An investigation of a synergetic maneuver, which uses a combination of rocket propulsion and aerodynamic forces to obtain plane changes for orbiting spacecraft. Each phase of the maneuver — deorbiting, pullout, glide, ascent, and injection — is analyzed by the use of approximate closed-form solutions to the equations of motion, when these equations cannot be solved analytically. The synergetic maneuver and a method using only propulsive devices are then compared.
