A blade for use in a wind turbine comprises a pressure side and suction side meeting at a trailing edge and leading edge. The pressure side and suction side provide lift to the turbine blade upon the flow of air from the leading edge to the trailing edge and over the pressure side and suction side. The blade includes one or more openings at the suction side, in some cases between the leading edge and the trailing edge. The one or more openings are configured to provide a pressurized fluid towards the leading edge of the blade, in some cases at an angle between about 0&#xb0; and 70&#xb0; with respect to an axis oriented from a centerline of the blade toward the leading edge.

An active sensing system for wind turbines is described. The sensing system may include a plurality of ports, a local sensing device and a load mitigation device and may be operably coupled to a control system. The plurality of ports, local sensing device, and load mitigation device may be operably coupled and configured to monitor air pressure on wind turbine blades, determine if proper sensing operation is occurring, and eradicate an obstruction if proper sensing operation is being prevented by the obstruction. Associated methods performing the sensing and eradication of the obstruction including purging and deicing are disclosed. Wind turbines and wind turbine blades with the active sensing system are also described.

An adjustable height pressure sensing port arrangement is provided. In some example, the pressure sensing port may be arranged on an airfoil, such as wind turbine blade. The pressure sensing port arrangement may include a pressure sensing port body and a spring arranged within the port body. The pressure sensing port arrangement may further include a pressure sensing port arranged vertically above the spring and a rotatable capture disk arranged vertically above the port. The capture disk may be rotated to adjust a height of the capture disk. Further, the spring may be arranged to force an alignment feature of the pressure sensing port into an alignment feature on the rotatable capture disk in order to secure the port and capture disk in place.
