Axial Wind Turbine
Wind Turbines and Dimensional Analysis?
[2009-07-17 15:25:20]

Q: Do dimensionless constants for a centrifugal pump not apply to a conventional wind turbine as well. Without modifying it in any way. (I think both machines are roto-dynamic, so in my mind it should be).

A: You are quite likely to find an answer here

wind turbine size/type?
[2010-01-07 17:50:32]

am trying to build a wind turbine that is capable of running an entire house from heating to tv however the location of that wind turbine is in a low wind speed area approx 5 miles per hour ,,,,my question is how many blades are preferable for low wind

for DIY, first task is to calculate how much energy you use on a daily basis, both peak and average.

Second task it to measure the average wind on an hourly basis.

Two decisions: 1. grid tie or lots of batteries. 2. If not

The Wind Turbine Bearings

Wind turbine bearings need to be corrosion resistant due to their constant exposure to the elements. Without this resistance the bearings ability would be slowly reduced, affecting its performance, which would then go on to cause the wind turbine to stop working....

Do I go with raidal Ball bearings or tapered roller bearings?
[2010-07-24 20:50:34]

I built a wind turbine that is on a vertical axis, and I am using magnetic levitation to support the axial load. Now I need conventional bearings to support the radial load, and I already tried pillow blocks and I was dissapointed. I want the wind turbine

For your application I would use sealed ball beatings.It's out in the rain so you need some kind of a seal with plain bearings,and you don't need tapered bearings unless you are supporting a large load.

Shaft Design For Compound Reverted Gear Train?
[2009-04-05 17:25:30]

My group and I are stuck on a design problem. We can not figure out how to get the dimensions of a shaft Shaft A is connected to a Wind turbine (this has a separate bearing system from ours so we don't have to worry about bending stress due to weight

First step is to pick the gears from catalogs. These are available with limited boss sizes, so select shaft diameters to mate to standard gear bosses. Size bearings to fit shaft and put in available space, best to select bearings with very low drag. Shaft
