I had a discussion the other day with some of my peers and they were very keen on the fact the it is possible to change your orbit as desired using a single thruster and a three reaction wheels. The idea was that you point the thruster in any direction you want using the reaction wheels and boost it.
My intuition says that stability (maintaining a certain attitude) will be an issue as the reaction wheels are not able to withstand the forces of the thruster.
Assuming sufficient fuel is available and magnetorquers are available for desaturation of the wheel, is it possible to do orbital maneuvers with a single thruster on three-axis stabilized spacecraft?
