Coanda Thrust Experiment

More at http://www.laesieworks.com/ifo/GN/GN003.html
This experiment was to create thrust with, in a "coanda effect" style. On top of that disc, a jet of air is creating lower airpressure. The ambient airpressure under the disc is providing the thrust (and not a ground effect).

Coanda method takes up too much space. xcopter is more practical.

[Trebseig]

The coanda method does us a lot of surface, and that has weight, and drag. But I wouldn't say an Xcopter (a helicopter that can fix its rotor to become a wing) is more practical. The coanda method is a very simple and safe construction. If you look at the construction and aerodynamics of a helicopter, it's hard to believe it will fly, especially forward flight seems impossible (if you never saw it for real). But it flies.

lol is that motor from a vacuum cleaner?

[DBZass]

scared the fuck outta me when it started

[Dongskie2]

use counter rotating rc brushless motor and install the turbine thingy

@xerox165

No, it's a Flying Vacuum Cleaner . :)))

@mrkethy1

Well said!

[snoopydunk]

That's a vacuum cleaner engine , I destroyed one. great idea thpough.

How long does it take to moon? 2 days?

[MrAwsome514]

You may want to place a gyroscopic weight inside being spun in the reverse direction as the blower fan as a counter balance to the rotation that the frame would get from the motor the blower is run on. For stability purposes.

@Trebseig yup

this is real coanda effect. lot of other "coanda-planes" got a big prob mounted => like kind of helicopter ...

nice video/experiment
