What matters when you're building a rocket engine: if flames come out where they're supposed to, its working if flames come out where they're not supposed to, revert to V.A.B.

Dear SpikeViper I've been playin this game for yeeaars, and I want you to try something. Put a small-medium sized black hole. Open the console and type: !set tmp bhol 999999999 (9x9's, and remember to have Newtonian Gravity ON) Now enjoy a hyper realitic black hole ma man

Ignition doesn't take place in the bell, it takes place in the combustion chamber above it. God I can't wait to be done with work so I can try this myself...

Challenge: no clone directly in the thing, only certain amounts can go in at a time

Btw acid is also an oxidizer that actually lights fuels on fire by itself. Also if you want to use oxygen, use hydrogen as a fuel. Edit: He actually starts using hydrogen in the end, good job me.

I like how from the “The Powder Toy” genre automatic generated channel. It’s only Spike Viper xd

My ONLY problem with this... is that it doesn’t have a starter (you could use pcln, pscn and nscn)to reduce the number of times you need to redesign things because the first design could have worked with a start and stop button.

1:08 America: SPIKE GIVE US 1,000,000,000,000 OF THESE THINGS

The best thing to do a rocket in TPT is to use MORT. It burns well and it seems to never run out.

If things could bend, you could create a reed valve, a reed valve lets fluid flow through one as a vacuum is on the other side, then when it ignites, the heat creates a vacuum on the side where the fluid comes from, so it closes the valve until the ignition is complete. It’s what they use in 2-stroke engines so you don’t get exhaust gasses in the intake

They need to mix, THEN compress, THEN combust.

Actually that's a very expensive torch, there's no thrust coming out of that hahahaha

imagine how expensive this would be irl with how many times he restarted

Your engine appears to be experiencing backflow in the engine bell. Ya' might wanna address that. Also, I don't quite understand the purpose of the space between the ignition point and the engine bell, and I'm starting to suspect that you don't know the purpose of an engine bell.

you got me to get the game myself! it's great.

omg watching this is driving me insane. COMPRESSION!!!!!

It’s good to see the channel growing again (good work spike! :D)

I'm no rocket scientist, but I think after the gases mix they need to be shoved down a narrow tube where they are ignited and funnel the flame outside. Letting the gases expand before ignition is probably detrimental to the power you are getting here

you should have made the volumes smaller so the pressure would increase

You need to make a full version of “our friend, insulation”

The LOX tank should be pressurized to maintain the LOX's liquid state

Never thought I would see TPT in youtube

One time I made a high-pressure hydrolox engine that needed to be pre-lit.

yeah it generates flames but the nozzle would not work because of flow separation

If you launch incorrectly, then revert to launch. (56 sec’s ago)

TIL rocket fuel is liquid oxygen mixed with... oil.

Make a plasma rocket engine

Oh so you're whats started the TPT craze I've seen in virtual rocket scientists.

OMG i used to watch ur vids like 4-5 years ago, now I’m scrolling through my homepage and I see you

In a classic rocket engine part of the rocket fuel is used to power a fan that pulls more fuel into the ignition chamber.

Hey spike, when you have water vapor as a by product (combusting hydrogen and oxygen), you can add liquid rubidium to the mix to auto ignite the rocket.

You know resist? It liquefies in neutrons and solidifies in photons but it disappears in electricity

I like how it says more people commented than liked

Diesel makes the engine very angry very quickly.

its what we all wanted, a soap rocket

Between the chamber and fuel tank pipes is a sheet of steel that has hundreds of pairs of little holes that shoot the propellant and oxygen in an angle. So they mix and dont just fly out or create an imbalance in pressure inside the bell wich can damage it. Also, the bells both ends should have a width ratio of at least 1/70 depending on the type. Also, the pressure inside the combustion chamber can reach 300 bars and the exhaust speed can be up to mach 11 You should add kerosene and alcohol. They work really well as rocket Fuel.

Spike Viper: *I am an engineer.*

Woooo go viper

YES FINALLY SOME GOOD TPT CONTENT

someone has to remix that insulation song

17:05. Ahh yes. Airflow in space.

This is most underated game ever.

Your combustion chamber never pressurized... probably need _tons_ more fuel and a much greater reduction before the nozzle

Fuel for a rocket is liquid hydrogen, the oxygen is also liquid

If you made the are of which the oxidized and fuel funnel out smaller it would increase pressure outwards thus preventing backflow

How do you make the lines and zoom in to the precision screen?

Rockets have catalyst packs that sprinkles the fuel and oxidizer and reduces the risk of igniting the tank

Heat. Yes.

Crmc gets stronger under pressure so when you capped the rocket it just reinforced itself I think

Try to make a thermite cannon. It would fire by c4 that is constantly exploding and being cloned repeatedly, any that would force pressure out the barrel firing cloned thermite at whatever is in front of the barrel. Maybe you could test it on a planet or a city.

*r o c k e t*

I would watch if KZfaq wasn’t down.

This is the stream

combine your gasses, then add a fuse at the bottom to auto spark

the music is much quieter on the official video than the stream

I will not watch this because i watch the full live of this.

Wow- his rocket engine is way more different than mine

Scott manley be proud

Nice video.

Soap rocket!

Very cool!!!, but do you know how a rocket engine works : )

Neat

I respect that. 😔👊

14:19 Me at 3 AM in my bed

Look up rocket fuel injectors, it could be pretty neat in this.

Rocket engine maybe try plasma engine.

Youre not supposed to vent the feed pressure, in fact youre supposed to increase it as high as you can, for example with a staged combustion cycle, or turbo pumps

do something with the in game stickmen and fighters

I ran a PPG reactor while watching this

Fun fact according to fire cooler colors are hotter than warmer colors

Hey, so the glowing effect for the particles is not there anymore. Can you help?

Can you make a THDR reactor please. It's EXTREMELY energetic

Actually They have a cooling mechanism On the engine and it cools the metal and now it's safe to launch

It was combustion thats why it went through the thingy

i may sound stupid here, but how do i use the line tool in the powder toy?

Should he attempt an ion engine?

Pls make a lightsaber in The powder toy with pressured noble gas

The Bernoulli cone should be tighter

Meepmeep

How do I use line tool?

Spike use some electronics like heat switch it will block heat completely if not powered

Dont worry spiky dad!

I made the likes 607 just to annoy you guys 😈

but oxygen isnt flamable but guess it is in this game

Make the rocket engine controllable like an on and off switch

13:47 I know a lot about rockets... I don't think that's you do that..

One tip: use LOx, then you can use liquid wall to stop backflow

so, why the heck did I sub to this guy lol

5:58 "they said it could not be done" "they said i could not make it more smaller and more accurate" "they said it was designed for tanks" "they where wrong" *gets upvotes*

18:00: its a sprocket

Diesel is basically jet fuel.

Thermite rocket!

And now can it survive a proton bomb

Do an aero needle version

Okay, i gotta ask, why is your oxygen flammable? Fire shouldn't backflow up the o2 supply without some source of fuel to follow

Water is actual rocket fuel hydrogen and oxygen, that means you drink rocket fuel

the oil side looks like shrek

You say polonium I say plutonium

its supposed to combust in the combustion chamber

I got so mad when he said hydrogen rockets wouldn't be as efficient.
