Use the string to pull the extensions to the wing root.
With the exception of the wing root rib all ribs are put freely rotatable on the spars.
Rods with spherical bearings to pitch the wing root.
This setting corresponds to about 78 mm aft of the wing root leading edge, measured either side of the fuselage.
The adjustment is affected by the torsion lever at the wing root.
But also a rotation of the wing at the wing root around its longitudinal axis changes the lift.
The pressure willbe adjusted with the inlying lever InH at the wing root.
For a lift increase near the wing root birds can probably use still further possibilities.
Overall, the lift distribution is smaller and more shifted towards the wing root.
Retrieve the servo extension at the wing root near the aileron.
Pull the leads for the aileron and flap servos through the opening in the wing root.
In this case, the angle of incidence at the wing root remains constant during the whole flapping period.
The complete PCB with the multipole connector can be fixed in the wing root of the model.
If nothing changes at the wing root, in this way the center of lift is displaced to the wing root.
Use the string to pull both the aileron andfl ap servo leads through the hole in the wing root.
It increases considerably the angle of attack at the wing root in the lower wing position. But then it reduced the angle once again during the upstroke.
It would then be shifted on the top of the stroke to the wing tip andon the bottom point to the wing root.
About a rotation of the wing root during cruising flight of large birds or other measures to increase lift during wing upstroke is nothing reported.
Thus sufficient lift can also be generated during upstrokehere the angle of attack is increased near the wing root.
The pictured differences of lift at the wing root results only from different induced downwind angles please look at the diagram Downwash distributions.
In the upstroke increase anddecrease of the angle of incidence move like a wave from the wing root to wing tip.
When rotating the wing root(here about +6 degrees), the negative thrust remains relatively small, despite almost the same lift as in gliding flight here approximately 80.
The Centre of Gravity(CG)should be about 74 mm from the leading edge at the wing root, measured either side of the fuselage.
At the upper reversal point of the stroke motion it is shifted towards the wing tip andat the bottom point to the wing root.
Its starting point moves back and forth at the trailing edge of the flapping wing during a flapping period,at the upstroke towards the wing root and at the downstroke towards the wing tip.
The aircraft was similar to the N-20.10, but had one conventional engine, a Rolls-Royce Avon or Armstrong Siddeley Sapphire turbojet in each wing root.
One can see the rise off ground of a rubber-powered ornithopter andparticularly the changing of the angle of incidence at the wing root recommended by Erich von Holst.
Indeed, the distribution of the transverse forces along the wingspan resembles the diagram 4,however with a significantly stronger shifting of the upstroke lift to the wing root.
To avoid the accelerating forces in the final stroke positions flapping wings rotating on a cone-shaped shellwhere sometimes built whose apex lies at the wing root.
