Thrust Test with Smoke

thanks.
0:35 propeller is on

nice video. i'd love a top view of this experiment

A full (albeit, edited) video of all the propeller tests and the data you gathered would be interesting. I can't help but to think other factors may have spoiled this test like:
1) Clearly there was some kind of device pushing the air. In a propeller test, it seems you would not only NOT need such a device, but the use of such a device might skew results.
2) The area behind the propeller is very small. In real-world scenarios, there would not be a tunnel funneling the air behind the prop. It would be interesting to see what happens to the air in a more open situation. It would also be interesting to see how *far* the air remains in a cylindrical pattern before breaking up. It would be interesting to see smoke pattern dispersion from the TOP side of the propeller. It would be interesting to see at what RPM the propeller loses efficiency - or if it ever loses efficiency at all.

That is really cool guys.

thrust test?

[@paradiselost9946]

beautiful.
only problem?
i wanna see it with the aircraft behind it. rather than a square box.
*returns to searching...*

Can you please tell what type of sensors were used in the experiment to get angular velocity and thrust.

Cover the engine ! its a drag
