Science experiment on wind turbine generator
In this sustainable energy activity, aerospace engineer Jasmine Sadler builds a series of small-scale wind turbines, then measures their effectiveness with a hair dryer to create wind, a voltmeter to measure generated energy, and a single LED waiting to be powered. You'll design various blades to find out which produces the most energy, and put the wind to work for you! None Readily available Use caution when using the drill. Always wear. . Make a pinwheel to see how a very basic turbine works, and then use it to create electricity! If you don't have the electrical components, you can still do the first part of this project to see how wind can create mechanical force. >> Use this pinwheel pattern (PDF) to build your turbine.

Wind turbine shaft wear
The main forms of wear of the wind turbine main shaft bearings are abrasive wear, fatigue wear, and oxidative wear [36]. Secondly, the common lubrication problems of wind power bearings are analyzed from the bearing grease selection, lubrication mode, and lubrication status, highlighting the important influence of lubrication. . Wind turbine shaft wear is a common issue that can reduce system efficiency or even cause breakdowns. In the past, technicians often removed the entire shaft and shipped it back to a factory for repairs. That process cost time and money. Classified as three- and four-point designs, Figure 1 illustrates the nomenclature.
