You may have noticed that things are quieter around here lately. We have shifted our focus over to SimplePlanes so we can finish the 1.8 update. We hope to finish it next month and then we'll return our focus to SR2 development.

Before jumping over to SimplePlanes, Kevin and I made a lot of progress on the new procedural rocket engines. I'm really excited about them and I can't wait to start working on them again. We're trying to make them as flexible as possible to accommodate as much player feedback as we can. Here are some of the options we currently have:

  • Engine Type: Liquid, Solid, Nuclear (thermal), Ion
  • Power Cycles (Liquid only): Gas Generator, Staged, Pressure-Fed, Electric
  • Fuel Types: Kerolox, Hydrolox, Methalox, Solid, Liquid Hydrogen (nuclear thermal engine), Xenon (ion engine)

There are also several nozzle options available. Most of them are fixed geometry, but there is a procedural cone style and a procedural bell style you can adjust to get the exact nozzle area ratio you want. This will allow you to optimize your engine for sea level, vacuum, or anywhere in between. We will also include an altitude-compensating toroidal aerospike nozzle.

Also, Philip did a lot of work to improve support for building airplanes in SR2, including a new option to specify if you are building a rocket or an airplane. Parts will adjust to a more convenient orientation when added and you can also adjust the direction of travel using this new handy gizmo:

In the same aim of improving support for building airplanes, William has been working on adding resizable landing gear. They are still in the early stages of development, but they already show a lot of potential.

We're hoping to get most of this out next month as well, but that will be a tall order! We will do our best!

    That pilot (?) and resizable Landing gears are a big help too back in SP.

    @talhahtaco My guess is most likely no. The game is still in early access and each update changes a lot of stuff.

    @zapper071 yeah that will be more than fine most likely

    I know the answer is probably no but any estimation on when at least the engines will release (at least on beta)? I've been checking like every day since this was posted lol.

    Will this be able to run on an iPad Pro 10.5”? It's a pretty powerful iPad (runs models on SimplePlanes that should crash it on max settings) so I think it'll be fine.

    @czenon1 I don't know about your first question but the answer to the second question is probably yes with mid-spec phones maybe able to play the game at 30-40 fps at very low graphics

    @AndrewGarrison, Hello, i have a big questions.... Does SR2 will support Linux, because i swich to this os to get more from my pc, and, if SR2 comes on Android, does the mobile version will need big specs to run or not ?
    Thanks for everything.

    @mjdfx150529 I mean, there`s no powerfull Monopropellant engines like those on Proton, only RCS.

    @AndrewGarrison What about hydrazine fuel?

    @AnotherFireFox Yeah... realised that afterwards. I thought it was just a made up fun name lol

    1. Hydrolox is a general term for Hydrogen + Liquid Oxygen
    2. So yes
    3. I hope so

    Looks pretty good but I have a couple of questions:
    1. Is hydrolox hydrogen or hydrazine? (or something else)
    2. Will liquid hydrogen also be a fuel for regular engines? (Look at the space shuttle and SLS)
    3. Will there be cryogenic effects (ie, leaking fuel at 1%/X-hours)

    Is there a SR2 wiki yet? I could make one here if you want.

    Can't wait for procedural engines, it's one of the things I've wanted in a space sim for a really long time. Finally will be able to optimize engines for specific stages and vac. vs asl.

    @talhahtaco The mobile release is this year. And about ignitors, they are too complicated and without the sophisticated flight planning tools available to the real world engineers, too limiting on the gaming experience.

    also can you ad an ignitor system

    @aircoolbro21 no matter the grid size, it is 1:1m

    @mjdfx150529 ok ok, new question thats pretty much the same, when you go into the shaping tool and u change the grid size to 1 how big would that be in irl units of measure?
