Sandia Blast Tube - Engineered Explosive Shockwaves in Slow Motion

- Опубліковано 21 вер 2024
- The sandia blast tube facility provides experimental conditions to simulate extreme blast environments. The validation & qualification experimental sciences complex combines large scale environmental test facilities with advanced engineering & diagnostics to solve complex national security problems. Utilizing advanced engineering and modeling, precision shockwaves are bombarded onto test units. Watch in slow motion how a 100 lb. explosive charge is shaped into precise Mach 3 wavefront using high speed photography and synthetic Schlieren wavefront imaging. Advanced data fusion methods show how the wavefront progresses relative to measured pressure data and shockwave physics models.

the calculations are well done i compared with mine so i trust this guys
Sandia - Soundtracks for workouts, gaming and science!
The sound at the start is very much like the sound a blast tube makes when heard from the blast end, every imperfection inside the tube reflects some of the shock front back to the source making a strange roaring sound.
Antimissiles technology.. where it can pass, happens the shock wave. The missiles avoid defended zones, looses time then becomes the target. If not returned to the slammer..
That would be an exciting and fantastic place to work. So much more to learn with new modern analytical technologies available.
videoclipits ikr, I was think the same myself, to be on the forefront of such mind blowing tech.....epic.
Not really lots of down time it takes months to set up the experiment for 5 seconds. then days and weeks of checking the computers and the result. I know I worked there for 36 years. If you ar into computers it would be a good job.
Thanks for your sharing 👍
I assume the shockwave imaging uses a random, but very high contrast pattern and then measures the apparent distortion?
I imagine it is through the distortion of the black dots
A-are you guys always listening this intense music while doing science?
I guarantee it! They also have a cigar smoking buffed up general with ripped off sleeves reiterating the importance of these tests.
@KOB The video was produced by publicity agents, not engineers.
amazing stuff
Are they using an event camera or is just a normal camera and image analysis?
Multi-layered reinforced/backed waves, the original wave would be distorted giving inaccurate data.
In the last clip after the end of the tube the background looks like mountains, and maybe a parking cone..? why is the shock wave “gathering” around the outlines? Or is that part of the tube? It’s hard to tell.
I think they are monitoring the pressure waveform analysis from the frontal wave. The visual distortion is analyzed by pixel changes, and they have a computer program, which records these pixels, simply my changes to the actual video.
As far as how the pressure wave was recorded inside the tube, I’m sure they have a huge string of sensors inside this tube, but likely video as well to measure changes in refracted or reflected pressure gradients. The rest is simply modeled here by a super computer and backwards analyzed.
I’m sure there’s a lot of AI in there as well to calculate the waveform.
One thing I don’t see modeled is the ripple affect, as the pressure did change or modify the shape of the tube along the path.
You can see the primary and secondary pressure waves along the path, which is impressive.
What’s missing is the initial explosive velocity. I’m sure the initial detonation velocity was around 6000-8000 ft per sec, because we are seeing the shockwave at the end of the tube.
/end geek talk.
I don't understand what the difference is between the upper and lower images in the last sequence. I see that the velocity is lower in the bottom one but are they two different experiments?
10Lb charge on the lower image 100Lb charge on the upper image
I think I just found my dream job.
So this thing makes the sounds of a 20 peice orchestra?
When in doubt = C4.
Wouldn't sensors staggered at increasing distances from a central blast be more accurate? Isn't a blast into a tube similar to water speeding through a hose of decreasing diameter? I'm a nurse, not a scientist.
You want decreasing measurement intervals downgradient. The shock wave velocity is decreasing as it moves down the tube.
But why the pressure in the tube is so low after the explosion?
simple physics yo' :[) LoL
it goes "BOOM"!! :[) LoL
Did they just make a huge Voitenko compressor?

My colon after Taco Johns.
I see by attaching a megaphone to a bomb we make it louder
So a sr71 could out run the blast . Good to know lol CV
@TheRageMaker so you can have a taste yo' :[) LoL'''''''''''''''''''
“They” can get away with any crime by calling it :” A question of national secqurity.)
the atomic dijuridoo
What?
"Solving complex national security issues..." Maybe they can solve the national security issue of our wide open southern border in the US 🤔
amen
