Ornithoid with flexible-adaptive wing


Span - 2 m

Assembling of the wing is before flight.

From the video I can see that you are using Fanning and not FLAPPING movement. How are you doing the wing twist?

Kjell,

I use not Fan-effect, but Wing-effect.
The movements are OSCILATING.
The wing twist thanks to its flexibility.

What is the difference between Fan-effect and Wing-effect?

Regarding the only up/down motion on which this mechanism is capable IMO the wing twist along the span is nonsense.There isn't different flapping speeds along the wing span. Only flexibility needed is along the wing chord and probably will be helpful to implement your adaptive AOA system Velkov.

Good job. Reduce usage of aluminum ,it's heavy

The fan effects happen when the wing direction rotates or change the direction.
