Principal characteristics

MECHANICAL SYSTEMS

All mechanical designs seek structures that are balanced, whether with regard to their supports or, if they rotate, with regard to their rotation axis.

As a result, these wind turbines have three mechanical systems that compensate the power peaks caused by wind gusts. The first consists of the swivelling single-blade rotor, the second is the pendulum formed by the power train, and the third the selfsteering nacelle.

Thus, in our wind turbine, any disturbance caused by a wind gust is first absorbed by the swivelling rotor and then by the pendulum unit, whereupon the joint performance of both, along with its self-steering capacity, reduces the effect of the disturbance on the structure and the quality of power delivered by the fast shaft to a minimum.

TORQUE BALANCE

The joints between components can be rigid or have certain degrees of freedom. Disturbance causes the first to tense, whereas the second adapt to the disturbance by changing position, preventing tension.

The result of placing the masses of certain turbine components (generator, brake disc and multiplier) in a pendular position, hanging from a bearing aligned with the rotor shaft, allowing them to rotate until torque balance is achieved by the movement, is one of the mechanical principles of our design. This quality releases the stress from the nacelle, tower and footing.

INERTIAL STABILITY: THE FLYWHELL

All the components that make up the power train have internal components that are rotating at different speeds and accumulate kinetic rotation energy that is much greater than that of the pendular unit itself.

As we understand inertia to be the property of a body that opposes any change of position or rotation or displacement speed, we can say that when the sum of the inertias of the rotating parts pertaining to the various components that make up the power train (shafts and gear assembly and/or pulleys, if that were the case, brake disc and generator rotor) is greater than the inertia of the pendulum itself, the latter is the first to react against any disturbance to the torque, since it is the element with the least inertia. All the above ensures that the rotating masses are minimally affected and so is the speed ratio delivered to the generator shaft.

PORTABILITY

Wind turbines up to 335 kW are easily portable in 40' open top containers.
