Aiming at the problem that the reusable launch vehicle (RLV) needs to be updated or iterated repeatedly during terminal area energy management (TAEM) stage trajectory design, a 3-dimensional (3D) guidance algorithm based on coupling coefficient is proposed. First, the longitudinal guidance algorithm is given in conjunction with the energy corridor method. Secondly, the lateral guidance algorithm is given through the design of ground geometric trajectory. Then, the concept and calculation method of the coupling coefficient in the TAEM process are given to quantify the turning needs of the aircraft, and this parameter reflects the coupling degree of the longitudinal and lateral motion of the aircraft. Finally, the 3D guidance algorithm is proposed, and the rationality of the algorithm is given theoretically. The simulation results show that the proposed 3D guidance algorithm based on coupling coefficients can reduce the number of iterations and quickly generate 3D trajectories that meet the constraints, and has broad application prospects.
