Abstract To resolve the trajectory design problem of morphing glide vehicles during Mars atmospheric entry, this study investigated a trajectory optimization method that allows the morphing degree to be used as an auxiliary control variable. An aerodynamic model for the morphing vehicle was established, and the Mars entry optimal control problem was transformed into a nonlinear programming problem using the Gauss pseudo-spectral method. Under multiple constraints, trajectory optimization simulations were conducted with the flight range taken as the performance index. Simulation results show that incorporating the morphing degree as a control variable enables effective trajectory planning for Mars entry. Compared to fixed-configuration vehicles, the morphing vehicle reduces drag through adaptive shape transformation, thereby decreasing mechanical energy loss during the initial flight phase. The flight range was improved by 10.4%, achieving superior performance metrics.
