US - Patent: US Patent, Claims 20-25 relating to Fig. 24.
EU - Patent: EU Patent
The invention is an asymmetric wing profile with an adjustment device. The profile has a thickness and chord extending between the wing's leading and trailing edges. It comprises a three-part variable wing in at least one longitudinal section. The front and rear wing segments are connected to the middle wing segment via two hinges with axes of rotation. These segments are designed to enable rotational movement about an associated axis in relation to the middle wing segment. The middle wing segment forms a rigid housing that accommodates the adjustment device. The longitudinal element of the asymmetric blade profile is a hollow structure that provides an abutment for the adjustment device in at least one longitudinal section. The adjustment device contains an electric motor in the middle wing segment. With the help of this motor, the front and rear wing segments can swing in opposite directions. This creates a variable suction side to the asymmetric wing profile. The angle of attack of the profile line adjusts as the wing segments are swung in or out. In a preferred embodiment, the adjustment device is equipped with a step gear. At least one longitudinal section of the asymmetric wing profile is connected to the retaining element of the adjustment device, as are the middle wing segment containing the electric motor and the front and rear wing segments of the three-part wing profile. This connection enables the lift generated by the suction side of the variable wing profile to adapt to the aircraft's flight situation when the adjustment device is actuated.

Chapter 2: Pneumatically Actuated Wing Profile - Video.
US - Patent: US Patent
EU - Patent: EU Patent
DE - Patent: DE Patent
Here is a three-part rotor blade for the #ResGigaTube design: https://lnkd.in/et9qwc6S. The 600-meter-high wind turbine with a 200-meter diameter takes more than one minute to complete one rotation. At two positions aligned with the wind direction, the suction side of the rotor blade shifts from the inner side during windward rotation to the outer side during leeward rotation. Only a small adjustment force is required for this change within the range of these adjustment positions, also referred to as the vane position. Since the pitch change occurs over several seconds, there is no abrupt load change to the rotor blade, unlike with the Darrieus rotor. Instead, load peaks are reduced over the time required for the pitch change itself. This results in smooth, harmonious rotor operation. To accommodate the length changes of the contactless pneumatic actuators in the rotor blade, air is pumped from the outer actuator to the inner one and vice versa.

Chapter 3: Electrically Actuated Wing Profile - Video.
US - Patent: US Patent
EU - Patent: EU Patent
DE - Patent: DE Patent
This adjustable rotor blade can change its suction side about 60 times per second with the help of an electric motor. This innovative, patented technique can be applied to smaller versions of the #resgigatube project, as well as the #resmonocopter and #resstereocopter projects. A particular advantage is the contactless connection between the three parts of the #resblade.

Chapter 4: RES - Morphing Wing - Video.
This invention is a morphing blade profile consisting of at least three parts. The profile has a thickness and a chord extending between the wing's leading and trailing edges. In this embodiment, the front and rear wing segments consist of multiple parts and have a central joint chain. The kinematic hinge chains have an abutment formed by the middle wing segment and are controlled by pushrods. This enables the wing profile to transition from a symmetrical initial position to one that generates lift or downforce. The central wing segment forms a rigid housing that accommodates electrical actuators. The central wing segment of the symmetrical wing profile is a rigid, hollow structure that resists thrust, bending, and torsion. It serves as a rigid abutment for the nose and trailing edge segments. The adjustment device contains at least one electric motor in the middle blade segment. With the help of the motor(s), the front and rear wing segments can pivot in opposite directions. In a preferred embodiment, the adjustment device is equipped with a step-locking gear. This blade has many applications, including in wind and water turbines and as spoilers for sports cars. With a step-rest gear, the suction side of the rotor blade can elegantly align with a positive angle of attack to the flow. The step-rest gear is integrated into the middle blade segment with the greatest tread depth to achieve this. The asymmetrical wing profile enables a one-third increase in conversion power compared to a symmetrical wing profile.
