2nd tutorial on how to model a wide-chord fan for a turbofan engine in CATIA


**** Steps 16 thru 35. *****
-
Step 1:
16. Make 2 more intersection points.
-
Step 2:
17. Create the shape shown, following similar procedure as the one before.
-
Step 3:
18. Make the profile shown on the zx-axis. The left-most point should be coincident with the H-axis. The right-most point should be coincident with the V-axis.
-
Step 4:
19. Make the line shown.
-
Step 5:
20. Make a Revolution Surface with both the profile and line you made earlier. The command for it is underneath the Extrude command.
-
Step 6:
21. Create a multisection surface. Make sure the closing points are correct.
-
Step 7:
22. Create another circle on the yz-plane.
-
Step 8:
23. Extrude the circle.
-
Step 9:
24. Split the fan blade and extruded circle. Click Other Side if the wrong part is cut out.
-
Step 10:
25. Fill in the tip of the blade.
-
Step 11:
26. Make the following spiral on the yz-plane.
-
Step 12:
27. Enter sketcher on the yz-plane and project the spiral, then offset it and close the ends.
-
Step 13:
28. Project the spiral sketch onto the spinner cone.
-
Step 14:
29. Extrude the projection.
-
Step 15:
30. Split the extrusion and spinner.
-
Step 16:
31. Fill in the empty space using the spinner as the Support.
-
Step 17:
32. Join the fan blade and its filled-in tip.
-
Step 18:
33. Create the rest of the blades by using Circular Pattern.
-
Step 19:
34. You are done! Go ahead and render it and admire your work.
