Solutions for Rapid Yaw Maneuvers for High L/D Hypersonic Vehicles

GoHypersonic Inc. (GHI) and the University of Dayton (UD) are proposing to the Missile Defense AgencyÆs (MDA) Small Business Technology Transfer (STTR) topic Rapid Yaw Maneuvers for High lift-to-drag (L/D) Hypersonic Vehicles. We will investigate a variety of novel control schemes for non-axis symmetric high L/D vehicles which provide the force necessary for rapid yaw maneuvers. These investigations will address the feasibility of the proposed control layouts and establish the required engagement envelope for mission success. The technical problem we seek to tackle is the slower yaw maneuver response times encountered by hypersonic vehicles with non-axisymmetric lifting bodies, in contrast to finned vehicles with conical bodies. Although non-axisymmetric lifting bodies offer the advantage of higher L/D ratios, their yaw maneuver response during bank to turn maneuvers is relatively slow compared to skid to turn maneuvers. As hypersonic technology advances and non-axisymmetric lifting bodies gain prominence, it becomes crucial to optimize their maneuverability without sacrificing the high L/D ratios they offer. Improving the yaw maneuver response times for these vehicles is essential to ensure their agility, mission capabilities, and overall performance. Our proposal aims to develop innovative control surface solutions or hybrid configurations that can effectively decrease the time constant for maneuvers while preserving the high L/D characteristics of the vehicle concepts. By focusing on minimizing the mass, volume, and drag impacts from control surfaces and/or other mechanisms, we shall design solutions that enable yaw maneuvers with time constants comparable to finned cone of similar size. Design and computational studies will allow us to estimate maneuverability and kinetic energy loss during maneuvers at various Mach numbers and altitudes. Based on our findings, we will refine one or two preferred designs that offer improved maneuverability. By addressing these technical challenges head-on, we aim to develop innovative control schemes that enhance the maneuverability of hypersonic vehicles with non-axisymmetric lifting bodies. Our approach combines in-depth research, advanced mathematical modeling, computational simulations, and rigorous performance evaluations. We understand the importance of minimizing mass, volume, and drag impacts, and will prioritize these considerations throughout the design and evaluation process. By advancing beyond the limitations of the cone fin approach and exploring alternative control mechanisms, we aim to provide a leap forward in the field of rapid yaw maneuvers for high L/D hypersonic vehicles. Given our teamÆs combined expertise, research capabilities, and dedication to advancing hypersonic vehicle technology, we are confident in our ability to deliver innovative solutions, rapid design development, and rigorous assessment.
