Did you come up with this first or did Dyson? Did you check out their Dyson bladeless fan?

[leviterande]

@Nomoreidsleft this is different from Dyson. what I tried to achieve is a thrust reversal. the air is sucked in down through the blue funnel, achieve angular swirl momentum and climbs up out on the circular coanda surface creating very strong lift. this is the principle. it is a very hard thing to see

[wingnut4427]

seems like a pretty sound theory. I wonder how much thrust would be required to create sufficient lift. But what would happen if you placed equally spaced fly wheels within the structure moving with the air flow. Would it create enough of a difference to create a lift with minimum air flow ?

[leviterande]

I dont understand you well, but  actually no this is way froma sound theory. this is all done by goldshtik, A russian scientist, he died recently and i wanted to take on his results but it didnt work for me. My friend this is not a coanda effect! Here is what is supposed to happen if I remember it all , I gave it all up as it didnt produce results.

1. the air is sucked down through the center

2. the air pushed sideways and up to rotate throgh the lip and back again.

Very interesting.....I think the coanda effect should certainly come into play with this however.....If not then perhaps you should rebuild it making it so the sucked air will take advantage of the coanda effect...it would likely be more efficient....In fact I heard somwhere that a coanda lift style saucer would be more efficent if it sucked instead of blew the air. So I would not give up....It will likely take some mods to make it all work right.

this craft will use suction thrust

This isnt identical, but this "invention" has already been in use on most major jet aircraft since the 80's. Its called a thrust reverser. Mostly its used for braking after touchdown.

Who cares about a dyson fan

[ReneeNme]

That's one fancy vacuum cleaner you got there.

I have a photo of a helicopter type of craft that uses this same principle for flight, it was built in the late 1950's and uses a turbine with same flight characteristics as a helicopter. The top half looked like a flying saucer and the bottom half looked like a helicopter and at each of the four sides it had the same directional flaps as the Jean Louis Naudin Labs GFS UAV Coander Effect Flying Saucer model. Basically allot of people were experimenting with these type of craft at the end of WW2.

@Nomoreidsleft I think the dyson bladeless fan is not a dyson invention but an ion wind fan invented a long time ago.

[DoNotuseEbid]

ok I see how it works now, but how is this ever going to be more efficient than simply a ducted fan blowing straight down on top of a saucer?

[roper89]

If no one has already suggested it, you may be interested in looking at the work of Viktor Schauberger, particularly his 'repulsin'. Once you get past the conspiracy theorists er.. opinions, it is pretty similar.

[ihamoitc2005]

The way you've constructed it there's no way the exhaust air can be sucked back in. The reason is because what you're trying to build, believe it or not, I know what it is, requires unique geometry. There are formulas to calculate that.
