Active Flexible Wing (AFW) Technology

Abstract

This report documents the results of the transonic, active control wind tunnel program. The wind tunnel model along with its physical characteristics (flexibility, vibration modes, and control system transfer functions) and the wind tunnel test procedures are described in this report. In addition, the results validated the flexible control power and verified the analytical tools used for design. Results of active control designs and tests, roll control, maneuver load control, and structural mode control designs and tested are also included. Finally, an assessment of the AFW technology provides recommendations for future research and development. Keywords: Active flexible wing, Controllability, Wing roll control, Wind tunnel testing, Transonic aeroelastic control effectiveness, Active control design and tests.
