Today, I tested a huge 54mm sugar rocket motor and documented the results. Additionally, I demonstrated the relationship between burn time and maximum thrust through a simple presentation.
This is the second video in a series of three. Check back soon for the last video!

Very knowledgeable video. Please provide full details of the motor. For example, how many mm nozzle throt .casing I D how many mm, thank you very much for giving such a beautiful video.

The details of the motor are discussed in this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Sf2Yns8Ixjc.html www.lokiresearch.com/page/Tech_Info Go to the video tab on my page for more information. Please subscribe to the channel.

@@TheRocketeer I watch every video of yours with great interest. I have also been on your channel from the very beginning. I've learned from you how to make rockets. But sadly we don't have all the rocket products available here. So almost everything has to be made by itself. Your videos have helped a lot in this regard. Thank you very much for spending your precious time and replying. Hopeful of getting such an educational video in the future as well.

Please do it with Aluminium / Magnalium in future!!

@TheRocketeer 8 месяцев назад

I like how you think! Experiments with Al/Mg will begin in the spring of next year.

@chrissrocketryandmore 8 месяцев назад

That is awesome. That was a great job. I look forward to seeing that in a rocket.

@TheRocketeer 8 месяцев назад

You and me both!

Very nice! I'm hoping to have my "Dan Pollino" K motor coming soon as well. How long were each of the grains for this one and what was the core size? I'm really interested to see what rocket you're gonna lift off with this monster.

@TheRocketeer 7 месяцев назад

I used 5x grains with a 5/8 core, 1x with a 3/4 core and the last was 1x at 7/8. The larger diameter grains are used to keep erosive burning in check. Each grain had a 1/4 space between them. I may reduce the gap to 1/8" in the next motor. I am going to put this monster in a 4" fiberglass rocket to reach a mile. I always wanted to see a Pollino "K class" motor!

What are you using for data collection and software? Load cell? Pressure data?

@TheRocketeer 8 месяцев назад

My data collection system begins with 5 years of experience making sugar motors and BATES grains from D to K class. Then I used BurnSim with a profile provided by Finicky on The Rocketry Forum that I have found to be quite accurate for designing sorbitol sugar motors, I am CaptHaywire on the forum. I have a digital thrust stand built and designed by Boris Dureau that will measure both pressure and thrust. I will feature the design next spring in a video. Please subscribe to the channel for more information.

@TheRocketeer i was curious about what the actual hardware and software was. If you're getting both pressure and load cell data. I've been making motors for the last 20 years.. Have made motors from G to P sizes up to 6 inch hardware. Have plans currently for an 8 inch Q. I do APCP. Over the years, I have used pressure data via transducers, load cells ,DataQ systems, and software. Plus, some other proprietary systems. Have been using Burnsim for quite a long time. Just recently started using the Altus Metrum Easy motor as an addition.

@TheRocketeer 8 месяцев назад

Yes, Easy Motor is on my list to try, I enjoy flying more than motor testing.. I have access to a KitchenAid mixer, vacuum motor, stainless steel bowl etc. There are no channels devoted to APCP and I don't live out west so that presents a problem for me and others who may be interested in the craft. Thanks for stopping by!@@VikingRocketeer
