The way you're able to blend the CG and real footage is amazing!!

For all of the great advancements that Space X, ULA, and other companies are coming out with, I still love watching and hearing the raw power of the SRBs and RS25 engines. Yes, they may not be the most modern but even today they are still amazing for the amount of power they generate.

That was 100% badass.

This is by far your best work to date. Not only did you incorporate real world footage seamlessly with a 3D model, you also showed the violent jet of flame that resides within the booster during firing. I am in awe, good sir!

The real footage and cgi is SEEMLESS

I've always been impressed by the way SRBs burn outwards from a central tunnel through the solid fuel, which keeps the heat away from the containing shell until the last possible moment. Clever!

Scott Manley release a video about solid rocket booster at the same day as Hazegrayart? *PERFECT*

Never knew how solid boosters worked on the inside. I always thought they worked like fireworks, it ignites from the bottom to the top.

My mom will still put hand in that and will be like: okay, still ain't ready for cooking,

We need to know the identity of the man behind the curtain. This Wizard deserves the credit.

Your animation makes it easy to see that even the SRB gets lighter during launch. As the fuel material is burned away that thing is getting MUCH lighter, making everything accelerate even faster. Wow thank you.

Say Fred: did you remember to check the O rings?

One week before test, Mother rabbit: "This looks like a nice place to raise a family."

Keep up the good work. Loving these internal visuals.

Your renderings are always amazing. Very informative!

Close to being accurate. The top half of the top segment, (where the pyro ignitor is,) has an 11 point star shaped bore, to one, aid in rapid ignition of all fuel grains by quickly producing pressurized hot gas due to the 11 point star bore’s higher surface area, two, to provide more thrust at liftoff than an all cylindrical, or truncated cone, bore would, and three, to burn away quickly leaving a void in the top of the top SRB segment that reduces chamber pressure slightly, and thus thrust, to aid with safe Max-Q transition. Basically an SRB version of throttling, like the RS-25 main engines are done, before Max-Q. The thrust curve looks kind of like a mountain. It rises very quickly, almost straight up and down, to about 2.8 million lbf, it slows building for a short time, topping at around 3.2 million lbf, it starts tailing off some down after 50 seconds to around 2.3 mil lbf, roughly 2/3’s the original thrust, that builds a bit back up to a second peak at 2.55 mil lbf, that then tails off gradually to 1.6 mil lbf, until approaching fuel exhaustion, where it drops downward quickly, and chamber pressure dropout automatically activates the SRB Sep system. This shows a representation of that upper, 11 point star bore, but doesn’t show it burn away quickly, leaving the thrust reducing void. Also the bore gasses would be much brighter, but for an animated demonstration this is just fine. 11 point star issue aside, cool demonstration. For those interested, the SRB propellant is APCP, Ammonium Perchlorate Composite Propellant. It consists of 69.6% (by weight) Ammonium perchlorate (oxidizer,) 16% atomized aluminum powder (primary fuel,) 0.4% black iron oxide (burn rate catalyst, and an opacifier that makes the fuel opaque to infrared heat radiation, that would otherwise overheat the fuel yet to be burned, and cause an explosion,) 12.04% PBAN polybutadiene acrylonitrile (composite binder and secondary fuel,) and finally 1.96% epoxy curing agent.

So that's what the inside looks like 😯 Cool

Perfectly timed with Scott Manley’s video

Very cool! Loved the cutaway view of the internals!

Very well done, Haze. The CGI is amazing.

Super universe challenge: Stand at the exhaust region of the rocket booster.

Some of this is real right? Like it isnt all CG? otherwise that smoke plume is amazing

That was freaking awesome, more please!

Keep the great work up mate! Wish you were around when I was in hs 30 years ago

Wow!! Thats pretty cool!

What am I even looking at? It looks like mastery over hell.

this is easily the most underrated channel

I give up. I can't tell what's real or CGI on this channel anymore. Awesome job.

This editing is magic at this point!

They didn’t test the engine. They just wanted to turn earth to prevent night from coming

Awesome animation of the grain burn back!

Just brilliant!! Well done and thank you!!

A suggestion: do the fate of the jettisoned Saturn 5 stages. Nobody ever had images of those, much less videos of them crashing or reentering.

It is all about controlling the back pressure. Engineering is awesome 🤘

Great job !... Bravo to the responsible of the animation... :-) From Brussels, with Love...

Awesome CG! The lighting gave it away and the fire. But still❤️😍

Me : *eat deadly spicy* Me in bathroom:

my laptop when I turn it on 0:07 When I click chrome 0:12

Your motion tracking is completely flawless

Excellent computer video composite modelling to the real event. Like you replaced a section of the walls and plasticized propellant with a magic forcefield

Early. Keep up with the high quality visuals. also do you plan on expanding into the aircraft sectors? Will be awesome to see some 3d renders for the X-planes series

Brilliant! But also a little weird when the casing closed up at the end!

My respect for SRB has moved upto next level.

