摘　　要：The set of the orbital angular-momentum reversal,or H-reversal,sailcraft trajectory was born as a type of unconventional precursor interstellar mission trajectory by using highperformance solar sails.Starting from an outline of the H-reversal sail trajectory,this paper mainly focuses on the 2D reversal-mode solution to the general solar-photon sail motion equations.The feasible region for H-reversal trajectories in fixed sail attitude angles is illustrated.Some interesting applications of the H-reversal trajectory are presented in detail to show its advantages.As a special case,a precursor interstellar probe can be delivered with a constant sail orientation in the H-reversal trajectory to be compared with the direct-motion sail flyby of the Sun.Of importance are the heliocentric periodic orbits in double H-reversal modes,obtained via both fixed and time-varying sail attitude angles.Two more applications involving H-reversal trajectories are discussed in terms of asteroid deflection and transfer trajectory to rectilinear orbits.Finally,some items of the mathematics behind the 3D motion-reversal trajectories are summarized.
