The everlasting Thruster calculation is asked again :)

[Sgt.Morrigahngaming]

So .. after going over alot of the calculation pages, wich seem to maybe be a bit outdated, I can not seem to figure out this:
How does the weight modifier work on thrusters?? The x2, x3 and so on increase on inventory, cargo and such?
I'm playing atm on 5x for both character inventory and blocks inventory. This in my head mean that I will be able to move more items/ores as the inventory is increased. BUT.... When I then is gonna do thurster calculation ( I want to build a decent small ship to leave earth, go into space and mine PT, U, but keep it to a minimum build for fun and micro managing ), I sort of bums out on what is the minimum thrusters needed for different operations. To leave Earth, I know I will rely on O2 gen ( or maybe also a Hydro gen ), 2 Hydro tanks, 2 large storage, a Survival kit and as little thursters as possible, yet enough to safe land on the way home with full storage ( counting to use up all the ice to fill the tanks before descending.
The number of hydro thursters ( small or big ) .. will this change with different size modifiers on inventory? if so, to what degree?
Thank you all engineers beforehand for helping me out on this one :)

Let's go.

Inventory size has no effect on thrusters. Inventory size only changes the size of inventories.

Example:
Small Ship, 1x Small Hydrogen Thruster can safely carry about 8000 kg (on Earth vs. gravity and pressure). This stays true both on Realistic Inventory Size and 10x Inventory Size.

The difference comes from the fact that you can store more stuff in the same container when you set inventory size higher.

Example:
Player's inventory on Realistic Inventory Size is 400 litres. On 3x Inventory Size, it's 1200 litres. If you built a simple "ship", a platform of seats for players and H2 tank with one Hydrogen Thruster going up. All players will have full inventory, and we will assume 1 litre = 1 kg.

With Realistic Inventory Size, you could load 20 players in it.
20 players * 400 kg inventory = 8000 kg total.
On 3x Inventory Size, you could only load 6,6 players in it.
6,6 players * 1200 kg inventory = 7920 kg total.

When doing the calculation, you need to know which items will be stored on the ship you're making. Different items have different mass, or KG to LITRES ratio.

Example:
Platinum Ore has a ratio of 2,7025.
On Realistic Inventory Size, player can carry 400 litres. If you carry 400 L of Platinum Ore, it will weigh around 1080 kg.
Platinum Ingot has a ratio of 21,275.
On Realistic Inventory Size, player can carry 400 litres. If you carry 400 L of Platinum Ingots, it will weigh around 8510 kg.


You can mouseover ANY item in ANY inventory and you will see their volume in Litres and mass in kg.

---

I chose Platinum Ingots on purpose, they have the highest mass. If you built every ship as if you wanted to transport Platinum Ingots on that ship, your ships will always have enough thrust to carry anything.
But that's not really a good idea, because you would need a LOT of thrusters.

Again, an example:
A small ship with small hydrogen thrusters, it will have ONE Large Cargo Cntainer. The container can carry 46 875 litres on Realistic settings. If I were to fill it with Platinum Ingots, it would have the weight of 997 266 kg. Our thrusters would need to carry that + the weight of the ship's blocks, let's round that up to 1 000 000 kg.
1 000 000 kg / 8000 kg = 125, we would need at least 125 small hydrogen thrusters to lift it up against Earth's gravity/pressure.
If I change the Inventory Size setting to 3x, the same container can now carry 140 625 litres, so suddenly it can house 2 991 797 kg of Platinum Ingots and you would need at least 375 small hydrogen thrusters.
And that's still only thrusters for going upwards.

Finally, a guide I have favorited that has all the info I need :)

A bit of correction there: The inventory modifier also reduces the cargo mass by that same number, meaning that a cargo container full of stone will take the same number of thrusters to move regardless of 1x, 10x, or even 100x. This helps to keep builds from breaking due to inventory multiplier changes. Sadly, the readout does NOT reflect the mass reduction, so a little math would be needed, as well as a 'dry weight' reading.

The effect can be better observed by filling a craft's cargo container with steel plates, then getting some flight data for how it handles. Then take those steel plates and use them to build a bunch of armor. Now get in and see just how well that craft doesn't move, if at all.

Omg. Thank you so much.. That was actually exactly what I couldn't figure out. The changes between realistic 3x and so on. And now, looking at the fact that I have tried filling all my containers with ICE, does not seem to be a good idea, as PT and U is so much heavier.
Thanks alot Psojed for this info. I need to do some severe re calculations lol. BTW:
That page you linked, is already been fav'ed :D That one, together with one from fandom regarding thruster mechanics... But none of them did this with modifiers, so that's where I got lost. I will now go back and redesign... and actually only go with 1 Large Storage Container, as it WILL become waaay to heavy lol :D
Again mate, Thank you!

[Sgt.Morrigahngaming]

@buzzard Wait what?? So, as long as I build and I have lift, it doesn't matter if I change the modifier?
Again, As I wrote, I've been doing my testing with ICE .. and ofc seeing as there is huge weight difference between the different ores, I have failed, and will fail unless I now take this into account, but as you are saying, I don't have to take into account the modifier? Only the real weight, (dry weight)?

[Buzzard]

Dry weight, plus the (modified) mass of cargo and fuel. That handy readout on the HUD will tell you exactly what your hauling, but NOT what the modified mass comes out to.

Basically, if you build a craft in Realistic then take the same craft into a 3x or 10x world, you'll still be able to fly pretty much the same with a full load on.

[Sgt.Morrigahngaming]

Thanks all :) .. Already trying to make something for the first haul :D Won't be pretty, but can haul!!
I can't imagine ... 1600 hours in, and I still haven't made a sheet for all this lol
