Guest Posted July 14, 2019 Share Posted July 14, 2019 The problem with a 0.625m engine is that there's nothing out there to base it off. The only engines which might be that small are Chinese YF-73 and YF-75. Not only are they used in clusters anyway, good info on them (including exact dimensions) is scarce. @Nertea Splendid work on the engines. Just make sure not to overdo the blue. I think the way it's currently done is just right. Can't wait to try those out in combination with NFLV. Quote Link to comment Share on other sites More sharing options...

New part names, I want to be able to be a bit flexible with dimensions. 17 hours ago, KSPrynk said: I'm loving the detail (and holding my breath on the RAM impact). Looking forward to this update. Shouldn't be... awful. Maybe 2x the current footprint at most, but you will get more models 17 hours ago, KSPrynk said: Also, any 0.625m LHO engine in the works, comparable to the KA Eel? Small craft and probes could use some cryo love... If there is space on the relevant texture sheet I might do the RL-10-A5 as a small thing. We'll see. Also I did a really stupid thing and accidentally triggered a release for a WIP thing. 0.7.0 is not a thing. I will roll it back when I can but it's less easy than I'd hope.

Some more update on the revamp: This is the all-new Stromboli, a tiny sustainer-type engine based on the RL-10-A5 developed for the DC-X program. It comes in 0.625m boattail, 0.625m ring and compact variants. Next up is the Hecate, which replaces the Chelyabinsk. It still has the extensible nozzle and is based on the RL-10-B-2, everyone's favorite kitchen appliance. Continuing with the new Pavonis, a 1.875m vacuum engine based roughly on the RL-60 engine. It comes in ringed and compact variants and also has an extensible nozzle. The Pavonis returns as a cluster in the Tharsis, which replaces the Yucutan engine. It comes in 3.75m and compact variants. It keeps that handy extending nozzle. Quote Link to comment Share on other sites More sharing options...

It's far too expanded, the nozzle on the real thing has a completely different profile: Is that shape doable, or would it hopelessly distort the textures (I assume there isn't much room left in the atlas)? If not, don't worry too much, though. The real engine, with its expansion ratio of 4.3, is firmly in the booster class. A sustainer would, presumably, have a nozzle closer (though maybe a bit narrower) than what you modeled. Quote Link to comment Share on other sites More sharing options...

Spagoose Posted July 20, 2019 Share Posted July 20, 2019 (edited) I'm hoping someone can explain how to best use these engines. I have unlocked the Volcano, but can not find an instance where it is better than the Swivel or Reliant engines. If I make a basic ship with just a command pod with a fuel tanks and and reliant engine, it weighs 4.4 tonnes with 1820m/s dV, while if I use a ship with the Volcano engine with 2 LH2 fuel tanks, I get a ship at 5.3 tonnes with 1583m/s dV. I have experimented with various amounts of fuel and at no point was the Volcano worth using. I can only assume I am doing something wrong, so could someone shed some light on what is going on? Do I need to remove some oxidiser? Edit: So apparently I need to change the LH2/Oxidizer ratio, what is the best way to balance this properly?

These types of engines are best used as upper stages with far more dV - since they have more isp and LH2 is bulkier but lighter, the upper stage will be lighter. In turn, that means you can use smaller boosters to put it in orbit. But yes, they are a bit of a niche engine. I sometimes use them for ore tankers as well.

They're bad if you want to save on size, but the fuel is rather light. So while the tank for the same amount of deltaV would be larger, it would be far lighter.

Here are a couple of recent posts. Two more engines have been completed this weekend, leaving only one. This is the Fuji, a replacement for the current Odin. The Odin was based on the LE-7, which is now the Skipper in Restock, so I've used its successor the LE-9 as inspiration. The Fuji comes in Compact, 2.5m and boattail variants. The Mars is being replaced by the Etna. It's effectively the same though, still based on the RS-68. It comes in Compact, 3.75m and boattail variants.

Nertea Posted July 22, 2019 Author Share Posted July 22, 2019 Ok last one then we can sleep, the Ulysses, replaces the Tunguska, based on the J-2X (real one, not that silly other one @CobaltWolf dug up ).

rhoark Posted July 22, 2019 Share Posted July 22, 2019 Can anyone confirm stock fuel cells can run with H2/oxidizer? They show me a button in VAB to select fuel type, but in flight they do nothing when set that way. I hesitate to say there's a bug or if its just me.

