| Elastic rotor blade increases efficiency |
|
|
With elastic rotor blades reduces the load on the turbine generator, while the efficiency can be increased. Siemens will 2012 bring new rotor blades for wind turbines, which reduces the stresses on the generator. The leaves are thinner and more elastic than today's blades and twisting slightly when they are burdened by the wind.
The company describes the loads on an offshore wind farm of up to 100
tons per second. Elastic blade can more easily adapt and reduce
pressure loading significantly. Component fatigue is reduced and life
expectancy increases.
Alternatively, you can benefit by extending the leaves as compared to if they are rigid, and thus increase energy output. The new blades are introduced in the U.S. next year, with its 53 meter four feet longer than the previous model, which is 5:05 per cent higher energy output.
By making the blades thinner saves material and weight, the new leaves
is 500 kg lighter than the previous generation. This has been achieved
through computer-based optimization and practical tests.
Manufacturing technology will also be automated to a greater extent than
before, and it hopes to reduce production costs by up to 40 percent.
All these factors will contribute to wind-generated electricity can be
cheaper than electricity from coal at the end of this decade.
