Phase 4: Aeroacoustics Program 1998-2001
Smart Rotor Development
Application of smart structures technology
to actively control vibration, noise, stability,
performance and primary controls
Concepts: Flaps, active tab, active tips, active twist
Past: Carried out feasibility studies
- UM: successfully tested Mach-scaled models on hover stand in Glenn L. Martin wind tunnel
- Helped Boeing in their full-scale development (full-scale tests in 40x80-ft wind tunnel in 2008)
Present: AGRC Activities
- NASA-NRA: Swashplateless rotor using piezoelectric actuated trailing-edge flaps
- MURI from Navy: development of Galfenol actuators Support from Army/Navy/Industry: Development of innovative actuators, dampers and shock absorbers
Challenges:
- actuators stroke and integrity for rotorcraft applications
Blade Controlled-Disturbance Interaction Concept: New approach to mimic Blade Vortex Interaction
