Here's my question. What if you do the opposite? What if, rather than have the exit surface larger, you have the cone narrowing? As the air is forced into a narrowing chamber the thrust would multiply, right?
whatever shape you make you can only multiply volume of air but not thrust. basically you can get more air flowing but either it ends up being slower or you'll be pushing yourself downwards to compensate for that "extra" energy of the air
@@gregoryberzin3477 thanks for the reply. I was envisioning the cones on the back of jet engines when I made my comment. Honestly, I know nothing about propulsion, really I observe a lot and make what I think is a logical conclusion. Or, better said, I hypothesize based on observation and ask questions because I'm not a scientist doing this type of research.
Bad experiment. The fan in that dyson is not enough rpm for a drone. The proper experiment would at minimum be the changing of the motor to a size that is meant to lift a weight more than itself like in every other drone experiment. I have to give this a D for effort. Try a Drone Motor Calculator
Thanks for proving what's wrong with science these days. A poor understanding of what is already known leads to a poorly designed experiment which, in turn, results in misleading conclusions. Very useful as a teaching aid, but not the way you probably hoped. But don't let that stop you. Instead, get better. Many of the greats in science and engineering faced similar challenges in their early days. The important thing is to seek the answers in the first place.
if you block the airflow of the dyson fan then your are blocking the airflow and coanda effect, your evaluation is not accurate
Jetoptera is experimenting with bladeless part of wing lift.
Just what I was seeking. Thank you for sharing this experiment!!

The dyson fan needs room for flow boundary to allow for air flow multiplication
No, you need a certainly large volume of air coming a nto the chamber first then it shoots out in smaller open ing to achieve thrust

I hate bladeless fans. there are not bladeless the blades are just hidden

Some Fauci Science (tm) right here.
