It is one of the oldest energy suppliers of humanity: the wind. What started with windmills for grain is currently culminating in gigantic wind turbines, which globally drive the departure from fossil fuels.
China has set up a new record in the field of systems to water (once again): the leaves are almost as long individuallyLike the Cologne Cathedraland in the diameter of the rotor they are enoughan die Titanicamazed.
This aircraft from Radia is not intended for wind turbines to water, but intended for the colossus of the future. It should transport such gigantic rotor blades into remote angles of the earth - and that would be.
Giants among themselves in the Far East
TheChinese state company CRRChas set up a wind turbine, the hub (where the rotor blades are attached) is located at a height of 151 meters. The diameter of the rotor is 260 meters. The Titanic was 269 meters long. The Cologne cathedral is 157 meters high, which is about 30 meters more than a single leaf long.
The performance of the system estimates CRRC with 20 mW. A little more visual: A revolution of the system should provide as much electricity as an average Chinese family uses within rough three days (viaHeise).
Very simplified, but the height of the hub determines how steadily and strong the wind strips over the rotor blades. Because the higher, the more even and stronger it blows. The length of the leaves in turn determines how much of this potential.
Average offshore wind turbines in Germany-the latest extension(via wind-energie.de):
- Perfomance:10,4 MW
- Rotordurchmesser:186 Meter
- Nabenhöhe:96 Meter
CRRCOtherwise it is known in another field: high -speed trains. However, such combinations are not unusual, for example Siemens. The traditional German group also builds wind turbines, trains and much more.
The competition is not on the spot - but it also comes from China. In August 2024, the Mingyang group also set a 20 MW giant with rotor blades of at least 260 meters in diameter. However, the prototype did not deliver electricity for long. For unknown reasons he wasInformation from the groupdestroyed in December.
Previously, the also Chinese company Dongfang Electric Corporation had the rod: also around 260 meters and 18 MW (viaTopagra).
Mingyang already has the next arrow in the quiver in his hand: a wind turbine is to be erected at some point in 2025,that reached the height of the Eiffel Tower(Blatt plus tower). The diameter of the rotor is said to span 310 meters and the power is 22 MW.
The core problem that manufacturers of offshore wind turbines worldwide are not the height of the tower. Also, neither the materials nor the length of the rotor blades are currently reaching an insurmountable border. The producer is the placement at the worst headache. Because everyone would like to have their turbines on the open sea. The most wind blows, so the latest trend is called: swimming instead of fixed stilts or foundations. But the developments here are still at the beginning.
