Design Print Wind Turbine Blades. Steps with PicturesIntroduction Design Print Wind Turbine Blades. I am currently finishing a two year engineering course on wind turbine tech. Amazingly i made an rpm reading of 8. Demonstrate the working principle of a Wind Turbine, and make a working model of this device through free Wind turbine PowerPoint template for Engineering students. DIY Build your own 100 watt pvc wind turbine as a science project. Generate your own power from the wind. Kaplan Turbine A Mammoth. Kaplan turbines are suitable for power extraction when water energy is available at low head and high flow rate. Following are the. This instructable will guide you on the designing of the blade using solidworks and i  assume you have some basic experience if not on solidworks then some other 3d package.

Good LuckI am currently finishing a two year engineering course on wind turbine tech. Enjoy Step 1 Drawing the Turbine Blade. Open a new part on solidworks. To achieve an accurate outline shape of a turbine blade a good cheat was to import a profile drawing of one into the solidworks sketch then sketch over it tracing its curves using splines and lines. Download the blade profile i have attached then using  Tools Sketch Picture insert the picture of the blade. Step 2 Inserting the Picture. Insert the picture, using the property manager reduce or enlarge the picture to what ever size you deem necessary, i chose about 3 inches as it was just about the right size for the 3d printer remembering that this is only the radius, the over all diameter will be just over 6 inches. Step 3 Stations. Trace over the out line at each end of the blade with a vertical line. Wind Turbine Blade Template' title='Wind Turbine Blade Template' />Next, we are going to divide the blade into stations the reason will become clear later. Where the vertical lines cross the outline of the blade insert sketch points. Now using lines, arcs or splines trace over the outside of the picture using the points as joints, then delete the picture you inserted to reveal the outline sketch of your blade, do this in the side panel. Step 4 Adding New Drawing Planesnow using the 6 stations add a drawing plane to each enabling us to draw the 3d curves of the turbine blade. Step 5 Adding the Curves. Selecting each plane add a sketch. The sketch on plane 1 will simply consist of a semi circle to reflect it being the root end of the blade that attaches to the turbine Hub. Anti Deep Ze 0.1.

The straighter of the two long lines we traced from the photo is called the leading edge, when the turnine is rotating it is this edge which will be breaking the air as it rotates, It is for this reason i will make it more round than the trailing endge on the other side. I used spline lines with around 4 points to each, making them easier to manipulate to the desired shape and curve.

Just like the previous step select each of the planes to insert the curves in seperate sketches. This time the curves will be more pronounced to reflect the aerodynamic shape of the blade. Step 7 Adding the Surface. Now using Surfaces select Surface Loft and in Profiles select the splines on the top side starting with the semi circle at the root moving out towards the tip making sure to select them in order. Step 8 Make It Solid. Using Planer Surface and selecting the two lines seal off each end of the blade like below. Now we want to join the two long surfaces and the two Planer Surfaces we just created together, we accomplish this by using Surface Knit and selecting Try to Form a Solid. If you have been successful when the blade is cut into two sections it shou d be clear to see the inside is no longer hollow but a solid, this will be necessary for 3d printing later. Just finish the blade tip off by using Features Dome and select the face end of the tip, adjust the length to your own preference 0. This page is a diary about the 20 foot diameter wind turbine we built over the winter of 2006, and the 75 tower we built to put it on. A couple of years ago we built. Step 9 Thats the blade complete, the next few steps invole drawing the hub and a suitable tower, if you like you can draw them as seperate parts and join them in an assembly file which was what i did for printing however for the purposes of this lesson i will draw the hub here in the same drawing. I might add as we were doing this as part of a group of 1. Next use Features Extrude BossBase in both directions. The Fillet or Dome the front side the same side as the flat side of the blade. Using Circular Pattern select the Bodies to Pattern i. Step 1. 0 Finale. Using Features Combine now combine everything in the drawing to fix it all together and you are fin. Feel free to add all sorts of materials to the blades for some really cool renderings. Blade Part. 1 and the hub as i have drawn it in this instructable.
