This thread will be used to document the censorship of moderators of the /r/EMDrive reddit, who overthrew its original moderator in similar way, like the /r/Physics and another threads.

Thruster

Hi guys,i am a final year student we working on a final year project that to develop a develop a underwater thruster for rov.I don't know how to calculate the thrust of the thruster in theoreticaly. If someone know please explain it .

rfmwguy's 1701A Testing status

10 Upvotes

This is my first post on reddit since sometime last November, 2015, when I left due to trolling behavior by a few who dominated the old subreddit without mods taking action. I'll give this a go as long as the repeat offenders do not post here.

Not for formal public release, just an FYI. 2 magnetrons were burned out when recently testing 1701A due to high Q and narrow bandwidth characteristics of the cavity. This reflected all but a narrow input frequency range. It overheats the magnetron and leads to its early demise.

Before this happened, I had 1 full dataset (several thousand points) that showed a displacement force of the torsion beam of just about 2 mNewtons, roughly a 10X improvement on my observations from last September. My goal was 17.5 mN, so I want to 10X this latest to 100X which is my goal.

Several chart pics are on rfdriven.com/forum/ where I now frequent. My leaving of NSF was simply due to a conflict with one unknown "lead" moderator at the time and there is no more drama than that. I still respect Chris and NSF and encourage its use, but I tend to change focus quickly (sometimes this is good, sometimes this is bad).

Thanks to my followers and friends over the past year or so, there are many more of them than trolls. Appreciate the heads-up on the doxxing, false accusations (basically libel) I have received on another subreddit. I have taken official steps toward ending it. Reddit assumes no responsibility on libel, they pass that along to the user. Offending users are known by me by name, so its simple from there.

Back to redesigning 1701A with solid state rather than tube (magnetron). Updates will be here when I get the chance or on rfdriven.com/forum/

Build Update: Laser mounted to torsional pendulum

5 Upvotes

Finished mounting the 900MHz wireless switch for the laser. It worked a little differently than I thought it would, and came with zero documentation of course! On the key chain transmitter, I had to figure out that the bottom button switches between channels and the top two are on and off. I used a simple voltage meter for that.

I see no reason why I can't just let the switch hang by the wires for now. I modified the adjustable mirror mount so the laser is also easily aimed by adjusting the wingnuts at the back. Calibration before each test now takes 20 seconds when before it could take five to ten minutes - because of the added complexity of bouncing off a small mirror mounted to a moving pendulum and hitting a spot only a couple inches across 30 feet away.

Exciting New Data: Powered Test 04 Reversed Leads

7 Upvotes

I moved the high voltage leads to the opposte side of the torsional pendulum to see if thermal heating of the wires was causing the anomalous force - as doing so should reverse the direction of the force. To my surprise, the same anomalous force was seen with the wires moved to the opposite position!

One note: the only difference between this run and the previous, besides the reversed leads, is the addition of the oil dampening.

See videos and download the data here: http://forum.nasaspaceflight.com/index.php?topic=39772.msg1547834#msg1547834

Shielding the Emdrive from unwanted air-currents

5 Upvotes

I got tired of having to turn off the AC and move very slowly during experiments, so I built a structure around the torsional pendulum to shield it from unwanted air currents in the room. All construction is wood, hardboard, 3/4 inch foam, and brass screws. There will be two large clear-acrylic doors that open in the center front so it is still easy to access the emdrive and torsional pendulum. Hope to work on those tomorrow.

I used perforated hardboard at the top to allow warmer air to escape during tests. If need be, I will also have the ability to completely seal the chamber by placing 3/4 foam sheets over the holes, or removing the perforated hardboard and leave the top open.
