no, right now peroxide decay is not modeled.
I see. Is this something that is hard-coded into the plugin, or can it be tweaked through configurations?
I had this question come up because I've written up some elementary RF engine configs which use HTP, and read up on it. http://forum.kerbalspaceprogram.com/threads/60853-0-23-5-Alchemy-Technologies-products-v02?p=1363582&viewfull=1#post1363582

I've written RealFuels configs for the "critter" engine series. It's not much, but I hope it contributes to both mods. Back when I was playing without RealFuels, I used these engines a great deal for space probe propulsion. Now I've gotten into RealFuels, and felt like this needed to be done. The engines have been balanced slightly. They have only been partially tested! I'll update this as soon as I test everything (there might be errors in the configs). The engines run on two major monopropellants - hydrazine and high-test peroxide; hydrazine is more efficient, and HTP has much higher thrust (also, it's supposed to decay inside the tanks slowly, but I guess RealFuels doesn't simulate that yet). There are also three bipropellants available: MMH, UDMH, and Aerozine. No ullage simulation is in any of the configs - the fuel flows are considered to be pressurized.
By the way, some of the engines are made redundant by the ability to choose a fuel, so I didn't do all of them. Only the pertinent ones, one of each size. The rest can be deleted.

I have a question about the mod's features: does high-test peroxide decay inside the fuel tanks the way it's supposed to? LOX and LH boil away, but is there a similar mechanism in place for HTP?
-
I should probably help reanimate this thread as well, since I've been using this mod since 0.23 was still fresh. It's a fantastic mod, elegant in its simplicity; it provides a lot of parts that should be in the game, but aren't. Those monopropellant engines are probably my favorite part, and I also tend to use the tiny structural elements a lot in building my probes and unmanned landers.
Come to think of it... I'll put together a set of RealFuels configs for the aforementioned engines. That ought to get more awareness for the Alchemy Technologies mod! Plus, since TweakScale doesn't work with RealFuels (yet?), having multiple different engines makes perfect sense.
-
7.5m parts? Well now, that changes things quite a bit. Granted, I'd still like to have more conventionally-sized ones, but this is rather exciting. In that case, how about having a cluster of nodes on the back, for the option of having other engines? Also, would it be possible to get nose and tail parts like these that are compatible with S2 parts? Anything compatible with B9 tends to get very popular.
-
I have a suggestion! Your fuselage parts look very similar to two existing mod components: the B9 Aerospace S2 system (the profile on those is octagonal; squares with flattened corners) and the Lack Luster Labs hull system (Lack has some components with very square faces; also, he's already got numerous engines compatible with that form factor, including open-cycle nuclear ones that I've had great success with making spaceplanes!) - it would be magnificent if you could make these parts compatible with either of those mods. The S2 shuttle hulls would do well, they already have good textures, DRE heatshields, numerous stuff like cargo bays, adapters, etc.
Either way, please make your mod modular (i.e. making it possible to easily attach other parts to yours, like for example putting very different engines on there) - this is the feature which makes a good mod used by some into a great mod used by everyone. For example, KW Rocketry and NovaPunch, versus Bobcat's work. Bobcat has made some truly magnificent parts, and I've used them a lot, but they generally have weird sizes; for instance, his Soyuz rocket is neither 1.25m nor 2.5m, it's in the middle there. I have to either use Procedural Parts to make adapters, or resize to 0.64 scale.
Either way... Keep up the good work, I'm big on spaceplanes and will look forward to yours!
Edit: actually, here's another idea, since I'm actually thinking about the cool potential here. If you do end up making these square-faced spaceplane parts, please make sure to post the specifications of the faces that the parts have - vertice for vertice, so that modders can make completely seamless parts to complement yours! I wish bac9 did that with the B9 Aerospace mod...
-
Naten, are you going to make any more additions to your clusterable clusterengine? Clustered surface-attach engines are perfectly compatible with the new interstage fairing part from Procedural Fairings, plus I've been on a roll lately doing RealFuels configs, I could contribute to your parts in that regard.
-
searching further, the thrust for 0.625m engine should probably be closer to 10~15kN range.
