16 ENGINES Multi-Cluster ROCKET With Onboard Camera

I would say this rocket was 90% successful, the last cluster did not ignite correctly (that is why it spiraled). It is a 4x4 multi-cluster rocket. x8 D12-0's and x8 C6-0's!!!

[@napalaprentice]

this video shows perfectly what happens when staging goes wrong.

[@jjthefed]

The best is when you get about a 100 degree turn down from vertical between stages and it begins heading towards the nearby school.

[@moldzillam261]

jjthefed I got a rocket stuck on a school, this was back in 2015 when I was in elementary school. Me and my dad went to the play ground in the back of the school. And normally it would be ok but this time the wind took it and brought it to the roof. So the next day I go up to the office and ask the janitors to go up there (there is a ladder that goes up there, it’s inside) and grab the rocket, they got it for me and at the end of the day I walked out of the school with the rocket in my hand. I got lots of questions about it so I just told them it’s my ballistic missile.

[@2fathomsdeeper]

@@jjthefed Even better when you have RC guidance, and they don't wait for the thrust to end before jumping on the controls! Then it's a tube launched, two stage, H engined, spinny whirly bomb from hell! Once we got that working, we built a laser guided missile, that could hit within 4 feet of the aimpoint at 500 yards. Not too shabby for a couple of 16 yo kids! Those were the fun days!

[@DeputyNordburg]

this video shows why 16 small engines should not replace one larger one.

[@Chris-io2cs]

@@2fathomsdeeper sorry if I sound skeptical but that sounds pretty impressive if true, and like you point out, even more so at the age of 16. Does footage of any of your launches exist? If so you should post it. Sounds interesting. I'm most curious exactly how you implemented the laser guiding system but would like to see what you mean by launch tube as well. You threw a lot of info in there that deserves better explaining haha.

I made a rocket similar to yours with three engines stacked, not clustered. Because of t he weight at the rear, I had these really big fins attached to the engine sections. Anyhow, when we lit it off, the thing was so heavy that the first stage slowly raised it to about fifty feet and then it seemed to slow a little and then the next stage cut in. The difference between the first stage and the second stage was dramatic as the rocket lost about a forth of its weight and it was already moving when that second stage cut it and drove it almost out of sight. At a distance we could see the third stage cut in and it went out of sight for awhile. One thing will stick in my mind was that rocket lighting off that second stage from almost a standstill at about 50 feet off the ground.

I have a friend, back 30 years or so ago, he would fill up short rockets with fireworks guts, and use a first stage D. They were pretty awesome until one he made a little TOO heavy. Made it halfway up the guide wire and just hung there. Never did find the pieces of the launch tower. Pretty sure the public works guys were plenty pissed at the huge dead ring of grass too.

[@brandysigmon9066]

That was the first thing I thought of was the challenger launch, lol

[@georgeskaff9501]

First mistake was to make the fins all the same size.On any staged rocket the booster stage fins have to be bigger than the upper stage to provide the proper balance.The second was to not use lower powered motors in the upper stages, the largest motor should always be used in the booster stage.Those are the basic design elements of multi staging.Thirty plus years of experience has taught me that.

[@marknesselhaus4376]

Much better than I expected. Great job getting the clusters to work that well :-)

[@carpma11]

Wow, I honestly didn't think that would work. Awesome!

[@tstahler5420]

I was a "certified" 10 year old building modified rockets. LOL

[@glennkrieger]

I know from experience that precision in making a rocket is paramount. Cutting, fastening, and aligning everything as best as possible does make a difference. Included in that is the slightly lopsided nose cone, which at the speed the rocket is traveling, will direct airflow over the entire rocket asymmetrically. This creates air eddie currents that will change the effect of the fins have at the bottom, causing the rocket to sway, spin, and waste a lot of the engines energies. Also, the weight of your rocket body is significantly changing your altitude. Using a thin-walled PVC tube of the same diameter would give you hundreds of feet of higher altitude, without compromising strength. After all, with all that work wouldn't you want to go as high as possible?

