Rocket Control Unit and Low-Density Structures

I wanted to share my designs for RCU's and LDS. Requirements are:
- input: plates, plastic and circuits
- belts-only
- every assembler gets max productivity modules
- as many beacons as reasonable are used
- try to be close to perfect ratios and use direct insertion where possible
- tileable designs ('racks') that share beacons where possible

Rocket Control Units (RCU)

Each RCU requires 1 blue circuit and 1 speed module, which in turn requires 5 red + 5 green. Speed modules are produced twice as fast as RCU, and don't take prod modules, so the ratio is even more skewed. Rather than trying to use one sp1 assembler per 2.x RCU assemblers, I decided to speed boost the sp1 assemblers less and do 1:1 underneath the beacon row:

The ratio is still off, as the sp1 assemblers have speed 3.75 while the RCU assemblers have 5.5, but I'm not too worried about 'wasting' sp1 assemblers as they don't have modules.

Each RCU assembler consumes 2*5.5=11 blue per minute and 55 red and green to produce 2*5.5*1.4=15.4 RCU per minute. So, a full belt each of red and green (2400/min) is consumed by 43.6 assemblers (22 rows) and will produce 672 RCU per minute. Note that if this is enough, you can also combine the red and green belts into one belt, but as I needed more I have two full belts.

Low-Density Structure

LDS consume three raw resources only, so it is easiest to just have racks with two belts, and use one lane for output to be sorted at the end of the rack:

(The LDS are looped through the inserters and output at the bottom)

Each LDS runs at 5.5 speed, using 5*5.5/30=0.916 copper/plastic and 1.83 steel.
So, a blue lane of steel can feed 10.9 assemblers. This setup has 2x11 assemblers, consuming a full belt of steel and a lane each of copper and plastic to produce 335 LDS per minute.

As a "bonus", this is my blueprint for heavy-duty combining of 4x2 belts into 8 mixed belts:

Re: Rocket Control Unit and Low-Density Structures

Hello 4 year old post, I noticed your blueprint strings are incompatible with version 1.
Does anyone have these blueprints and could you please share the new blueprint string please? I very much like the look of the low density structure factory and would like to use it in my game, especially now that yellow science uses this as a component.

Decided to have a go at making the blueprint myself, it uses splitters to filtre out LDS from Steel plate.
Alas, copper doesn't get all the way to the end and because of this I have modified the inputs so there's three pathways for copper.

Code: Select all

Re: Rocket Control Unit and Low-Density Structures

I seriously doubt anybody both has these for a current game and will see this thread and remember it.

If I were you I'd just follow the images and make blueprints of my own.

Note that a 4-year-old build may not even work correctly now. I have no idea if the recipes and ratios are the same as they were back then.

The low density structure design should still work in 1.0 but isn't useful due to game changes. For a similar layout using assembling machine 3s with 4x productivity module 3 and beacons with 2x speed module 3, a column of nine machines will consume an entire express belt of copper and produce 189/minute.

Try this, which takes two express belts of copper, half an express belt of plastic and 1/5 an express belt of steel:
