General physics and advanced plasma research 1935-45

The claims are not extraordinary. Ordinary proof will do. A careful reading of B.I.O.S. Reports from the immediate post-war period yields proof by individuals who were qualified to assess what they found.

Reports of devices who's capabilities we can't duplicate today and which are not explicable by modern science certainly are extraordinary at best.

This site was kind enough to scan/archive the "Intelligence Reporter". This article is from May 1946.
Kammler would have been the administrator of this type of project in 1944-45. What interests me is the phrase "Recoil is negligible," . This text is from 1946, It is very controversial in the physics community [even today] as railgun experiments have broken f=ma .

The site has many axis weapons manuals translated to English.

Hello,
I'm absolutely no expert in this, but maby the following can be of use.

In the (no lnger existing) german magazine "Waffen-Revue", a series of articles was published on the development of a 4-cm electrical anti-aircraft gun.

They published a number of german documents, one of which was 'Design for an electrical 4-cm AA gun' from late january 1945. It was signed by Dr Joachim Hänsler, director of the 'Gesellschaft für Gerätebau m.b.H.' in Klais, Upper Bavaria.

The drawings from the 1946 US intelligence report are apparently taken from this german report. The design aims for a 4-cm calibre rail-gun design with an initial "muzzle"-velocity of 3000 m/s.

An earlier report dated january 18th 1945 mentions experiments with 10,8 gramme projectiles achieving an initial velocity of 1080 m/s using currents of 21000 A.
Experiments with 2-m and 4-m barrels were planned to increase the initial velocity.

The report on the 4-cm design mentions also that the generator assembly would probably weigh some 37,5t, concluding that: "the first operational guns might already be transportable".

I include some pages: two with drawings, and one with a diagram showing the results of experiments and the planned future results.

A further report on a meeting september 29-30 1944 mentions some German patents in this field: 374 950, 376 391 and 371 851, by a frenchman Fouchon-Vileplée.

Hope this helps,

Marcel

They most certainly have not. EM guns (both rail and coil ) are not exempt from the f=ma relationship although at extreme vellocities relativistic corrections must be made.

That's almsot 6KJ. One of the main practical problems here is getting the gun to survive. Railguns tend to need new barrels after a few shots (in many cases few = 1). Rate of fire is also a problem and aserious one for an AA weapon.

Marcel, Could you scan the entire series of articles? If not, thanks anyway.

The other pages are coming. Thanks to Marcel.

I assume the Japanese device is similar. This is pretty much the entire design, it could be duplicated with this data thanks to Marcel.

Very nice to have all of the data, fyi the current velocities are around 12km/s.

It has been almost ten years looking at this, now I am sure that our 'popular' physics is bogus.
The "relativistic correction" is a product of propaganda and herd-like religious belief. Thank you Dr. Graneau

A rather wierd and completely unsupported opinion. In particular the "relativistic correction" has nothing to do with propaganda or "herd-like religious belief", it's a direct consequence of physics as we understand it and it has been confirmed by experimentation. If you have any evidence to the contrary PLS post it otherwise I believe this board discourages opinion only posts especially those which contrevene reality.

See ISBN 981-02-2284 but I'll let you find the page with the proof equation/experiment. Any undergrad can set up the test.

No lab experiment exists which proves relativistic electrodynamics, only claims with algebra errors and 'fudge factors'. Check for yourself.

Best Regards !

I'm familiar with the problem. Admittedly I haven't done the math in a fair number of years but I have done it. There have indeed been experiments that clearly validate relativistic corrections are required when velocities exceed about .1c. An ISBN is hardly a decent source by the way at least by the conventions of this board. Furthermore a little quick googleing doesn't enspire any confidence in the book you mention.

And obvious example is the GPS, it requires special and general relativity corrections all the time, as it would be unusable without them, after a few hours the accumulated positional error would be a kilometer or two.

An earlier report dated january 18th 1945 mentions experiments with 10,8 gramme projectiles achieving an initial velocity of 1080 m/s using currents of 21000 A.
Experiments with 2-m and 4-m barrels were planned to increase the initial velocity.

So we have a 40 ton transportable Rube Goldberg contraption here, with its capabilities comparable to a M1 Garand, that was firing a heavier round anyway....
