Coanda Effect Saucer (CES) UAV with an ArduIMU+ V2

Posted by Jean-Louis Naudin on December 4, 2010 at 6:20am

Here a project of a Coanda Effect Saucer (CES) stabilized with a 9D0F IMU. The CES UAV, propelled by an electric engine, uses the Coanda effect to take off vertically, fly, hover and land vertically (VTOL). There is no big rotor like on an helicopter and the flight is very stable and safe for the surrounding.

The Coanda Effect has been discovered in1930 by the Romanian aerodynamicist Henri-Marie Coanda (1885-1972). He has observed that a steam of air (or a other fluid) emerging from a nozzle tends to follow a nearby curved surface, if the curvature of the surface or angle the surface makes with the stream is not too sharp.

I use my firmware AutoStab v4.0 installed the ArduIMU+ V2 flat with a special mixer for this device.

Stay tuned on this blog, more to come soon,

You will find a FULL TUTORIAL for building yourself the Coanda Effect Saucer HERE.
I hope that you will soon enjoy to pilot yourself your own RC flying saucer...
Happey building and flights,

Hello Shyam Ramanath,

Thanks for your interest in my Coanda effect Saucer.

You will find all the plan for building and replicate yourself the Coanda Effect Saucer:
- in full size (scale 1/1) in DXF format HERE
- in XPS format (scale 1/1), ready to print on a A4 printer HERE

Regards,
Jean-Louis ..

Hi Jean-Louis,

I have a couple of questions. I was wondering if you could comment on the sensitivity of this design on scale. I.E. I where to just just scale this design down by 10% (so as to fit the particular material in have available at the local office supply store) would I get reasonable results?

The next question (so that maybe I could answer the previous question by myself at some point) do you know if there is open source CFD code available anywhere?

Any help would be appreciated.
