Stationeers Let's play Mars 45 Blue flame rocket

Today, I read the instructions. Then, I do math. And then, I redo the math correctly. And finish with a NOS rocket.

[@brandonlaird6876]

Wait, do you mean to tell me that math actually helped with rocket science? This changes everything! Quick, where's my abacus‽

[@TheChaemera]

We need a timer for "how long to realize the difference between liquid and gas pipes."

[@cowsareevil7514]

That was not my best assembly work.

Hey Mick, thanks for all the great videos so far. I would like to tell you that I am now the proud new owner of this game. My family has gotten sick of me talking about it and bought it for me for father's day. This is entirely your fault. For that, thank you! Lol

[@lonniefennel4024]

Addendum, of course the tutorials are broken at the time of me getting the game... 😅😅😅

[@witgangyounotube287]

thanks for testing liquid engines! I'm playing on Vulcan and want to make my first rocket run on liquids , not that hard to cool down with cascade phase change setup, the trick is to not cool the entire thing from cold end but just pump it trough each stage and gradually cool it until it reaches the cold end temperature. got about 6k litres of liquid volatiles and 50k mols of gas oxygen that I haven't started to cool yet.

[@NavyOldsaltGamer]

WOW! Awesome episode! First time I have seen the engine fired. Hope to See it launch!!!

[@muraj7418]

Nice! As to whether the NOS is worth it, would some gas harvesting + the nitrolyzer tip the scales much? My bases are usually fairly low powered so I haven't had much experience with the nitrolyzer.

[@cowsareevil7514]

1 nitrolyser = 20kW. My entire base = 15kW. So probably not worth it. Now that I have found NOS ice in space, that is the best way to get it.

[@shadowdrake082]

Those are the values I got as well. 72.7% for vol-oxygen fuel and 60.6% for Vol- Nitrous fuel. Being able to get 31kN of thrust on a fairly simple rocket (compared to pressure fed at least) is really hard to beat. I'm interested in seeing your approach to pressure fed liquid rockets and see if you can get a fairly stable thrust. I'm on my 4th revision pass on the controls for mine... Had a few accidents though. Apparently liquid fuels just combust when exposed to air... doesnt make much sense to me but oh well.

[@cowsareevil7514]

I haven't tried yet. I have an idea for the NOS/Vol but no idea about the Ox/Vol.

[@n0mial]

Maybe using a single pressurizer line connected to both fuel lines through a check valve with nitrogen gas at 5 something MPa. You will lose a bit of efficiency mixing the N2 but it should be much more stable when used to pressurize both tanks.

[@shadowdrake082]

@@n0mial Last I tried to use pressurant nitrogen, it actually condensed fully and left oxygen to be the pressurant gas.

[@alekseyg4806]

i think you need one button to connect all connection for charging rockets.and you really need safety command post :D

[@cowsareevil7514]

Yep. 1 switch to set everything, connect, refuel, unload.

[@lange1815]

And BTW the temperature matters even for liquids becouse the ratio of liquid moles per gas moles is higher at lower temperature. I guess the liquid engine only uses or prefers liquids so gas won't be used in the engine but it adds weight to your rocket you don't want to carry around all the time. For expansion I thing the game does not work correctly and increases volume of warmer liquids compared to colder once but I could be wrong. Anyways that wouldnt change much cause the difference is sooooo small.

[@lange1815]

And sorry for another comment but: you can connect liquid utility inline tanks directly to the engine input. Saves you some space and grants you volume!

[@stormfire962imastarcitizen5]

Mick - minor question since I never built a rocket in game. Is there any required order in which to position all the parts in the rocket build and is insulated items required as well or is that just a personal choice?

[@cowsareevil7514]

You can build it however you like. There is not a lot space in the rocket, so I like to put in the larger pieces starting from the bottom with the fuel tanks trying to visualise where all the pipes and cables will be going. Things like avionics and datalinks can fit into any little gap you have left.

[@stormfire962imastarcitizen5]

@@cowsareevil7514 Thankk you for the reply back and the info sir.

[@mwwoggy]

Are multi-stage rockets possible? High power to get it off the launchpad and then better efficiency for the space travel. perhaps by putting 3 tanks in it and then using a chip to switch between NOS and O2?

[@cowsareevil7514]

Multi stage is not possible. Typically IRL better efficency means less thrust. Here you get better effiency and better thrust so there is no benefit to having multiple engines.

[@walterverlaan1286]

Great job.

[@lange1815]

I did spent two hours in creative to receive the following mole per volume data for the Pumped liquid engine fuel tank ratio. These are for the coldest possible temperature before it starts to freeze and ment to be use for calculating the volume of liquid tanks you need for volatiles and n2o so that you can aim for equal mols becouse the perfect mix is 1mol to 1mol: VOLATILES 7kpa at -191°C Mol: 23,9 liquid 0,398 gas Volume: 0,955L => 25mol per liter (only the liquid part) (5kmol = 200 Liter 10kmol = 400 Liter 12500mol = 500 Liter 20kmol = 800 Liter 25kmol = 1000 Liter 31250mol = 1250 Liter 50kmol = 2000 Liter 62500mol = 2500 Liter) NITROUSOXIDE 810kpa at - 19,9°C Mol: 97,6 liquid 14,4 gas Volume: 2,54L => 38,4mol per Liter (only the liquid part) (5kmol = 130 Liter 10kmol = 260 Liter 19200mol = 500 Liter 20kmol = 520 Liter 25kmol = 651 Liter 31250mol = 813 Liter 50kmol = 1302 Liter 62500mol = 1627 Liter) Hope it helps you if you were curious about the correct ratio for your tanks without just guessing and testing how much of n2o or volatiles is left after your flights.

[@lange1815]

Oh fuck.... Didn't knew the liquidgastype site in the station Pedia is showing the values as well.... So much time wasted on this one😮

[@cowsareevil7514]

The density of the liquid seems to be constant. The NOS and Volatiles had a huge temperature difference and there was no error in the combustion.

[@MakarovFox]

liquid is the best obviously is more complicated to produce butt is more powerful
