At mine, high school, in the 80's & early 90's they taught some of these ways chems can be used. No more, just that America is an evil country & it should be hated. Very anti-commie back then too. Now they're top professors at many universities & even sooner. Not too pleased or optimistic about were we'll end up if this socialism/communism popularity continues and isn't countered with how America is quite awesome . But these schools, constantly teaching our own children to hate America and only look at the bad things that happened. Not gonna be a recipe for survival

I had such a teacher back in HS. I don't remember the reason, but in class he created a little NI₃ to spread out in the hallway. You know, that fun stuff made by soaking iodine crystals with household ammonia! DON'T try this at home if you know nothing about it. He disappeared from the school's faculty the following year, and a couple of years later I was working as a grocery bagger in the local market while he was a shelf stocker! The owner of the market sat on the school board that probably had something to do with deciding his career change!

And same for the video that I had seen in the hour it appeared and loved the progress and evolution in all details. Spend the whole video to make sure to understand the big points. But a lot of people will run in trouble here due to the chemistry if you order too much and online cause what is great to power a rocket is also great for a bomb and we had a swedish guy buying ingredients online due to his hope swedish restrictions would end at the border.

@@ncdave789 different type of motor.also thats the worst way to make a rocket motor

using fuse to ignite 'and run' from any experimental rocket motor is flirting with danger and how many are injured/killed

@@mojaverockets I'd be tempted to make a core alignment jig. The reliability of these engines is contingent on many things. One of which is the reproducibility of the core. Simply jamming it into the molten mix will, eventually lead to a CATO of the engine at worst, at best unreliable motors. Also, it would have been nice to weigh the test composites to at least increase the chances of comparing apples to apples :) Anyway, always enjoy your work. Stay Safe and Stay Well.

@@ncdave789 just because your big on KZfaq doesn’t make what your doing safe

Na, let's start simple by going with a giro based internal guidance system, going full V2 stile. XD

Can I use a gyroscope from a plane?

igniting any experimental motor with a fuse and run is probably one of the most dangerous things that can be done in rocketry and has resulted in numerous injuries and deaths.

It's fairly easy to get it outside of commercial use, but most suppliers still want see some credentials just to be reasonably certain that you're not some random nut job that will cause another round of regulatory scrutiny. I know a chemist that got a visit from the FBI for ordering oxidizers, and it was probably just a routine audit and their name fell out of the hat, and nothing happened. But they are watching and companies do want to protect themselves from liability.

man has good taste just like his channel

*True*

It is and it is not rocket science. it is because we are talking rockets it is not in the sense that you use "rocket science" to describe something really hard.

Don't get me wrong, I still like a good explosion, just not too close. Or with too much flyrock or shrapnel, fleshettes or like that. You know, were talking recreational use.

I suppose it could be achieved, if You would have signigicant diameter of the rocket (quite big is necessary) and then wou would use some internal tube every time in different diameter to our the next layer of the fuel. PRocess would take few days, but it's achieveable.

That would work but is not relevant to a motor that could (easily) be built that way. A serious issue with the plain hole through the middle is that as it burns the surface area increases, increasing gas production and therefore thrust. The "simple" way to get round this is to use a star shaped hole, the surface area remains constant, but would make layered manufacture very very tricky. Having said that though, a layered approach would be another solution. One construction technique could be like dipping candles. Each dip in hot wax adds a thin layer.

The use of layered propellants with different burn rates and ISP is used in solid rocket motors industry, generally referred to as dual thrust.

Layered propellants and combustion chamber designs are what the big boys use to achieve necessary thrust curves.

He put all his points in speech/int

rockets are just an excuse to play with Magnetohydrodynamics. I like it.

Welcome!

People often underestimate just how much energy is stored in regular Sucrose. Your typical kilogram bag of sugar contains 17 mega-joules of molecular energy. That’s a little over four times the energy stored in a kilogram block of pure TNT… Even if Sugar doesn’t burn when you put a flame to it, that obviously doesn’t mean that the retained energy can’t be utilized. It just needs an oxygen-rich environment. Like when mixed with an oxidizing agent or mixture of oxidizers with a decomposition catalyst…

@@gabriel_martz1470 Oh, so we’re gonna talk about the TR-3B now?

"... and lube" 🤣🤣🤣

@@ExplosivesLaboratory I don't know what that is. So yes please 😂

It was. It may be that the extra stress at throttle up was the last straw and the SRB gave way, but it was not the throttled engines themselves that blew.

I was not expecting you to be intrested in rocket science, not gonna lie

Wind shear aloft was also a factor. An in situ plug of debris from exhaust particles and burnt seal material formed in the joint after ignition, which kept the joint from cracking wide open right away. Otherwise Challenger and her crew would have been destroyed right on the pad. When Challenger entered that unusually strong wind shear level (coincidentally near max-q), the flexing of the booster jarred the plug loose. Engine throttle up was the icing on the cake. Once that happened the exhaust gases were essentially a thermite blowtorch flame in a supersonic slipstream; it cut the aft booster attach point, and the aft dome of the external tank, causing liquid hydrogen to stream out. It wasn't long before the bottom of the tank opened up circumferentially like a zipper, and that was all she wrote. Aero forces then broke the whole stack up. All because of something as simple as rubber seals failing in cold temperatures. I hope that answers your question!

@@TechIngredients saw a video on this. The seal is to keep pressure inside. The way the srbs are made came into play. They were made in sections and joined at the ends using a y shaped edge with an o ring inside to keep pressure on the bottom of the next section, along with some pins. When you watch a video of the challenger taking off you can see some wiggling at the bottom of the srbs. That combined with a cold o ring and the design allowed pressure to leak out. Specifically when it flexed, the o rings should've expanded to keep pressure on the two sections of the srb but didn't and a side of the y connector flexed to let pressure out. Which just happened to be hot and just tore the thing apart. Scott manley has a great video on it. Forgot the name though sorry about that.

@@ethansmith5560 There wast least one other booster which had one of the pair of O rings fail. The outer of the two O rings was all that stopped it from failing in the same way as Challenger. Like many disasters, it was not caused by just one failed component; it happened because of a concatenation of several circumstances, including cold weather, two failed O rings, failure at exactly the right point for hot gas to be ejected onto the fuel tank, wind shear at Max Q and sloppy manufacturing and safety testing techniques, compounded by managers not listening to the dire warnings which were given by engineers. In some ways, you can say that they were tragically unlucky on that occasion, but that doesn't give the whole picture. The Columbia disaster was another example of circumstances coming together to create a tragedy. All previous successful flights had had debris falling off the craft at launch, but the crews of those missions were lucky, because it had always failed to dislodge the vital heat shield tiles which completed the events and omissions which led up to the disaster.

"I don't know... yet"