I'm inclined to disagree here. The LM descent engine was a type O (low thrust, high vac efficiency, abysmal atmo efficiency); these are type A (high thrust, superb atmo efficiency, lackluster vac efficiency). Moreover, these already have somewhat lower thrust and slightly lower efficiency than plug-nozzle aerospikes. Besides, the nozzle area is quite huge compared to conventional bell-nozzle designs; compare the 62.5cm Eddie to Frizzank's Agena engine. The Eddie already takes a significant dip in thrust output by comparison. I'd say the surprisingly optimistic numbers are pretty close to reality! I'll have to tweak heat output next, because as it stands, the engines melt at 100% after about ten seconds.
-
Momentary digression from the rotary propulsion delights - I've been thinking of how to accurately scale the masses and thrusts of the Eddie engines. There's this page: http://www.alternatewars.com/BBOW/Space_Engines/Rocket_Engine_Scaling.htm
Basically, double the size, quadruple the thrust, triple the mass. So... 0.625m Eddie at a mass of 150kg and a thrust of 30kN, at 1.25m is going to become 450kg and 120kN; at 2.5m, 1.35t and 480kN; at 3.75m, 3.0375t and 1.44mN; and at 5m, 4.05t and 1.92mN. What's particularly interesting is that at these juice outputs, the engines become conspicuously interesting as first-stage engines. They lack the thrust of bell nozzles since I guess the pressure at the plug must be kept low to keep it from disintegrating (yes, I'm aware that the initial figure of 30kn for the 62.5cm one is an intuitive figure, to put it mildly), so that keeps everything at comparative advantages. Did you know that NASA considered using aerospikes to propel the first stage of their Nova rocket, the successor to Saturn V and a potential Venus/Mars mission launcher?
-
Ah, so you will make a separate version of the Jey-Tew without the engine body? Please say it shall be so
I can just picture that engine on the back of something that looks like a Predator drone, it'd look magnificent!Something crossed my mind - figuring out how to make jet intakes for the gas turbines work is going to take some ingenuity. In essence, a propfan deals with two separate air streams: one that's eaten by the gas turbine, to combust fuel and drive the propeller gear train, and another that impinges on the propeller blades, to drive a massive airstream for propulsion. If I make the engine take only one source of air - from the jet intake - it will need a lot more air than the intake can provide, and if I artificially make it provide thrust out of nothing as a function of the air that goes into the turbine, all of a sudden we've got an engine with all of the advantages of both jets and props, and none of the disadvantages. Basically, all I want to do is just make people stick an extra air intake on their airframe... Well, I'll come up with something.
...I've just had an epiphany. The gear train! In a propfan, it's a step down gear train, not a step up! The propeller is supposed to spin slower than the turbine! That suddenly makes the crazy numbers I was seeing before make so much more sense!
-
I have tried every one of the engines with a brief test flight and can offer some initial impressions.
First of all, these things look utterly amazing. The closest propellers to these in terms of sheer attractiveness are the ones in the D12 Aerospace pack, and these blow them out of the water: you've got cooling vents opening up on the nosecones, tiny 3D features on the engines, everything is moving, and the textures are beautiful. Speaking of which, my game actually crashed on the first load, but that's because I probably have over 2gb of mods installed.
Second, the engines are wildly overpowered (perhaps my AJE mod is doing something to them; it certainly switched LiquidFuel to Kerosene). I effortlessly passed Mach 4 and got as far as the thermosphere before the engines would flame out, and on a few occasions, parts were torn off from my planes due to the excess Q on the flight body. If I'm going to balance these for AJE configs, I've got some work to do.
Thirdly, it's clear that at least two of these are scientifically accurate gas turbine propfans (the red-hot cooling vents remove all doubt). In that case, the engine needs a separate air intake somewhere, just like a jet engine! Surely a relatively small one would do, since the turbine mainly just drives the propellers. This should be an easy config file mod, I'll see how to make it realistic.
