3D printed Propeller Shroud Kit

Posted on April 7, 2012 at 8:00am 14 Comments

I needed 3D printing capability to develop my Propeller Shroud Project

So, I conceived and print another kind of propeller shroud, and I 3D printed it. It is a kit made in ABS, consisting of 9 parts, to be glued around the hub, and screwed for the outer parts.

This shroud can be used as a blade protection, and could interact slightly with the airflow. Curious…


Propeller Shroud Project

Since several months, my interest in shrouded propeller is increasing, and I started to prototype a shroud.

What are the advantage of a shrouded propeller?

We can list 3 main points:

1 - Increased thrust, compared to the same unshrouded prop. (Possible gain 30% to 100%)

2 - Propeller protection. This adds security and allows to "touch" a wall, by example.

3 - Reduced…

I'm interested in any result data you have for the shroud.  Considering shrouded rotors on my project but have a few questions:
What is the "best" shape for hover performance. I see most VTOL ducted fan shrouds are an airfoil shape, not just a skin.

Is the increase in Lift/Power worth the added weight?
