Coanda effect
Coanda effect
(OP)
I am involved designing a helicopter of the notar type and I would like to know more about the effectiveness of using the Coanda effect to counteract rotor torque. I have looked at how Mcdonald Douglas use the Coanda effect and it seems to be rather complex component wise. Would the Coanda effect work with larger volumes of low pressure air. The only helicopter that I can find that uses this concept is the Mcdonald Douglas, are there any others?
Any help much appreciated.

If you wanted to try out a number of alternatives maybe talk to the aerodynamics boys at MIRA Ltd. I don't work there anymore, but they did some pretty varied an interesting work - all with the strictest of security, for a number of global clients.

I wish you luck with your project - sounds interesting. Is it anything that can be openly discussed?

There is another interesting aplication of Coanda effect studied for a long time by NASA:
Circulation control airfoil
You can check the "SPORT AVIATION" magazine from 28 March 1988 for DOUG GARNER's article; it seems to have the formulas you need!
I hope this is of help.
