      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!

    "Well, I wanted to find a better way to find and remove a splinter from my finger. After some research we decided to build our own MRI chamber, so I started to do research on it and it turns out that to generate magnetic resonance images you also need so-called Perchlorates, which is a chemical compound also found in the surface of Mars in rather large quantities. So we turned our anechoic chamber into an interplanetary spaceship. And that‘s why we launched a colony on Mars so I could take an MRI of my finger, which altogether is also cheaper than your regular MRI facilitated by the US health care system."

    when ever I see videos of someone who is quite big on youtube trying to make sugar rocket motors, they tend to make a lot of mistakes or just have poor methods. you pretty much nailed everything. only thing i can say is give tips for improvements. you can use a few drops of sodium laureth sulphate/ SLES (the surfactant in shampoo and soaps) to thin the fuel as much as possible. Richard Nakka has a video detailing its use. You may also want to try making a reusable motor out of metal. this will allow you to only need to make fuel grains for each firing. With regards to storage, its best to store it in an air tight container with desiccant to keep the fuel dry otherwise it will pull moisture. the only fuel I've ever used that just does not pull moisture uses erythritol. Another thing is that fuel with iron oxide in it does not store long term, it does something to it that causes the motor to always explode. anyways. good video

    I was in a rocket club when I was in high school sixty years ago. You remind me of the very excellent instructors there. We even had a liquid fuel engine that ran on acetone and compressed air. It was pretty heavy, so it never went very high, but it had a gyro and a gimbaled nozzle. That experience was life changing for me. It didn’t just teach me math, chemistry and rocketry, it taught me confidence, caution, and, above all, how to think. Your site is right up there with the Royal Academy. Thanks so much for this. Really excellent.

    • @Puchacz83

      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.

    • @dougaltolan3017
      @dougaltolan3017 3 года назад +3

      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.

      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…

Flash powder was our standard powder for firecrackers. For larger ones, we slowed down the burn a bit. But I use to tweak the fuel/oxidizer mix, empirically, by examining the residue. Use to get a good thump out of it, when optimized, that would knock over a can a foot away.

    How nice, back in the day we did not have all this fancy modern way of building model rocket motors. Our casings were roll with glued paper bags over maderals. They hardened after a few days, the had to be inspected and sized, plugs and nozzles were made from pounding fire clay and grog with homemade maderals, all our tools had to be made as you could only order the chemicals, scales, and things already available for other uses. It took much longer to do this and then build our own Dinamo meters to test thrust out put, but that only came after hours of testing motors under ground due to many failures. It was fun and I put many years into this until I had a reliable safe motor to use. What you have to now and just order is incredible to me. I wish I could start over, but I have to many medical issues right now. Good video, nice safe shop you have thanks for passing this down to next generations of young people. I still hold a certification in High Power Rockets, mostly as a donation. Although I might attend the LDRS in Black Rock if I am well enough. Thank you.

    8:00 - in all the years I've been watching science and rocket videos on RUclips, you're the first person I've seen who's explained rocket thrust in this manner. Everyone else just talks about Newton, conservation of momentum, reactions, etc. None of this actually explains thrust, this explanation does. I first came across this explanation in a children's book on space flight - I think it was in 1968 or 69 (not a coincidence - everyone, including 7 year olds, were crazy about space flight and rockets back then). The thrust would be the area of the opened door multiplied by the pressure (or pressure differential) in the room. Excellent!

    You obviously don't use a centering ring at the top of the tube when inserting the plunger... but why not? Won't it help line up the cavity with the opening in the nozzle, and wouldn't that be a good thing?

      The combustion chamber concentricity is irrelevant for maintaining optimal thrust alignment, but it has a ton of relevance for the specific impulse of a rocket. A rocket motor is just a pressure vessel, it exerts pressure equally on all sides, so you can poke a hole anywhere in a pressure vessel to get desired results. It doesn't change how the gas vectors out of the nozzle, nor does it become less efficient at getting the gas out. The orifice/nozzle takes care of the directional side of things, so no need to worry about the combustion chamber. Depending on the shape of the combustion chamber, you can change how it erodes and expands during burn, and thus, you can control how you spread that thrust out over a given time. The surface area of this combustion chamber is the sole determining factor in how much propellant is being burned at any given time, and as it burns it gets bigger and thus you increase thrust...unless you shape the combustion chamber in such a way to prevent that from happening. For most hobby rockets, the thrust curve is perfectly fine from a simple CC like the one in the video. But, there are applications where this is not desirable (in cases where you do need engineers doing rocket science to determine what CC you need). For that, they've designed all sorts of CC's that accomplish different thrust curves. An off-center (non-concentric) CC will give you what's called a moon burner, it gives a progressively increasing thrust up to a point and then decreasing thrust before it's spent. A C-slot is very similar to the moon burner. They have some shaped like asterisks that give you maximum thrust in the shortest possible timeframe, some that have two perpendicular cuts that separate the grain into fourths that will give you a very consistently decreasing thrust from max, one that looks like you used a hole saw all the way down the middle which gives you consistently increasing thrust, and lots of others in between. So really, it has everything to do with controlling a given thrust over a given time to suit specific needs, and in this case, I'd imagine he's looking for a non-precise source of high speed gas to power his generator experiment, so he just went with a simple technique that lends itself well to batch consistency.

      @@BrianChristmas The amateur builders that make rockets for their own altitude or speed records often use these types of tricks to accomplish their goals. Basically, if you're restricted to a certain size, say x amount of propellant (meaning you have the same total impulse thrust), then your only options are to change when and how that thrust happens. For max speed, you'll want a fast burning combustion chamber, so a center hole (or asterisk shape) means you'll get a lot of instantaneous thrust and the motor will burn out relatively fast. For max altitude, it's far more efficient to go slower but longer, reducing the amount of aerodynamic forces on the rocket. That's where you'd want an offset moon burner, C-slot, or even and end burner (this is where the chamber doesn't go all the way through, it just burns like a candle from one end to the other). Not a whole lot of thrust at any given time, but it lasts way longer. Arbitrarily speaking, you could have a fast motor last for 2 seconds or a slow motor that lasts for 15 seconds, using the same amount of fuel and still giving the same total impulse. When you add up the thrust over time, a high thrust rocket that lasts a short duration and a low thrust rocket that lasts a long time will both have the same total impulse. It's just all in how you want to design it. Some will go even further and make the grain with multiple chemistries, a slow burn and a fast burn all in one, and then add in a specific combustion chamber to further enhance the thrust curve they want to see over the duration of the flight. If you're going for really high altitude stuff, you'll want a low impulse initially, then transition over to a higher impulse when you get into the really thin atmosphere, and that's where your calculations come into play. How much thrust is needed to get to x altitude, when is the best time to light the fast burn, that sort of thing. It gets more and more complicated the further you dive into it LOL
