Mr. Robelen,

I know you performed some static and dynamic thrust tests on the original EDF-50 with the 20x20X3 blade fan...Have you had a chance to look at the new EDF-50 releases with the newer fan designs? If not, do you plan to do any in the near future? I have access to a wind tunnel here at the university and have been considering doing some tests myself, but I'm not sure I'll end up with any "usable" results. My guess is that the tunnel we have probably doesn't have the resolution to measure the small amounts of thrust. The other concern I have is in the tunnels ability to produce a reliable wind speed at a value comparable to smaller model flight speeds.

Hello Mike,
In a nutshell, no I have not done any more testing on the hext generation EDF. In the course of building a new shop and moving into it, my wind tunnel has been decommissioned for an extended period. Why not have a crack at it yourself? The results may surprise you.
Regards, Dave
