    Shockwave
AI Thread Summary
The discussion centers on methods to reproduce and maintain a shockwave without explosives, leveraging an unlimited electricity supply, such as from a reactor. A notable example is mentioned involving a two-stage air cannon in Europe designed for testing new re-entry vehicle shapes, achieving speeds over Mach 5 for brief durations. The cannon's first stage acts as a booster, creating a secondary shockwave in the second stage. Additionally, an alternative method discussed involves using electricity to compress gas in large tanks, which is then rapidly released through a tube to generate shockwaves for analysis. The conversation reflects a keen interest in innovative technologies for shockwave generation and analysis.

How do u reproduce an maintain a shockwave without the use of explosives.
Having an unlimited supply of electricity ie. straight from a reactor.
Controlling the distance the wave travels ie. 100m

Oh, man... I just saw an awesome unit on Daily Planet a few days ago. It's somewhere in Europe (maybe Germany) and is being used to test a new type of re-entry vehicle that is composed of sharp edges and angles rather than the usual rounded type. It irritates me immensely that I can't remember the details. Basically, it consists of an air cannon a couple of hundred metres long, built in two stages. The entire first section recoils something like 20 cm when it fires. The first stage is a "booster" that skips a gap and sets up a secondary shock in the second stage. It hits the model at something over Mach 5, but lasts only a couple of milliseconds.
I'll see if I can find more information about it.

Please! I'm most interested.

In the meantime, we used to use the electricity to compress gas in large tanks over time, then release the gas over a short duration through a Mach 2+ tube for shock wave analysis.
 
Aww, crap! I just spent a couple of hours trying to find it, without success. Will try again in the next few days.
 
Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice. Only two meetings today, and both went well. The deer that was road killed just down the road two weeks ago is now fully decomposed, so no more smell. Somebody has a spike buck skull for their...
Thread 'In the early days of electricity, they didn't have wall plugs'
Hello scientists, engineers, etc. I have not had any questions for you recently, so have not participated here. I was scanning some material and ran across these 2 ads. I had posted them at another forum, and I thought you may be interested in them as well. History is fascinating stuff! Some houses may have had plugs, but many homes just screwed the appliance into the light socket overhead. Does anyone know when electric wall plugs were in widespread use? 1906 ad DDTJRAC Even big...
