DOI: 10.1109/taes.2025.3621173

Abstract: This article presents an optimization-based midcourse guidance methodology for variable-flow ducted rocket (VFDR) missiles. While classical trajectory optimization approaches are capable of addressing the inherent nonlinear dynamics and flight constraints involved in the midcourse guidance… read more here.
