Zinc halogenated-triazolate oxalate metal-organic framework (MOF) sorbents constructed fully or partially with halogenated triazolate ligands, zinc, and a bidentate carboxylate are described herein along with their method of synthesis and its application for sorptive gas separation of carbon dioxide from a feed gas. The described zinc halogenated-triazolate oxalate MOF sorbents are suitable for applications where the feed gas has a reduced concentration of carbon dioxide and reduced levels of moisture. As compared to the prior art, the method of synthesis is environmentally friendly.

Various air deflector shapes, sizes and configurations for use in a load compensating device on an airfoil are provided. The air deflector arrangements are configured to alter the airflow around the air deflector in order to affect sound or acoustics associated with the air deflector when deployed during operation. Some example configurations that may alter the air flow around the air deflector include air deflectors having a plurality of apertures, air deflectors including a scalloped edge, and/or air deflectors including a plurality of protrusions extending from a portion of the air deflector.

A method for actuating load management devices on an airfoil. The method comprises (i) determining, by an airfoil control device, operating conditions at an airfoil; (ii) determining, by the airfoil control device, a number of load management devices to be actuated according to the operating conditions, wherein the number of load management devices to be actuated is less than all of a plurality of load management devices on the airfoil; (iii) determining, by the airfoil control device, an actuation sequence for actuating the number of load management devices, and (iv) actuating, by the airfoil control device, the number of load management devices according to the determined actuation sequence.
Systems, apparatuses, and methods are provided for actuating one or more load management devices on a wind turbine and/or a wind turbine blade. Each actuator may exhibit one or more beneficial qualities including appropriate actuation speed/force characteristics, size and/or weight characteristics, and/or increased reliability and consistent operation in a variety of operating conditions. According to some aspects, the actuator may be a direct pneumatic actuator, a ramp slide pneumatic actuator, a scissor actuator, a linear induction actuator, a belt actuator, a closed cam follower actuator, a screw drive actuator, a solenoid actuator, a rack and pinion actuator, a cylindrical cam follower actuator, a Y-belt actuator, an offset rotary drive actuator, a tape style actuator, a rigid tape actuator, a deformable membrane actuator, a memory alloy actuator, and/or a crank slide actuator.
A load compensating device for an airfoil rotor blade. The device comprises a housing arranged on an interior of the airfoil rotor blade. The airfoil rotor blade defines an aperture and has a recess surrounding the aperture formed in a surface of the airfoil rotor blade. The housing is mounted in the aperture. The device further includes a mounting plate received in the recess surrounding the aperture, wherein the mounting plate includes a tab extending downward from a first end of the mounting plate and the tab is configured to distribute force from the load compensating device to the surface of the airfoil rotor blade. The housing is configured to float between the mounting plate and recess.