[@mishapatapovich3996]

See flat earthers, even from a small model rocket you could see that the earth is round

[@CaptainEverythingHumorandMore]

I Agree it is cool. I thought those engines would have went higher but it's ok. Would like to see 16 of them in as one long engine. Good job, nice experiment.

so how exactly do you get "certified" to build these jury rigged rockets?

[@distanttraveler6531]

Obvious that he meant to get certified rather then building rigged rockets...

[@lochinvar00465]

I doubt that he is certified. One look at the rocket told me that. To begin with, the fin sizes are problematic. And staging clusters is not for the faint of heart, as his rocket showed. There should be a positive ignition for all engines of a stage simultaneously at the proper time.

[@paulbarlow8286]

Gerry-rigged. Slang for German. WW2 reference.

[@luisderivas6005]

I agree. One look at the build, and I seriously doubt he has NAR Level 1 certification covering multi-motor rocket models like this one. I don't think this would have passed the requisite safety inspection. Also the certification team is required to observe the flight and render post-flight inspection. However, I think the model would need to use at least one H+ motor, as part of, or in addition to the cluster to be considered certifiable for Level 1. As such this model rides the line as experimental, and not a good design at that.

[@chouseification]

If you're going to correct somebody, at least get it right. He was correct - the phrase is "jury rigged"; not "jerry rigged" or "gerry rigged"... whoever taught you (and all of the other people) the name was wrong.

[@thefreewayoctopus]

@Tech Planet very cool rocket it is too bad some motors didn't ignite or it would've been even better. How high did it go? The locators should tell you.

[@williambresinski6706]

how did you go about solving the simultaneous ignition problem using four engines at a time like that?

[@lochinvar00465]

cross your fingers, of course.

[@willd5105]

It's hard enough to ensure one airborne engine ignites and stages properly. To attempt to parallel and stage each 3 engine cluster in the manner shown resulted in the predictable waste of engines seen when at least one of the second stage engines failed to ignite and the third stage fired so asymmetrically that it failed to separate and whatever fire chain that did make it to the fourth stage poured all it's thrust into the shells of the burned out lower stage engines still attached , but the instability caused by the second stage uneven weight distribution had already spoiled the desired vertical acceleration into a sideways pointing trajectory. It makes more sense to cluster your first stage and use a single second stage engine with numerous redundancies built in to ensure ignition and prompt separation of the first stage.

[@demej00]

How high did it go? How high did you expect it to go?

[@DTORRE-hl7fl]

What material was your cone made out of? @JDRock I am making a rocket very similiar to yours in the video, just struggling to make/find a solution for my nose cone

[@pauls5745]

using a blast deflector is good so you don't leave burn marks on the land. -1 for a sketchy build, but thanks for sharing

[@billybracewell2893]

GREAT design!! I would like to give you a few pointers, NOT critiques. Rocket design takes many forms and sizes. and if PERFECTLY built may still do poorly. But the sport DOES have a few necessary points that need critical attention. 1) a rocket of that size and power can be said to be "nearly" supersonic. THAT changes the airflow greatly. I would do away with the pointy nose cone or modify it with a small teardrop shaped bead. mounted on the point with ITS pointy end out. No more than 1/3rd the diameter of the main body tube. Air at those speeds is more like thin oil or water. It's a "breaker" It causes the thick fast air to jump out and flow neatly down the sides of the "body" of the craft. 2) Pay WAY more attention to you wings. Sweep them like an F-86 Saberjet. Sharpen the leading edges being careful to keep the edges EXACTLY in the center of the edge. Slightly round the trailing edge to reduce "let-off" turbulence. They MUST be exactly in line with each other. And all the exact same size/thickness. 3) shorten your tube some. use a larger tube size with a clear section to mount camera in. The odd shape of the camera pack taped on is causing uneven airflow over your wings. 4) Lastly but somewhat importantly, make sure that after the craft is after final stage separation that the tail is STILL just a tad heavier than the nose. Should see great improvement and a lot more fun!

Would have performed better if you would have used masking tape to attach each stack and then glued them in place. Not all of the motors fired due to that and would have also flown much more stable.
