Thanks for sharing the experience. few question I may : 1- what do you think where the most expenses go to to in this kind of projects ? 2- what is the comparison of this motor to the sugar one (in term of power) ?
For my rocket motor "SN2," the most expensive components are the custom CNC-machined nozzle and bulkhead. While there are certainly cheaper ways to build a rocket motor, my main goal is to create a fully reusable high-power motor! In this video and others, I am using a sugar-based propellant known as "Rocket Candy." I've optimized the formulation specifically for my motor to ensure maximum efficiency!
Hi bro I want to make a sugar rocket that it is like 15mm in diameter and like 2pm long, I want it to just burn for one second and also generate 100N of force, could you pls help me if this is possible and more info I want it to stop a 3kg car from 120kmh to 0kmh
I’d recommend starting with OpenMotor. OpenMotor is a great tool that allows you to simulate the rocket’s thrust and other parameters. It can help you determine if your design will produce the required 100N of force in the given size and burn time. Once you run the simulations, you can adjust the fuel grain design or nozzle parameters to achieve the desired performance.
@@seitzfamily070 For this test I am using 65/35 KNSB with 1.25 %Iron Oxide and 0.2% SLS! The formula specs for KNSB should come pre-installed on Openmotor!
@seitzfamily070 My casing is a 0.071-inch wall diameter aluminum pipe I sourced from Amazon. I drill the necessary holes to attach the bulkhead and nozzle. Aside from the cardboard tubes I use to cast the propellant, the casing has no liner. Despite this, I’ve never experienced issues with the sugar propellant melting or distorting the casing, even after 14 successful motor tests.
@@undead7534 I’ll be sharing the results in an upcoming video! I’m testing the propellant today to ensure it performs as expected before showcasing it. This formula is slightly modified from the ones I’ve used previously.
I'm about to start this job. I have 3 equipment left to buy. Electronic Scale. Hotplate. Far infrared thermometer. Can you send me the link of the products you use? Is there any advice you can give me? What should I pay attention to when buying these? Thank you for your reply in advance.
@@Doganay14 When casting propellant, always prioritize safety. I’m using a generic hot plate and temperature sensor purchased from Amazon, but ensure your equipment is reliable and suited for the task. Obtain your chemicals from a reputable supplier and verify they are of high purity. When pouring the propellant, be sure to tap it thoroughly to eliminate air bubbles, as this step is crucial for achieving consistent and safe results!
@@Ericlfimate The finocyl ‘Y’ shape in my rocket grain increases the burn surface area for a boost in initial thrust, but since it’s only 1.5 inches deep, it mainly affects the startup phase!
@AeroPropulsions will not that leads to uneven fuel burnt? Even with a normal (without y) the place where we put the igniter burnt faster because that's the first place it burnt. If it's for initial boost, how i used to do is i make the igniter myself, and cover the igniter with the same fuel, the size of the rode and tightly fitted inside. That way the moment i ignite it, the fuel attach to the igniter become a small boost without causing uneven fuel burning.

Needed this
Very helpful brother from 🇮🇳
Happy I helped!

you could try add a small amount of aluminium powder like 5% additional would be interesting to see the difference
I tried it for the previous test fire, but it didn’t yield the results I was hoping for.
@@AeroPropulsions strange have you also tried using CuO?
Cool
Hacksaw a slot down the side of your bolt to eliminate the suction problem
Will do, thank you!
🤩

I'm currently running a large perchlorate cell for making ammonium perchlorate for APCP
Very cool! Would love to do something like that someday.
Hey! I would love a video on your propellant. And maybe it's specs for open motor

@@AeroPropulsions 😭
Just figured that out
I attempted to calc all of it
@@AeroPropulsions I have two more questions, if that's ok.
1. Where do you get your cases
2. What do you use for your liner
@seitzfamily070 My casing is a 0.071-inch wall diameter aluminum pipe I sourced from Amazon. I drill the necessary holes to attach the bulkhead and nozzle. Aside from the cardboard tubes I use to cast the propellant, the casing has no liner.

@@AeroPropulsions thanks!
Have you try make sugar rocket with a press or hammer, instead of melting
@@Wang_1029Yes I have! I started with half-inch grains, pressing the rocket fuel and coring it afterward, but I’ve found that melting is far easier!
Thx for the info. I was planning on buy the tool for press.
@@Wang_1029 No problem. Hope everything goes well!
NICE WORK BRO can u please write the ingredients u use in the description
@@undead7534 I’ll be sharing the results in an upcoming video! I’m testing the propellant today to ensure it performs as expected before showcasing it. This formula is slightly modified from the ones I’ve used previously.
@@AeroPropulsions ok thank u, im hyped till u post it
What's the dimension of the grain?
I'm about to start this job. I have 3 equipment left to buy.
Electronic Scale.
Hotplate.
Far infrared thermometer.
Can you send me the link of the products you use?
Is there any advice you can give me? What should I pay attention to when buying these? Thank you for your reply in advance.

@@AeroPropulsions Thanks for the heart and reply.
@ No problem! Hope all goes well!
4:53 you're motor have "Y" on one side. Why is there a "Y" what is the purpose? Can you explain it to me in detail?

Ingredients measurements please
26% Milled KNO3, 39% Granular KNO3, 35% Sorbitol. You can also add 1-3% Red Iron Oxide. Scale to your need!
Thanks
