I feel like it's nice to have that vertical dimension as condensed as possible in that application. Probably? The only functional parts around there are the turbopumps (very small actually for the volume of LH2 that may need to flow through there), and the propellant lines. Those bends are important so that thermal expansion/contraction doesn’t rupture the pipe. I’d also like to point out the cycle of the engine- it looks like both turbopumps feed LH2 into the reactor, but I don’t see a second pipe to input into the nozzle for the LOX input. (There is a set that leads from the top of the reactor into the boattail, but I believe it’s for a coolant being sent to the radiators). Also- that joint where the 2 pumps join outputs looks a little questionable. Edited October 1, 2021 by Clamp-o-Tron Quote Link to comment Share on other sites More sharing options...

Honestly I think it was finished some weeks before and it was just shown, because it was just something small to show. Quote Link to comment Share on other sites More sharing options...

Higg poly model from low poly concept, materials, textures, animations, probably also exhaust effects, behavior, parameters... I assume now it's ready to be put into the game as finished product. So yeah, that took 3 months, because there were probably few other things to do as well in that time. Jeez. Quote Link to comment Share on other sites More sharing options...

The model was almost complete. The animations are not very complicated. The exhaust and parameters are not visible in the video, they are made by other specialists, it is not known whether they are ready. We did not see the engine in the game. I would like to remind you that the game was announced for 2020 Quote Link to comment Share on other sites More sharing options...
Wubslin Posted October 1, 2021 Share Posted October 1, 2021 I have a minor question. When we actually start building with these engines, is there going to be some kind of low profile mode like in KSP 1 where we can mount these engines without that large engine plate-looking structure?

Deddly Posted October 1, 2021 Share Posted October 1, 2021 @Alexoff, I would love to know how game development works in your mind. Do you imagine an entire team all working continuously on a single part non-stop until it is ready, and then move on to the next one? Can you think of any other possible reason why we are only now getting to see the final model? Quote Link to comment Share on other sites More sharing options...

You can see the rods inside the vacuum nozzle when it is retracted. Minor bug. They will actually retract like the strings on blinds -- you won't see rods impinging on the nozzle interior like this.

Synonym Toast Crunch Posted October 2, 2021 Share Posted October 2, 2021 9 hours ago, Inglonias said: Wouldn't it be advantageous to let us run the afterburner with the nozzle in vacuum mode as well to increase efficiency when firing high-thrust in a vacuum (IE something like Tylo)? Something like an in-beween? A good idea would be for the nozzle extension and afterburner mode to not be linked. That is, they don't have to happen together. The nozzle could automatically extend or retract when you reach a certain atmospheric pressure, while the afterburner would only switch when you manually switch it, or maybe automatically if you're above a certain TWR, but they don't have to happen at the same time.

That is, they don't have to happen together. Fully agree. I'd like to be able to use the lH2 only version in thicker atmospheres, when high TWR isn't needed, such as on something like Titan. I'd also like to be able to maximize vacuum dV even when using the high TWR afterburner mode, such as when landing on Tylo.

Well, I think automatic switching would be convenient, like the autoswitching on the rapier... but I can also imagine wanting manual control over it, such as making somewhat shorter vacuum landers: retract the nozzle before touching down. I can see 2 ways this works: 1) a toggle for the nozzle, and a toggle for the afterburner. The first dynamically changes the atmosphere Isp curve for the engine, the 2nd dynamically changes the overall Isp, thrust, and resource consumption (adding O2). I'm not surehow much of a change to the game engine this would require 2) a multimode engine with 4 modes. If I'm not mistaken, already we can have 3+ engine modes in the game code, even if we only have engines with 2 modes (rapier, panther). This would be a little awkward to switch between modes, as you'd have 4 modes to cycle through to get the one that you want. I imagine that mostly during a burn, you'd be going from high TWR and atmo pressure, to low TWR and low atmo pressure, so I'd have the order go: i) Afterburner, nozzle retracted; ii) Afterburner, nozzle extended; iii) No Afterburner, nozzle extended; iv) No Afterburner, nozzle retracted; This would allow easy cycling during a burn from the surface of a planet with an atmosphere. In this case, generally you'd want: 1st, high TWR and the nozzle adapted to a high ambient pressure. 2nd High TWR, but an extended nozzle as the rocket climbs. 3rd low TWR and high Isp as you circularize your orbit. The no afterburner, nozzle retracted case isn't needed. If you want to land on something like Mun, you'd probably not want the afterburner, so you'd go from no burner, extended to no burner, retracted (for touchdown) - this order works again. But it would be inconvenient when you want to land with the burner on, but the nozzle retracted, supposing you come in with burner on and nozzle extended (such as on Tylo), you need to press the cycle button 3 times rapidly to get to the burner+retracted mode for landing. Similarly, taking off from Mun with the mode initially being: no-burner, retracted - if you want to switch to no burner, extended, you'd cut the engine, and have to cycle 3 times to get to the mode you want... So if we can't just have independent toggles for the burner and the nozzle, 4 modes to cycle through would be a bit annoying. Quote Link to comment Share on other sites More sharing options...
