This is Paolo from Italy and below you see my Sardone build.
It is a Jet setup, with many parts inspired by @PacificMeister, everything in the 60mm pipe as I saw on the elegant approach of @VeFoil.
It Run With Lipo 16S, SSS 56114 360KV, Esc Flier 400A
Before to put it under a board I’m testing in a test bed where I found some main weakness which I tried to address.
Now I have a very strong Carbon fiber Impeller of which I’m very proud of (Diameter 55.5mm, Pitch 44mm). It is inspired by @Virus which videos I study frame by frame
As a test bed I have a bin full of water with a cover and some rails.
Then you can see a luggage scale on the right which I use to measure the static thrust.
Actually I measure the lift like it was a rocket. I had to secure very strongly the cover to the bin to avoid everything literally jump out from the bin.
Of course I applied some easy calculation to get the thrust from what you read from the scale, it includes the parallelogram rule and the Archimedes’ principle.
Here is the point, one of the test measures I took is below:
So my points are:
- Max thrust I can squeeze is 12Kg not that much, I believe not enough to fly!
- Efficiency is dramatically decreasing as the power increase
- Dry test at the beginning is cool, but after the test I see a severe issue (I think it is due to the leakage)
My next step would be increasing the impeller pitch to 20mm, but I would really appreciate your thoughts.
