Abstract	NASA Dryden flight research center continues to fly research vehicles with a significant guidance, navigation and control component. Manned vehicle programs with flight activity in FY05 include the F/A-18 Active Aeroelastic Wing (AAW), the F-15 Intelligent Flight Control System (IFCS), and the C-20 (GIII). The AAW aircraft will complete the phase II series of flights this spring, where the project team is evaluating advanced control law design methodologies coupling aerodynamic and structural deflection models. This summer, the Gen II adaptive control laws will begin research flights, evaluating a dynamic inversion control law with a modified sigma-pi neural network for damage adaptation. There is a significant interest at DFRC in UAV flight research as well. For small UAVs, flight test has been completed for a cooperative network team project, and just begun for an autonomous soaring effort. The Network UAV teams project was a RSCA-funded partnership with NASA Ames. The final flight series included autonomous path re-planning, coordinated group transit (boid), and 4-d waypoint management. The autonomous soaring effort is focused on demonstrating a significantly increased endurance for small, electric powered UAVs by utilizing atmospheric energy (primarily thermals). 2004 was also a banner year for the X-43A Hyper-X program with a successful Mach 7 flight in March and a Mach 10 flight in November. Although the fate of hypersonics within NASA is not clear, DFRC is working with the project partners to collect and disseminate the technical lessons learned for future applications.
