Helios MID-6 Merge Inertial Dampener [superseded]

Description
Superseded by the MID-6-3, which is far smaller and compatible with my Clang Drive Manager Script.
This thing still works though and probably will for all eternity, just not with the script.


[Vanilla|"Survival Ready"|Subgrids]

The MID-6 Merge Inertial Dampener is related to all the other clang drives, but not actually a drive itself, since it is incapable of generating any forward thrust. Instead it generates thrust in the direction you're turning. You're turning left, it accelerates you to the left, etc. This allows for turning without losing speed and without drifting. Since merge blocks generate a fixed acceleration the effect will have the same strength for every ship, no matter the mass.

For how complex the principle behind it is, the actual build turned out to be super simple. It is composed of two merge blocks facing each other, one mounted on your main grid, pointing forwards, one on a rotor with a small offset. Merge blocks do not attract each other like connectors, but they do accelerate sideways in order to lign up. When both grids are rotated, the game engine seems to think the merge blocks are moving apart laterally and will accelerate the respective grids in order to align them again. The acceleration is apparently related to the cross product of the angular momentum and the vector connecting the positions of the two merge blocks. The acceleration on the subgrid merge block is negligible, since it is connected via the rotors and can therefore not move. The acceleration is also not carried over to other grids. In order to avoid any acceleration on roll (q & e), the connecting vector between the merge blocks has to be pointing forwards or backwards. Backwards however yields an acceleration to the left when turning right and vice versa, so only a forwards pointing main merge block will yield the desired result, which is an acceleration in the direction of rotation.


For placement you have to remove 7x3x7 blocks of space. The drive is only 5x7x3 blocks large and you can fill in the gaps on the sides later. You just can't place it otherwise, because the subgrids get in the way. Building it in survival is kinda tricky, you have to build the subgrids separately and attach them to the rotors and add the casing afterwards.
I have added a few conveyor lines for convenience, they are not needed for anything and you can use them freely.
You can also remove them, just like most of the casing, but be careful with the exposed subgrids.

This drive includes 2 rows of 3 merge blocks each. You can split it in half and only use 3 merge blocks, if you don't have enough space or want a weaker effect. You can also stack multiple on the same ship, but since the effect scales with mass, a single one will still be strong enough for even the largest of ships. Instead consider to add a few more gyros, since you get more out of this the faster you turn.


Some stats:
-Blocks: 103
-PCU: 2197
-Mass: 38 t
-Acceleration: ~100 m/s per 90° turn (hard to measure, probably more)


How to use:
-Place it anywhere on your ship (conveyor sorters indicate forward direction, position does not matter)
-To toggle it on and off simply toggle the merge block group called Merge Blocks_MID


Tips:
-You can remove most of the casing and replace it, just make sure not to use full blocks because of the subgrids
-It is possible to use it as propulsion by turning, toggling it off, turning back, toggling it back on, etc.
-When mounting several drives on the same ship, all merge blocks are grouped in one group and toggling the group toggles all drives (not recommended to put more than one on your ship, no matter the size)
-Want less power? turn the merge blocks off and remove a few from the group

Works rather well with the merge pump drive i had setup 2x pump drives to have a continuos drive and the Merge Inertial Dampener and im able to pull very sharp turns and get upto 364m/s in 4 seconds on a pvp server i should beable to ajust the design of the ship to have an insanely good pvp ship :D

Oh, you used my Artemis as demonstration platform. It also fits nicely into the design of my Corvette, good job! (I mean the drive and its integration into the Artemis):cozyspaceengineersc:

I have a prototype version of this with just 4 merge blocks in a 2x3 space instead of 3x5. A small ship variant is probably not gonna happen, because the small ship merge blocks are really big and weak. You would need a whole bunch of them and the thing would take up as much space as like 5 hydrogen tanks or so. If you want to experiment with it yourself, this [imgur.com] is probably the best way to do it.

I love this drive. Could you make a small ship variant of this? And if possible try to reduce the size. I would love to throw it into my fighter designs.

I don't actually plan my builds, maybe a few short sketches to get the shape right, but then I just fool around ingame until the shape looks good. But I guess atleast 50% of my prototypes never get released, because they're just not looking good enough and I don't want to waste all that time finishing them.

For some I actually exported the model (ctrl.+alt+e i think) and imported them into autodesk inventor, but that really sucked and took forever. You can also import them in the preinstalled windows 3d viewer, that was alot easier. The background and the measurements I added afterwards in gimp. That shouldn't be so hard since you can export the images from windows 3d viewer as png with transparancy. If you directly take screenshots from ingame, you have to cut the ship out yourselft and you can only lower your fov to 40. You can lower it even further with nvidia ansel, then it should look much more like a proper blueprint. Ansel also has a greenscreen function, really useful for taking screenshots.

I love all of your ships and really enjoy seeing the blueprints that show all the dimensions. I was wondering what program or how you make these blueprints. As a side question when your doing some of your bigger builds do you use like graph paper or any out side software to plan out your ships. If you do see this the dampener is great and I love your builds in general.

you can check if the merge blocks are linked, i.e. they're yellow. normally they should just link naturally when you spawn it in. If your ship turns super slowly the drive doesn't work at all, but that would have to be a really slow turn. Also i think the merge blocks can't link up if your ship is moving faster than 280 m/s, but I guess thats not the problem. Propulsion shouldn't play a role and I don't think think the other drive can cause any problems here. If the merge blocks really don't link up, you can try reducing the rotor offset, that should help.

This does not work on my ship.. placed with sorters pointing to the front, merge blocks are turned on and it was spawned with creative mode.

Maybe my merge blocks just dont like each other enough?

Does it require a certain turning radius or thrusters on fill throttle?

I'm using the "Mass shifting Drive" as main propulsion, but still have about 8 large ion thrusters as forward thrust. It turns very slowly so this could be a problem with the speed?