Finally - for some reason, the texture on the V12 engine body wouldn't load. It's beautiful too, I can tell; there's some kind of cyclone air intake on the side, very cool. I don't know if the issue is related to the memory load (it shouldn't be). I also have a suggestion! Release the V12 engine body separately as a structural part, like the other radial engine bodies available for KSP, and provide the straight-blade prop as its own part, exactly like the other engines in this pack. That way it's possible to arrange the vehicle how you want it; I use Procedural Parts and the engines look especially beautiful on a rounded conical part. There exists a mod which makes the engine bodies actually act as engines, too: http://forum.kerbalspaceprogram.com/threads/61717-InfiniteDice-ICE-An-alternative-Engine-Module-for-Atmospheric-Vehicles With it, it would even be possible to have multiple props powered by one engine, I think. I'm not too familiar with the mod in question. By the way, there is a module available which reverses the direction of a prop engine's thrust (D12 and Lack Luster Labs use these). I'm actually going to try and do some of these modifications to the config files, and pass them back to you.
All in all, fantastic work! These have the potential to become just as well-known as B9 Aerospace parts!
-
Here's a very, very early draft for the first engine in that picture. Not suited for use until I actually test everything out. I tried to copy the stats of the D-27 as closely as possible, pulled straight from the manufacturer's website and Russian wiki articles. For the blade pitch and gear ratio, I had to use intuition halfway. I have no idea how this is going to look in-game, and will have to wait until I have the part files before I can try something. Also, had to do one heck of a unit conversion for the specific fuel consumption at Wolfram Alpha, I hope it's not going to be a case of math failure. I'm looking at these numbers and starting to freak out a little bit, because this engine is ostensibly a nightmarish fantasy beast. I mean, 11-plus-change thousand horsepower at almost nine thousand RPM, with a blade pitch of 16 degrees... Well, maybe AJE will surprise me by having it work as advertised...

Got it. Pistons all the way for the fourth one. Shinden! All right, that's another IRL set of numbers I could gnaw on, then. I've found detailed stats on the D70, so now I'll try to make heads or tails of them in context of the AJE mod. There's not much in the way of documentation, from what I can see.
-
Hmm, I see! That will make writing the first two configs relatively straightforward, I'll try to make the second engine a downscaled version of the first. I'm going to try a few configurations with the last two, and will likely stick to either subsonic for all of them, or very mildly supersonic for the first three. They really do look like they're all driven by turbines!
-
Well, KAS would work, as he says. For example, the Universal Storage mod has an EVA-X backpack which a Kerbal can pick up manually on EVA. Something like this could be picked up on EVA too; the helmet would clip around the existing model. Kind of a kludgy solution, but it's an idea, anyway.
-
I've done some snooping around to try and determine how the engines will work. All of these beauties are clearly propfans, perhaps with the exception of the one with straight blades, but the twin-rotor design and the gas turbine exhaust vanes in front of its nose cone suggest that it too is a propfan like the others. That's what you had in mind, correct? This is pretty exciting because I don't think there are any propfans modeled in AJE to date. These are prop engines driven by turbines, as opposed to piston engines. For the big 14-bladed one, I'll try to copy the stats of the Progress D-27 (http://en.wikipedia.org/wiki/Progress_D-27) and I'll work from there for the others. AJE is actually a very strange, in-depth mod with more math than RealFuels rockets. Hmm.
Edit: I forgot to ask. That cockpit, the pointed one - I've never seen it before, I presume it's your work as well? It's magnificent. I can just imagine it working on a mini-Skylon. I look forward to trying it as well.
-
That's terrific. I can help out with doing vanilla KSP configs too. Writing config files is enjoyable for me, believe it or not! I must have about a hundred KSP-related tabs open in Notepad++ right now, heh. I used to do this for Naten, wrote curves for a couple of his engines, including a scramjet. Some people build space stations, some build colonies, some do stunts... My two great passions are unmanned probes (I've done planetary landings with RemoteTech 2 signal delay!) and spaceplanes. Well, that, and lift bodies; I get great edification from building efficient, attractive multi-stage launchers, which is why I'm all over RealSolarSystem now.
-
WOW. Your art is amazing, right up there with ZZZ and Frizzank. I build a lot of aircraft in KSP; those props and the cockpit are amazing. Would you like it if I tried making some AJE configs for these engines, the same way I did for the Eddies? I've never done AJE configs before, but this is a great chance to learn.
-
Splendid, I'll be glad to see how this develops, as I'm sure many others will be!
I also always figured it would be cool if individual Kerbals had a backstory. Just for flavor, at least at first. Like, this one is a military pilot, that one is a scientist, etc. I think there's even a mod out there that gives them space suits with custom-colored stripes - red was medical, blue was engineering, etc. Anyway, that's just a side idea. I'd be satisfied with just the customizable faces, names and genders.
