Momentum wheels are an efficient means to re-orient a satellite in orbit without using thrusters, which consume fuel from the satellite’s limited supply. In order to have a significant influence on a satellite’s orientation, however, a momentum wheel must be spun at very high RPM, often creating vibrations that have an adverse effect upon a satellite’s pointing accuracy. With this in mind, the SS/Loral Clinic team has employed numerical and empirical methods to characterize the composite assembly used to mount momentum wheels to SS/Loral satellites and explore damping techniques for this assembly.
