Who had predicted that it was better to put the antenna at the small end ? (I think it was WarpTech, and I think he is right)____________Here I show the time fluctuation of the normal stress component at both bases, calculated at the center in both cases (notice that the stress at the center for the Big Base is not the location of the maximum for the Big Base, hence the big difference between the stress at the bases in this picture)

A spacecraft with EM drives in LEO could rapidly accelerate and build up enough velocity to travel to another planet before it is too far out of Earth's gravitational field.So now we have to map Alderson points, and avoid them before we make the jump.
You're getting your SF mixed up. An Alderson point is where you want to be when you fire up the Alderson drive.

Dr. Rodal,Can you give us the sum of the integrals of stress on both bases?Would you like to see some data with the antenna equidistant from the two bases, at the center that is?aero
I need some data:1) Dimensions of your model: (all in meters) I think it is the RFMWGUY model at 2.45 GHz excitation frequencyDbig=Dsmall=Length =

Made from compressed wood fibre. 2 low stiction bearing and a magnetic thrust bearing in the lower end of the rotary shaft. 8 fully visible components. 4 x 12v 6AH SLA batteries, USB Rf gen, Rf amp, Raspberry Pi 2B based real time controller and monitoring system and the EMDrive. Easy to move and set up wherever. No hidden wires, air currents, fishing line, gyro torquers. The people seeing the demo select the indoor site.I then put together the rotary test rig, which they can fully inspect, even xray if they wish.Will then install all the EMDrive system components on the rotary test table and do a few checks to be sure it is all working as expected.Will then step away and invite further inspection.When that is completed, will wirelessly switch on the system and explain how it auto configures itself, finds the best frequency to use and how it starts out at low power (continually testing for the best frequency) and builds up the power to obtain a set acceleration rate, continues acceleration until a set RPM is achieved and then switches off for the next test run, all data recorded. This way I can let it auto search, accelerate, hit target RPM, switch off and repeat the process, while recording heaps of data.It is based on Keep It Simple Stupid (KISS) engineering

@leomillertFor your information, the conversion from inches to meters is: 1 inch = 0.0254 meter.
The NSF-1701 cavity is specified in units of inches.
aero, I ran the simulation for 2 different heights: 5.1 (half of the original) and 2.55 (a quarter of the original).I have all .h5 files ready, but I'm not sure what I should extract.Could you please post all h5totxt commands I should run? I would also be able to create a simple shell script to automate this process, given you provide me with this information.Thanks a lot.

Set the "continuous" switch = 0, and the Gaussian switch = 1, then run the model. You will get from one to six lines of output on the terminal, nothing in the output directory. If Harminv finds nothing, you will get the one header line only. Harminv is set to detect up to 5 resonance frequencies. (after-sources (harminv Ez (vector3 0.05 0.05 0.05) fmeep BW 5)) )If you do get resonance data, please tell us.
