Abstract	NASA Dryden continues to support controls research through flight exploration. The F-18 Full-scale Advanced Systems Testbed (FAST) launched with a first flight of the research flight control system in March of 2010. This system is coupled with an Advanced Research Test System (ARTS) IV computer that allows for testing of auto-coded control laws from an engineering design environment. The first flight of an auto-coded nonlinear dynamic inversion controller occurred in September of 2010. Dryden has also acquired a Gulfstream III aircraft to serve as a flying testbed for aerodynamics. The first two initial experiments are a laminar flow glove to test the effectiveness of discrete roughness elements an adaptive compliant trailing edge flap for smooth lift and roll control. The X-48B Blended Wing Body vehicle has completed 80 flights and has moved on to a parameter identification flight phase that has 648 planned test points. The X-48C vehicle has completed wind tunnel testing and will investigate optimized intelligent control for performance and use of engine thrust differential for yaw control. The Stratospheric Observatory For Infrared Astronomy (SOFIA) has completed open telescope door envelope finding no significant handling qualities effects. The aircraft is ready to proceed with science missions and development of an autopilot controller that will provide tight tracking performance for science observations. A future project that is expected to fly at NASA Dryden is the Multi-Utility Technology Testbed (MUTT). This AFRL and Lockheed Martin partnership will demonstrate active flutter suppression and gust load alleviation. NASA plans to develop guidelines and methodology for active dynamic structural control and provide flight-validated aircraft models for academia. Dryden successfully led the test activities for the launch abort system tests at White Sands in New Mexico. The pad abort test occurred on May 6, 2010 and was extremely successful. Dryden involvement will continue with support for the uncrewed low earth orbit test of entry, descent and landing. Following that an ascent abort flight test is planned. Dryden continues to fly what others imagine.
