Long Range Mining/Exploration Rocket

Description
Long Range Mining/Exploration Rocket

Gets your drill and scanner everywhere on the spacemap
and back home again.

Pressure fed gas engine with ~33kN of thrust
and lots of fuel for those long trips.

Thrust can be increased to 40 kN potentially.

You will find the max. liquid temp for volatiles and nitrous oxide in the Stationpedia.
I picked a temperature for both gases slightly above those to prevent condensation
no matter the pressure.

Temperatures used for this setup:
N₂O: 435K (161,85°C)
VOL: 200K (-73,15°C)
While the optimal mixture is 1:1 the temperature difference of the two gases
calls for a difference in feed pressure to get to that ratio in regards of moles.
See ideal gas law. In essence the higher the temperature the fewer molecules
will occupy the same volume at equal pressure.

If you pick other temperatures you can tweak
"MinN2OPressureFeed"
"MinVOLPressureFeed"
values within the script accordingly
(I just eyeballed the numbers with some back and forth until I got decent thrust)
as the script does not calculate for that as of now.

When it comes to filling up the rocket tanks, I have both fuel and oxidizer at 48MPa.

NOTE: Higher fuel temperatures and/or bad feed ratios result in lower thrust.
The rocket update is fairly new at the point of creation of this video guide.
Expect them to change and evolve as the Stationeers development continues.

Inline tanks now have an insulated variant. Make sure to use those to minimize maintenance.

is there any changes on the O2 modification, as i remember that the ratio was 1:2 O2/Fuel.

You can find it among the screenshots here

Where is the video for the rocket assembly guide and part counts

I hope someday you made liquid rockets too :D

Yea plenty room for improvement left I can imagine. Rather meant as a "getting started guide" to long range rocketry. But good to know for when I have to update this once we get new rocket parts.

Empty space at 3 lvl is special? If you place angle on 1lvl, you can change 1x1 fuel tank on 2 to 1x2 tank on 2+3lvl

But in any case great work

Thank you... Made it in Blender mostly. Also used OBS and GIMP

Very cool video, how you made it?

Thanks... isn't it amazing what they did to the rockets? haven't experimented with O2 rockets on mars yet but same principles should apply. Temperature as low as possible within its gaseous phase. The max. liquid temp for oxygen is 162 K (-111°C). Setting it to 165 K will prevent all condensation despite high pressures. O2/Fuel ratio as you probably know is 1:3 and I'd start with an O2 feed pressure of around 15000 KPa and test my way down to maybe 10000 KPa. This fuel gives you lower thrust and I'd try three rocket segments first to test fire and see if it is in the 1.5 ballpark with its thrust to weight ratio while tuning the feed pressure.

This is awesome! I'm on Mars so N2O is virtually nonexistent. Any hints on using O2 instead? Yeah I know I can use a Nitrolyzer but looking for a lazy option
