A Low Speed Model Analysis and Demonstration of Active Control Systems for Rigid-Body and Flexible Mode Stability

Abstract

An existing low-speed SST flutter model was modified to include two hydraulic aileron control systems and a horizontal stabilizer system. Wing mode flutter suppression systems were analyzed and wind tunnel tested, using wing strain gages and the aileron systems in the active control feedback loops. Rigid-body stability systems were theoretically analyzed and experimentally synthesized using body-mounted sensors. Variable rigid-body stability was achieved through a remote-transfer water ballast system. The results of parallel analysis and wind tunnel tests, the methods of approach, the problems encountered, and a list of recommendations for the advancement of the active controls technology are reported in this document.
