Blade loads acting on a rotor blade are usually determined taking into account strains acting thereon, which can be detected by strain sensors. To date, strain sensors have been adjusted using a rotor angle. Detection of the rotor angle is, however, often unreliable or inaccurate, and therefore no adequate solution has been found to date for adjusting the strain sensors simply and accurately. According to the invention, the problem is solved by a computer-implemented method for adjusting a first blade load measurement system having at least one strain sensor on a first rotor blade of a wind turbine, the method comprising the following steps: a first acceleration is measured by means of a first acceleration sensor; a first reference bending moment and/or a first reference axial force is/are determined based on the first acceleration measured; a first measured bending moment and/or a first measured axial force is/are determined based on values measured by the at least one strain sensor of the first blade load measurement system and a first adjustment parameter set, containing first initial adjustment parameter values, assigned to the first blade load measurement system; a first deviation of the first reference bending moment and/or the first reference axial force from the first measured bending moment and/or the first measured axial force is determined; the adjustment parameter values of the first adjustment parameter set for the first blade load measurement system are adapted

A method for deterring airborne animals to prevent collision between the airborne animal and a wind turbine. The method comprises providing data (PD) from at least one data source regarding at least one parameter relevant for an airspace of 5 the wind turbine. Next, analyzing said data (AD) according to an algorithm to determine presence of any one or more airborne animals in the airspace. In case it is determined that airborne animals are present, then changing (C_O) one or more parameters of operation of a rotor of the wind turbine, so as to cause the wind turbine to invoke an air pressure and/or wind velocity variation at a distance 10 of the wind turbine, e.g. upstream of downstream of the wind turbine, to deter the airborne animal from approaching the wind turbine. This may be a static increase or decrease in air pressure and/or wind velocity, or an increase in audible noise generated by the wind turbine, e.g. caused by pitching rotor blade(s) to generate more aerodynamic noise. Finally, returning (RNO) to a normal mode of 15 operation of the wind turbine after having caused the wind turbine to invoke the air pressure and/or wind velocity variation.

Curtailment or a complete stop may be used for some wind turbines to generate a safe flight path for the animal(s).

The templates include an inner overhang bracket template, an outer overhang bracket template, a central strut template, and a peripheral strut template, where in a first position at a first temperature, a first pair of the inner overhang bracket template and the central strut template is formed, and in a second position at a second temperature, a second pair of the inner overhang bracket template and the central strut template is formed. A second pair having an outer overhang bracket formwork and a peripheral column formwork is formed. Subsequently, the central post, the peripheral post and the overhang bracket are formed at different temperatures by means of the template.
