Starship is a new generation of reusable space transportation system developed by Space Exploration Technologies Corporation (SpaceX). The landing process of this type of spacecraft, which has the characteristics of large attitude maneuver, multiple constraints, and high accuracy requirements, is different from that of traditional spacecraft. The dynamics of the flipping and landing phase of the Starship-like aircraft is studied firstly, and the response of engine gimbal angle is introduced into the dynamics to suppress the oscillation of engine gimbal angle. Then, based on the convex optimization method, an optimization algorithm for the free-final-time flipping and landing trajectory of Starship-like vehicles is designed, which can consider the attitude maneuver and typical constraints. In order to improve the convergence of the algorithm, virtual control and penalized trust region are used, and a method for initial value selection is given. Finally, numerical examples are provided to analyze the influences of initial value selection method, the response of engine gimbal angle, engine number, and the selection of optimization objective functions on the flipping and landing phase.
