Zorg

Thats not really abandoned, I did update it a couple of months ago as well although planning started a VERY long time ago lol. But I only tick things off once I get a functional version in game and relatively stable. There might be a couple of omissions, I'll go over it again soon. About half that list is modelled and textured now (and more than half workload wise). I will probably do this in two phases so most of what I've shown is going to go start going in game once I've finished the emissives for the engines. Most of whats in that list starting with SLV-3X and below will be phase 2 which I will start on once I get phase 1 in game. ps. By phase 1 and 2 I just mean in terms of my work. All of this likely will be part of the same BDB update.

LR-101s Includes a fictional ultra compact mount, a bare version of the historical mount, and three colours for the full version with aero covers. (The red was used on some Atlas A launches)

The other models don't have modeled turbo pumps at all. The pumps are shared and located centrally in the skirt which isnt feasible to model or practical in game. So its abstracted out. Atlas E/F was the final evolution of the Atlas missile and the USAF wanted the engines to be fully independent so they could be serviced easier. So in this case we have a fully modelled powerhead. The shape of the Atlas E/F skirt is also different to the others to accommodate this.

LR-105 update How these models work out to combine for the different variants, the MA-powerpacks, and associated rockets.

Its best to ask there since the RF configs for BDB are provided within RF stock.

Those engines use liquid fuel by default. There is a patch however in BDB extras that converts some engines to use hypergolic fuels. BDB extras is not meant to be installed as a whole. Users are meant to pick specific extras if they are interested and install only them (or none at all)! There are multiple warnings in that folder.

LR89 progress. Mostly finished texturing but will do the emissives for all the engines together. Most LR89 models had shared turbo pumps which were located in the center of skirt. That aspect is of course abstracted so these simpler models will be used to represent those variants. Left is the RS56OBA (MA-5A) model and right is intended to be used for XLR89, and LR89 NA 3,5 and 7 (ie MA-1, MA-2 and MA-5 power packs). Only difference is some nozzle detail. We also have here the fully independent LR89-NA6 (MA-3) for Atlas E and F. The powerhead just barely fits inside the special Atlas E/F skirt (which had a different shape to the others for this reason). Due to the odd shape and clearance requirements, a separate whacky ring mount is provided as a switch for generic use. Full lineup of LR89s

Cobalt made those so you would need to hear from him but I can say that its unlikely unless there's some space on the sheet as you need to map a different UV island near the end of the tank due to the baked ambient occlusion (assuming there was motivation to do this to begin with it can be hard to work up the energy to work on files long since completed haha). Its a somewhat tedious thing anyway which is why the Atlas tanks only have this on one end.

Thanks! And yeah I will put together a build guide table or something before this is done so Friznit can adapt it to the wiki when he has time. Worth noting the performance charts will also become obsolete most likely.

Box of balloon tank shaped Lego for all your Atlas building needs. Even if not mentioned all historical variants can be built accurately with correct combination of these tanks. Cylindrical extension tank raceways can be switched to be open ended for stacking since some variants need one underneath a conical tank and of course lets you use them in any combination you like as well.

Atlas updates. Aft tank today We also now have a dedicated mount for Atlas SLV-3X "Fatlas" that can mount H1D. It will match the ring and there's no clipping. This aft tank will fit inside the standard skirt. The H1D will need to mount at a 45 degree angle (the prop inlet pipes will guide you) and though its close it just about fits You may want to lock the gimbal until skirt sep

The unity tag is used only on the base tank to prevent surface attach on most of it while allowing it where the LR101 attaches. The other extension tanks all use the regular config rules.

The issue of how to handle surface attach hasnt been decided yet. On one hand the no surface attach concept was something that helped distinguish the balloon tanks and worked as a balancing factor given how much better the mass fraction is compared to other tanks. On the other hand we do know a lot of users like decals and there is a lot of scope for fun decals on the Atlas series especially the various test launches. I'm probably leaning towards allowing surface attach. Even on the current base tank model you can surface attach to the LR101 mounting points and slide things up whether its decals or other things so maybe it doesnt matter so much other than making things awkward.

Some more Atlas updates. Got Atlas II (technically Atlas IIAS with the ring for the boosters but its going to be a combined variant as it will be wasteful otherwise). Middle is SLV3 which has a longer left side avionics pod than Atlas D and LV3 (on the left). Atlas III Since its not been seen in a little while :P

I believe its just a safe value for jettison on all variants that should leave the core with more than1:1 twr after jettison. You should tune it per LV if you want to optimise.