On model rockets sized C and D you can drill a small hole thru the center of the propellant but not out the top. It will give it more initial thrust but cut duration down. Just dont go to far or it will burn thru the to and stage before it completely burns out.

NASA to EPA " Nothing to see here..."

I would like to cook a sausage on a very long stick.

That's quite clever....well done!

1 word? Beautiful.

when you eat taco bell :

I don't think that's an accurate representation of what's going on inside a solid fuel booster.

QUESTION. As the booster burns from the inside out as the internal surface area increases dose the thrust also increase?

Another satisfying video

What if it gets launched horizontally and finally leaves the earth tangentially

🤔🤔🤔

Awesome video!!!

Thanks bro I know now what's happening inside

This is exactly what my S19 bitcoin miner looks like when I overclock it by 1%.

Flat earth logic: NASA is doing all these, spending billions of dollars on experiments and CGI to trick them into believing that earth is an oblate spheroid.

The amount of pressure that Rig must whitstand is freaking insane..

Looks so real, I didn't know it was cgi and was wondering what type of glass that can contain such extreme heat and pressure lol

As a solid propellant ballistician I'll tell you this graphic is meaningless. The propellant grains (as in the case of this booster, Titan IV, Ariane 5) evolve gas locally and as that mass is added moving down the port velocity increases. At the head end of the motor gas velocity is zero; stagnation pressure and static pressure is equal. For most of the grain incompressible flow (Bernoulli) is sufficient for the core velocity; compressibility only arises in the latter portion of manner motors and into the nozzle. Combustion stability is a boundary layer effect and the turbulence shown in this picture would not be so dynamic. This is not a CFD simulation but a "pretty" animation. It may convey a concept but it is a poor match for real behavior. ROCSTAR (originally from the University of Illinois, Urbana) was the only code that I know that could give you the properly flow field. Because you don't see the grain represented is why you know it's a graphic interpretation

A completly unrealistic, inaccurate and made up image of what actually happens during a solid fuel burn

is the propellant in another chamber burning and the flames are channeled down the centre and out? it looks here like all the flames are coming from the nose

Is this locate north part of Utah? I saw when I drove I-15 to north.

Retired physics professor , Not an accurate representation of the actual combustion process!

That is NOT how it works. How can you burn solid rocket fuel THROUGH solid rocket fuel? Duh

Plot twist : this is actually a demonstration of the strength of the structure and foundation which hold the rocket in place.

:-))))) welldone, as usual !

I never seen anything like this! I grew up around rockets all my life untill I was 17 and went off to war. My father was a designer for AeroJet General in Sacramento (Rancho Cordova) CA and his brother was a chemist for McDonnell Douglas also in the same location he helped to develop the solid rocker fuel in the 60's and 70's. You always could tell they were testing a Saturn motor because we were less than 7 miles from the test stand and in those days there was nothing much more than a lot of nothing between us. I can not count the number of broken windows we had. There was always Cordova Glass in the area replacing glass. Any no one had to pay for it. Guess you could call it a company benefit. Great job on the video, I only wish I could have seen it all the way to the end without them closing the clam doors back up. I would like to have known how much longer the combustion went of after the fuel "ran out"

Thank you...❤

Very cool blend of actual and CGI

wow how did you make those videos? I wish i can make some saturn and n-1 comparison with that. or can you make us one plz?

Wow really Kool thank you so much love rocket

always surprised at how few subscribers this channel has.

so the booster supplies the most thrust just before shutting down?

Wow 😳 what a thrust!!!

Pretty cool anamation.

Awesome video.

How do you keep something like that from melting?

When your boss tells you that you can head home when the sun sets and you aim it westward.

This machine i.e. SRB gives instant feedback, no warming up to get started!

The videos of Hazegrayart I press the button liked before watching it, because I know it is always something fantastic.

Everyone gangsta until the bolts loosen.

Question… is the fuel being burnt towards the end of its operation weaker than when it starts? Otherwise the increased surface area would cause a much higher thrust output, would probably destroy the rocket

I'm curious if the hill they are intentionally firing into provides a benefit that out ways its discharge.

Do these ones also come with the FLDS o-rings?

The burning effect reminded me of the burning in The Falling Sand flash game

As a refinement, it would explain the ignition better if you showed the operation of the flame thrower at the top of the booster that sprays flame down the core of the propellant and then, I assume, stops once the main burn is established. Therefore there would be no flame at the reduced diameter top section.

Strong energy!

Good. Now edit in Slim Pickens as Major Kong sitting on the booster, waving his cowboy hat around going "Yieeeeeee-haaaaaa!" :-D

Giving new meaning to "scorched earth".

And a great way to stay in shape

Why does this man not have 10m subscribers?

Notice how the ground was smoking 50 feet to the left away from the blast...really cool....

Which kind of fuiel used in rocket engine? This is awesome

Nice CG bro

Brilliant I can't imagine

Why doesn't the nozzle melt on SRB's?

Amazing work! Love the blending of cgi

Are they trying to slow down or speed up earth rotation there ?
