POWER!!!!!!!!!!!!

I saw shockdiamonds trails in the upper atmosphere so your rocketengine must be developped by the competition already.

[Freeflyer91]

@jeremiah1st You know shock diamonds are different than contrails right?

[jeremiah1st]

@Freeflyer91 Yes I do Freeflyer but they also leave a contrail. Why developping a machine for physical transportation? You can travel from the platform called pineal gland trough time and space with much less afford and no costs at all.To me all combustion engines need way to much fuel to operate.I prefer silent flight.We cannot reach with matter what we can reach with the mind.We where always learned to ignore our true feelings because of fear it could enlighten us.I love machinery anyway.

[crapbag1997]

well thats intresting lol

[donperry1]

Love the sound at the ending

[aikidy]

awesoome !!

[tytyboo291]

I was not being completely serious, merely trying to get basic feedback that any person with a project like mine would ask. Also, you did not list the ratios or anything else, I would not either..., But basically I was only trying to figure out how many of them (If I even needed more than one,) it would take to reach the altitude I am looking for. Thank you for taking the post completely serious. But no. I actually know what I am doing, and to the extent I am doing it.

[bbrockert]

@tytyboo291 I posted the video but not the response you're responding to, it sounded like you were taking his reply as authoritative. In short, no, blueprints aren't available. The thrust is 750lbf as the text says. Later versions run around twice as much.

[tytyboo291]

Is there any way I can get the blueprints for this? I am working on a project and I am using LOX/ Isopropyl Alcohol as the propellant. It would help A LOT if I could scratch out having to design 4 of these bad boys without any plans lol And NO I am NOT trying to take over the world lol. It is for a meteorological project. How much thrust does this design give out, and about how much weight do you think this could lift? I am basing my design off of the Soyuz-U design.

[toranamunter]

@tytyboo291 hate to say it mate but if you have to ask questions like this, you sure as heck aren't ready to play with LOX :-)

[smokescreenninjato]

@tytyboo291 if its for a meteorological project i hate to say it but just use a baloon

[thewebmaster93]

How do you obtain LOX for use in a rocket? Do you produce it yourself or buy it in large quantities and store it?

[bbrockert]

@thewebmaster93 It's a commercially available industrial product, also used for metal cutting, in hospitals for medical oxygen, and at airports to recharge emergency breathing systems.

Praxair and Airgas are major US companies that sell it, it's available in bulk (like a tanker truck) or in 180 or 230 liter dewars that are delivered and rented out by the companies. A dewar is vacuum insulated and will hold the -300F liquid for quite a few days.

[adadadad95]

isnt isopropyl alcohol rubbing alcohol? becuase i went crazy with the dollar on fire trick and kinda... never mind......... OK i used a whole bottle. ok you got it out of me.

[bbrockert]

@adadadad95 Yep. Here we're using 99.9% anhydrous isopropanol, rather than the 70% you get in bottles, but it's the same chemical.

[aForkandaSpoon]

@bbrockert I don't know how but we have 99.9% isopropanol in out cabinet and 79%

[spudhead96]

how many marshmallows can you cook in a second?

[jjpjful]

looks fake XD even though i havent tried it i think it is real :D

[emerychandler]

cool could i get the blueprints to that?

[macron12388]

What do you think would be a good estimate for performance specs on a 1:3 scale?

[panzuman]

O M G those shock diamonds were phenomanal

[murdoch2486]

very impressive shock daimonds mate

[leosoheil]

isopropyl alcohol expensive

[jmontello1]

what are the advantages of using isopropyl alcohol over methanol or ethanol?

[bbrockert]

Ethanol is either denatured, which can be using questionable chemicals, or it's taxed more because it's consumable. Methanol is a bit more corrosive, but would probably work, it's about 3% lower performance at the mixture ratio we use.

[reaper151515]

@lionsforlyons  Np

[reaper151515]

@lionsforlyons yes

[Xzandon]

no bad for home rocket lab)

[lemoneasy]

really cool, especially the diamonds

[L3G3nD0001]

The white diamonds, as it was called scientifically.

[reitaman94]

figata.....

[bbrockert]

The audio is wildly out of sync, I know.

[TonyFirelli]

@bbrockert How exactly does this engine work it mixes alcohol and liquid oxygen and what is the advantage also it burns them when mixed? I'm trying to learn about rocket engines so if you could help me out.

[roboticmehdi]

@bbrockert how did you get this video, do you work there or something ?
