TECHNOLOGY TRANSFER OPPORTUNITY: Aerospace Vehicle Entry Flightpath Control (TOP2-303)

NASA s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: The state-of-the-art in hypersonic entry Guidance and Control (G&C) is traditionally based on rigid entry vehicles, like the Orion capsule, Space Shuttle, etc., that use a Reaction Control System (RCS) to control the bank angle of the vehicle. However, for future high mass missions to Mars, advancements in hypersonic aerospace vehicle design, and evolving science goals, are stretching the performance capabilities of traditional entry systems. NASA s Pterodactyl team at Ames Research Center has developed a novel yaw-to-bank control system for a non-traditional vehicle configurations, such as a Deployable Entry Vehicle (DEV) that can be folded and stowed. The approach provides vehicle stabilization, steering, and precise targeted landing. This control architecture is agnostic to control actuators and can be used with any aerospace vehicle with a strong dihedral effect and/or different guidance control variables. This novel flightpath control system exploits the dihedral effect to control the bank angle of the vehicle by modulating sideslip. Exploiting the dihedral effect, in combination with significant aerodynamic forces, enables faster bank accelerations than could be practically achieved through typical control strategies, enhancing vehicle maneuverability. This approach enables vehicle designs with fewer control actuators since roll-specific actuators are not required to regulate bank angle.
