issues and the enhancements of the iterative guidance mode(IGM), the powered explicit guidance(PEG) and numerical optimal guidance are introduced in this paper. In the endoatmospheric part, the delta minimum guidance and common load relief strategies are introduced. The use of closed-loop trajectory generation in endoatmospheric guidance is discussed as well. Finally, the future directions of ascent guidance methods are discussed. Specially, the usage of numerical optimization and machine learning techniques are discussed in this paper. Ascent guidance methods are supposed to be more intelligent and numerically reliable in its future development.更多还原
