Flight_Dynamics_Control_Human_System_Integration @SRW (Subsonic Rotary Wing)

Fundamental waves:
~ challenges due to the inherent instabilities of the flight vehicle, the aerodynamic and mechanical complexity of the system, and the operational environment
~ which is often obstacle-rich with poor visibility at low altitude.
~ new designs emerge, such as individual blade control (IBC), on-blade control (OBC), and variable rotor speeds
~ addressing the implications of higher-bandwidth control arising from IBC and OBC concepts, mitigation of dynamic effects resulting from rotor speed changes
~ reduced control response inherent to larger rotorcraft.
~ a flight control system
~ engine control
~ airframe/drive-train/rotor-load control
~ active rotor control of vibration and noise
~ vehicle health management
~ guidance for low noise operation
~ changing the rotor speed over a wide range, depending on the flight state and rotor capabilities
~ control methods to enable the benefits of new rotor dynamics while maintaining desirable handling qualities and aircraft responses
~ developing real-time predictive acoustic models that account for dynamic flight conditions and control inputs
~ precision guidance, navigation and control capabilities will be developed to enable data collection and evaluation for rotorcraft flight experiments,
~ including studies of acoustic properties, vehicle dynamics modeling, noise reduction and terminal-area operations
