SCREAMING Shotgun Slug - Rocket Nozzle Experiment

Saar sent us some de Laval nozzle pro-jo's to test out in this video. What will happen if just the nozzle is driven through the air? Knowing from past tests about how the bow shockwave prevents airflow through something like this - I knew they had to be launched at much slower speeds. We learn a lot about subsonic and transonic speeds and their effects in this test.

They really just need to make a video where they show an invention that launches these projectiles and just mute out the sound of the gun shot. Like make some thing like a giant potato cannon wrapped with wires and circuit boards, a burst disc at the front of a vacuumed barrel and then say this is our launcher. It's OK if everyone on the channel can tell if it is fake as long as it tricks the censor person. Also go full out on the pretending it is a rail-gun type thing with no "rail GUN" giggle giggle slip ups. then they just need to either blank out the sound of the gun or even better replace the sound of the gun shooting with some cheesy sound effect like someone flicking a thin piece of spring steel with some charging capacitors overlayed on it. if you use a few sound effects at once to create a cool sound they might believe it but I would at least start by muting out the sound during the gunshot. The more you obscure it the better. bring a piece of pvc pipe with you and strap it to the end of the shooting table or shoot the slug through a much bigger wide open one and make it even more believable that it's a giant potato-rail-vacuum launcher, not gun. actually eliminate all uses of the word gun from he videos.

[@xjet]

It's pretty clear that even at subsonic speeds the flow of air through the throat of the DLV nozzle is choking for several reasons -- one of the biggest would likely be the creation of a ring vortex due to the sharp transition from convergent cone to straight section. In my work with pulsejets I found that a sharp edge promotes a ring vortex that effectively reduces the throat area of a tube by a huge amount. What's needed here is a smooth (curved) transition so as to avoid the flow separation that promotes the forming of a ring vortex. This is also why you'll notice that jet engines have a bell-mouth intake rather than just a sharp edge at the front. Without the smooth curved intake, the ring-vortex would severely choke the flow of air oing into the engine.

Nice work Taofledermaus Crew! As to your comment at the end of the video, I have learned something. Your experiments really helped me to better understand and visualize the issues the U.S. Aircraft Manufacturers and Air Force Pilots were having with compressibility. As you know, it caused an aircraft's control surfaces to be useless when the aircraft was flown in the transonic range and caused the death of many pilots. Once they figured out that swept wings were the answer the next issue was; how to get the air into the jet engines at high transonic and supersonic speeds, and once it was in the engine, how to slow down that airflow to a subsonic speed in the engine so that shock waves don't form inside the engine and tear it into pieces. Your experiment in this video really helped me to visualize what exactly is happening when an object approaches the speed of sound, thank you!

[@taofledermaus]

thanks John!

[@DrCzew]

Doing this will make it very difficult to get supersonic exit flow. Even if you do obtain choked flow at the throat, you’d need substantial back pressure that would be many times that of atmospheric to push a shock out of the nozzle exit and get supersonic exit flow.

I'd be interested in seeing how this proje- err, accelerator, handles the transition from supersonic to subsonic.

Next step: Put this ring thing around a central tube, that resides in a larger, outer tube. The central tube has a few tiny holes to vent some of the 'steam' into a cavity behind the flying ring. The middle tube propels an 'aerodynamic cone' to create a low-pressure zone in the path of the ring. Pressure transferred from the inner tube to the outer tube propels the flying ring into the void that is cleared by the faster cone. Anticipated result: *SCIENCE*

[@Hirosjimma]

And fit it in a 12ga diameter, and make it able to withstand a couple hundred g on launch

[@heyarno]

@@Hirosjimma My thought is to make it from 2 main parts. A outer cylinder with a sealing lip and the inner part from rather thin titanium. The cavity between both will be the fuel tank. And a smaller mass that seals the fuel injector and rushes down the tank when accelerated to displace a priming amount of fuel into the mixer/burn chamber. For ignition, I plan to use the flex of the upper portion of the inner part. It will set the heavier than fuel component free and mix it thanks to the high acceleration on launch. The mix will ignite on air contact. So I don't think there will be problems with the acceleration or size. The geometry works in our favour against the main forces. I just need to figure out where to put the air ports to have neutral pressure when equalising the tanks pressure for the fuel that is used up. I guess I'll make a parametric 3d model to be able to change these positions easy and make some models filled with water. Then see how they behave in a strong air blast. Sadly I have no high speed camera. But then this is supposed to be a fun exercise. Oh well I guess I'll have to provide doodles for any of this to make sense. For now it's bed time.