There shouldn't be a select button or anything, just new 'start fuel cell' options with LH2. Maybe a mod interaction? Quote Link to comment Share on other sites More sharing options...
Nertea Posted July 26, 2019 Author Share Posted July 26, 2019 (edited) Holy enormous update batman! Check out the beautiful update gallery, with screeshots courtesy of @Zorg and @Rock3tman_. CryoEngines 1.0.0 Updated B9PartSwitch to 2.8.1 Updated DynamicBatteryStorage to 2.0.2 Added support for GenericFieldDataHandler - a simple plug and play handler for other mods to use Fixed FissionFlowRadiator adding heat to the simulation instead of removing it Fixed two instances of null reference exceptions when switching vessels/scenes Updated DeployableEngines to 1.1.0 Added new ModuleAdvancedLookAtConstraint module Version of basic FXModuleLookConstraint with the addition of viewing vector stability Tries (mostly successfully) to ensure a constrained object's up vector (green transform in unity) matches the up vector of the target object, which resolves problems with almost vertical/vertical gimbal pistons Same syntax for configs as FXModuleLookConstraint (see GitHub wiki for more details) Updated CryoTanks to 1.2.0 Fixed a localization typo Tuned VAB UI part tooltip fields for boiloff module Reworked textures of foil tanks to match Restock and Near Future Construction Normalized grey to be similar to all my other mods Recompressed all textures with better compression algorithm Added optional simplistic draft Liquid Methane support Slightly cryogenic (1/10th the boiloff rate of Liquid Hydrogen) Similar mass ratio to Liquid Fuel (9) Higher cost ratio compared to Liquid Fuel (0.12 vs 0.1) Enabled by declaring any MM patch with :FOR[CryoTanksMethalox] or including a folder in GameData called CryoTanksMethalox Soft-deprecated entire old set of CryoEngines parts; they are replaced but invisible so people have time to adapt New 0.625m engine: CR-10A 'Stromboli' Cryogenic Rocket Engine: Sustainer engine based on updated hypothetical DC-X RL-10-A5. 0.625m, Boattail and Compact variants Revised 1.25m engines CR-2 'Vesuvius' Cryogenic Rocket Engine: Sustainer engine based on Ariane Vulcain 2. 1.25m, Boattail and Compact variants. Similar to old Volcano. CE-10 'Hecate' Cryogenic Rocket Engine: Vacuum engine with extensible nozzle based on RL-10-C2. 1.25m and Compact variants. Similar to old Chelyabinsk. New 1.875m engines CR-0120 'Erebus' Cryogenic Rocket Engine: Sustainer engine based on Energia RD-0120. 1.875m, Boattail and Compact variants. CE-60 'Pavonis' Cryogenic Rocket Engine: Vacuum engine with extensible nozzle based on unflown RL-60. 1.875 and Compact variants. Revised 2.5m engines CR-9 'Fuji' Cryogenic Rocket Engine: Sustainer engine based on JAXA LE-9. 2.5m, Boattail and Compact variants. Similar to old Odin. CE-2X 'Ulysses' Cryogenic Rocket Engine: Vacuum engine based on Constellation J2-X. 2.5m and Compact variants. Similar to old Tunguska. Revised 3.75m engines CR-68 'Etna' Cryogenic Rocket Engine: Sustainer engine based on Delta IV RS-68. 3.75m, Boattail and Compact variants. Similar to old Mars. CE-602 'Tharsis' Cryogenic Engine Cluster: Vacuum engine cluster with extensible nozzles based on alternate Constellation upper stage option. 3.75m and Compact variants. Restock style engine effect model and emissives propagated to all new parts New plumes for all engines RealPlume support for new plumes, courtesy of Zorg Slightly tuned most revised engines in terms of mass, thrust and Isp compared to their predecessors CryoEnginesLFO Extras package has been tuned to match the new content (typically 70s of Isp loss) New Extras package: CryoEnginesRestock Adapts the appropriate ReStock and ReStockPlus engines into cryogenic engines (Vector, Mammoth, Rhino, Skipper, Corgi, Skiff/Caravel) with significant balance changes Changes the plume for the Rhino, Skiff/Caravel and Skipper to be appropriately cryogenic Hey look, I defined this as feature complete! This means new development is unlikely to occur. Because of the scope of this update, I do expect some bugs though, so report away! I'm also looking at adding optional support for LCH4 engines as you can see from the changelog. I'd appreciate any feedback the community might have for this in terms of mass ratio and volume ration - it is a fuel that is somewhere between LF/O and LH2/O in terms of volume and cryogenic properties.

The Vulcain/Vinci have very specific styles (nice symmetry and well laid out control gimbals), as do the JAXA engines (big pipes!) - compare with the chaotic pipe and wire messes that are Russian engines, and the less chaotic but still maze-like American engines.

Is that for NFLV engines, or are you planning new models? As far as RL engines go, there isn't much to add besides what you already modeled for NFLV, but there's just one you missed... the RD-0146. Or, more specifically, the RD-0146CH, which was RD-0146 converted to run on LCH4 (as opposed to LH2 of the original). It should also have an extendable nozzle (the first ones are concepts for the LH2 version, but it's close enough): While a Russian engine, the MYRA stage it was supposed to fly on (dunno if that's still the case) was for an upgraded version of the ESA Vega rocket. I would put it at the niche currently occupied by RS-18 in NFLV, while scaling the latter down to 0.625m (which would be more accurate, IRL it's basically an LMAE).