-
Why as a matter of fact, there's a perfect hatch for that in the Lack Luster Labs pack. I'll rescale it to half size and see what I can do.
I'll also see if I can draw up a new texture for the capsule. Wonder what to stick in those "vents"... They look so out of place.
-
Agreed! TextureReplacer has a plethora of different suits and faces available; including both male and female models. The faces and suits can be linked to specific Kerbal names. Would it be possible to include integration for that in this mod?
-
In case someone still needs these, the original upload was mirrored on Curse by someone. http://www.curse.com/ksp-mods/kerbal/222569-the-original-kerbal-space-program-parts-pack
"Rip that sucker right off the pedestal - it's going bang, zoom, straight to the Mun!" would make a good description.
It doesn't have a hatch though, so you can't do EVA. :\ I think the old pod needs a retexture, a hatch, and an IVA. Actually, the way it is, it could be a good tech level 1 pod before you unlock the Mk1 at the next level: no hatch because EVA has not been worked out by Kerbal engineers yet. Compensate for it by making the pod lighter.
-
I've updated the config a bit more. The original post was edited. Next up I'll work on the engine masses. There's clearly some work to be done there: other aerospike configs don't weigh as much, and I already made the engines have slightly less Isp than plug aerospikes, so it all has to be balanced.
Maybe I should grab HyperEdit and experiment with these on Eve...
-
Oh, absolutely, include it! I'd be delighted. All I ask in return is that my name gets mentioned. I'll keep tweaking the configs, too; I think the thrust levels need to change a bit, for one.
Generally, the engine masses in stock KSP are nerfed to match the feel of a small-scale star system. And, of course, there's only one variety of propellant, with one fixed density. I have a gut feeling that the largest Eddie engine should weigh less than 2 tons for RealFuels/RSS. It can't be too light, but still. For example, the KW Rocketry SPS gets buffed from over 2 tons to less than one ton in the mod. I'll give it some thought and amend the file after some comparisons with other aerospikes.
As far as changes to the basic design go - besides the improved thrust vectoring to reflect the advantage over a plug aerospike (a base 15 degrees should be pretty good for the regular versions, too) I doubt there's much that needs to be done, but if you are interested in animating the nozzle changing shape as the thrust is vectored, that would look very cool indeed! I was always a fan of the fluffy-looking red-and-blue flame these engines make, too, even though it's likely not realistic IRL. You did a great job with the engine FX.
Speaking of aerospikes, there was a really good mod one or two years ago - Kerbolar. That mod had several conventional aerospikes as well as a stackable linear aerospike kit; you could assemble long linear aerospike "sticks". I felt like it would be great if they could be surface-attachable, like control surfaces get attached to wings. It's a very cool idea. The maker hasn't logged into the forums since January. I sent him a message. If he does respond, and is interested in passing the mod along, would you be interested in bundling a few of those aerospikes together with your mod? I've already got some configs written up both for stock and RealFuels.
I can just picture that engine on the back of something that looks like a Predator drone, it'd look magnificent!

Thanks for letting me know that I could write something like that in the configurations! I wasn't aware of a loss_rate argument.
I guess I could leave it alone for now, since it inadvertently simulates mass loss, and besides - unlike H2 or O2, it doesn't just undergo a reversible thermal fluid/gas state change, it actually chemically reacts away. It's already got comparative advantages with hydrazine: less efficient, but with more thrust. Peroxide is supposed to be able to decay at any temperature (obviously, heat accelerates the process; actually, I'm wondering now if one could make the value a formula - e.g. loss_rate = temperature * x). It's thermodynamically unstable. It can also be catalyzed into decaying. Plus, what's interesting is that it decays into water and oxygen (2H2O2 >>> O2 + 2H2O), which means that a tank filled with peroxide can be turned into a tank partially filled with drinkable water and a pocket of oxygen. That has some interesting implications for manned spaceflight: you could have a fuel tank which is mostly used for a, let's say, transplanetary injection burn, and then you catalyze the remnant of the fuel; afterwards, the crew could open up a hatch and enter the tank, "wet workshop" style. The oxygen is breathable and the water is drinkable.
