Abstract	An overview of the NASA Launch Vehicle Adaptive Control (LVAC) Flight Characterization Experiment is presented. This project is designed to exercise novel adaptive control strategies currently included in the Space Launch System (SLS) Flight Control System baseline by simulating the dynamics of the launch vehicle ascent environment using a modified F/A-18 surrogate aircraft. The control system under test is designed to adapt to unexpected parameter variations using forward loop gain modulation, and is capable of responding both to low-frequency model tracking error as well as undesirable high-frequency control-structure interaction. Preliminary simulation results are presented along with plans for the upcoming series of research flights at Dryden Flight Research Center (DFRC).
