Phase 3: Smart Structures 1992-1997
URI: Smart Structures Technology: Innovations & Applications to Rotorcraft Systems (92-97)
Objectives
- Develop a base technology to build
smart rotorcraft to actively control
- external/internal noise
- rotor-induced vibration
- transmission-induced noise & vibration
- aeromechanical stability
- performance and flight stability - Refine key technology elements of smart
structures for rotorcraft environment
- actuators, sensors (MEMS, fiber optics), controllers and power conditioning
