Active nutation control for spinning solid motor upper stages
Abstract
This paper discusses the application of a hydrazine-fueled, aft-facing thruster with pulses synchronized so as to neutralize coning on spin-stabilized rockets. Often used during long quiescent coast periods, the development of a more powerful system for overcoming dynamic-coupled disturbances during solid rocket burning is discussed. The contribution of vehicle modeling, disturbance characterization, and stabilizing models is shown, followed by evolution of the hardware from system requirements through flight results.
