Active turbulence cancelling

Spannend!
Wenn das in der Luft genauso gut funktioniert, wie in meinem Citroen XM - Oldtimer schon vor fünfunddreißig Jahren auf der Straße, lass ich mir das in den Flieger einbauen ^^
Das Prinzip scheint genau das gleiche zu sein, wie damals, und da war die EAlektronik schon sauschnell ...

Active turbulence cancelling



Active turbulence
cancelling
Turbulence Cancelling is able to reduce turbulence loads felt by passengers by more than 80% making use of counteracting control surface deflections.
Combined Feedforward and Feedback Control

Anticipating measurement of turbulence ahead of aircraft see Turbulence Load Prediction. High-dynamic lift variation low inertia flaps, see Direct Lift Control
Holistic Incorporation of Flight Dynamics

More than wing root moments.
Vertical Acceleration, Pitch, Roll, Wing Bending
Verified in manned flight tests

Flight tests with manned demonstrator aircraft have already confirmed the positive effects
Patented method and controller

First US patent granted, EP positive preliminary examination. Further patents in application
Direct Lift
Control

Direct Lift Control is achieved by dynamically adjusting the wing shape instead of rotating the whole aircraft - like birds do.
High-Dynamic Lift Control
No adverse Angle Of Attack Oscillation
Conventional Flaps or Morphing Technology
Turbulence Load Prediction

Turbulence Load Prediction enables to proactively anticipate turbulence impacts rather than only react after their occurrence.
Anticipating turbulence measurement
In-phase compensation signal
Pressure Sensors or Wind Lidar Technology
