Now extrude the airfoil face out just a bit short of the length of the blade. Then move the vertices around the perimeter of the ovoid face to approximate an airfoil shape. Then rotate it to approximate the inner blade pitch. Then scale it on two separate axes to make the end face ovoid in shape. To start the blade, extrude out from where the blade root face is on the hub. So onto modeling the blade portion of the propeller. Then press shift-L to select the region inside the loop. Look at your status bar to find the appropriate keystroke to enable it. You can also save a flatten step by using the flatten option while circularize is active. Then with the edge loop selected, circularize by 100%.
With the contour area still active, press L for Loop. This will be the starting area of the blade root. You can use tab and set Dx to 0 while the contour command is active. Select a region like so, and make a contour with 0 value. At this point there should be vertices selected. This will cut all the selected edges into 4 sections. Contour again for some control edges, and then collapse the n-gon faces to create a star at the center. Now lets hide the shaft and work on the ends of the propeller hub. Now is a good time to check the size of the propeller shaft cylinder and make sure it fits through the hub ok. In this case, we want 24 sections (to give some extra geometry to work with), a height of 0.1 (estimated 0.1m in reference to a drawing), and a diameter of 0.2m (also in reference to the drawing). This time right click on the cylinder option. Right click with no other objects selected. When making the propeller hub, we start with yet another cylinder. For other propeller types, you can follow the methods for a single piece propeller and cut/modify into separate parts as appropriate.

So I'll show how to model them in that manner. In the case of a carved wooden propeller, the hub and blades are a single piece. The propeller consists of the hub and blades. You can also use contour and collapse on the ends to keep the mesh all quads and tris.įile:PropellerTut 01.jpg Propeller It doesn't need to be modeled into the propeller itself (unless you really want to.) For purposes of smoothing, setting the edges at the ends to hard will keep it from distorting.
Depending on the vintage of the aircraft, this will either go into one end of the propeller or poke all the way through it.
