rotor blades are adjusted by hydraulic cylinders. This is located directly in the rotating hub of the wind turbine. The system solution from HAWE consists of the cylinders, hydraulic accumulators, control blocks [...] weather conditions. The temperature span may vary from -25°C to +55°C without affecting the system’s performance. The system offers easy installation and high reliability due to its rapid response and [...] control of the typical brakes in wind turbines, this also includes the control of the rotor blocking cylinders.

servo cylinders ( Figure S 53 ) are used with two construction designs, which differ in terms of the bearing of the piston and piston rod: 1st cylinder with hydrostatic bearing and 2nd cylinder with contact [...] Servo cylinders, together with the load, form a system capable of oscillation with a relatively low natural frequency (between 10 and 100 Hz) and very low damping, between 0.05 and 0.2 ( Figure S 54 ). [...] As their stiffness also depends on the oil volume in the cylinder, they are not easy to handle in terms of control technology.

Euler's formula applies in this regard to cylinders arranged vertically [...] application of centric forces. where l = the smallest axial planar moment of inertia s = free buckling length (see Figure K 12) S K = safety factor (safety in terms of buckling) In addition to the basic scenario [...] (Figure K 12). Mounting scenario 2 applies in most cases, so that s = l. Particularly thorough calculations are required for horizontal cylinders or those tilted at a considerable angle, since the bending stress

leaks from directional valves with a piston structure between the consumer (e.g. cylinder ) and the directional valve ( Figure S 71 ).

They represent characteristic operating pressure-time curves for cylinders and make it easier to categorise cylinders with widely varying requirement profiles in relation to their load.
