  thanks for testing liquid engines! I'm playing on Vulcan and want to make my first rocket run on liquids , not that hard to cool down with cascade phase change setup, the trick is to not cool the entire thing from cold end but just pump it trough each stage and gradually cool it until it reaches the cold end temperature. got about 6k litres of liquid volatiles and 50k mols of gas oxygen that I haven't started to cool yet.

  You can build it however you like. There is not a lot space in the rocket, so I like to put in the larger pieces starting from the bottom with the fuel tanks trying to visualise where all the pipes and cables will be going. Things like avionics and datalinks can fit into any little gap you have left.

  Are multi-stage rockets possible? High power to get it off the launchpad and then better efficiency for the space travel. perhaps by putting 3 tanks in it and then using a chip to switch between NOS and O2?

•

  Multi stage is not possible. Typically IRL better efficency means less thrust. Here you get better effiency and better thrust so there is no benefit to having multiple engines.

  And BTW the temperature matters even for liquids becouse the ratio of liquid moles per gas moles is higher at lower temperature. I guess the liquid engine only uses or prefers liquids so gas won't be used in the engine but it adds weight to your rocket you don't want to carry around all the time. For expansion I thing the game does not work correctly and increases volume of warmer liquids compared to colder once but I could be wrong. Anyways that wouldnt change much cause the difference is sooooo small.

  Those are the values I got as well. 72.7% for vol-oxygen fuel and 60.6% for Vol- Nitrous fuel. Being able to get 31kN of thrust on a fairly simple rocket (compared to pressure fed at least) is really hard to beat. I'm interested in seeing your approach to pressure fed liquid rockets and see if you can get a fairly stable thrust. I'm on my 4th revision pass on the controls for mine... Had a few accidents though. Apparently liquid fuels just combust when exposed to air... doesnt make much sense to me but oh well.

  I did spent two hours in creative to receive the following mole per volume data for the Pumped liquid engine fuel tank ratio. These are for the coldest possible temperature before it starts to freeze and ment to be use for calculating the volume of liquid tanks you need for volatiles and n2o so that you can aim for equal mols becouse the perfect mix is 1mol to 1mol: VOLATILES 7kpa at -191°C Mol: 23,9 liquid 0,398 gas Volume: 0,955L => 25mol per liter (only the liquid part) (5kmol = 200 Liter 10kmol = 400 Liter 12500mol = 500 Liter 20kmol = 800 Liter 25kmol = 1000 Liter 31250mol = 1250 Liter 50kmol = 2000 Liter 62500mol = 2500 Liter) NITROUSOXIDE 810kpa at - 19,9°C Mol: 97,6 liquid 14,4 gas Volume: 2,54L => 38,4mol per Liter (only the liquid part) (5kmol = 130 Liter 10kmol = 260 Liter 19200mol = 500 Liter 20kmol = 520 Liter 25kmol = 651 Liter 31250mol = 813 Liter 50kmol = 1302 Liter 62500mol = 1627 Liter) Hope it helps you if you were curious about the correct ratio for your tanks without just guessing and testing how much of n2o or volatiles is left after your flights.

  Ultimately setting up filtration will probably do you best for the space ice so you don't have to try get stuck with some gas in the system. If you're gonna be stuck doing it, you may as well integrating to pull volatiles off your water system as well. The combustor changed on the 26th: Changed H2Combustor throughput to be like the Filtration machine. It has a slow base through-put rate which can be increased by maximising the pressure delta between input and output pipes. So now you need to put a turbo pump off the combustor to make it more efficient.

  Good luck with liquid rockets. I’m sure you want to find the settings and stuff out yourself through mathing. But if it helps, take into consideration how many mols are in a liter. You still need a 2 vol : 1 oxygen molar ratio or a 1 vol : 1 nos molar ratio. The pumped liquid engine you can have two separate tanks and the setting denotes how much it pulls from each input which i presume has a fixed rate but seems to pull only liquids. There is a perfect setting for both fuels to get your max thrust. As for the pressure fed rocket you would need to premix your fuel or have the ability to mix your fuel inside your rocket. Again keeping in mind the molar ratio of the two but since you want high pressure for max thrust, this will probably throw off your mix depending on how you do it. It’s quite a challenge and i suppose i am curious how you will tackle it. I will say of the two liquids, oxygen becomes your pressurant gas for the two and while the liquid pressure fed rocket does accept gases, it doesnt seem to accept it in a high enough amount that nitrous fuel in a pressure fed rocket is not very usable.

•

  51:05 Instead of "learning how to mix rocket fuels" via different pressures, you could learn that the liquid rockets Setting variable changes the input rate between the two inputs, allowing you to set both inputs to the max applicable pressure and still get the correct fuel ratio mix in the engine.

  The CO2 canister exploded due to the room temperature being at 25C and the CO2 evaporates at -8C~ So the temperature in the room caused the CO2 to evaporate and overpressure the canister. Also why don't you just use a gas sensor to monitor ambient temperature to turn the air vents when temperature is <-35C?

  "Lets take a shower". *Proceed to jump into pile of poop* ... and didnt took a shower at all Jokes aside, whats the reason you keep pressure only at 40M instead of cranking it up to 59 (or whatever the limit is today)? You added 10% more pressure and you got like 20% more thrust. Imo the closer to the pipe limit, the more effective output it will produce. If for some reason dont want to keep it powerfull during most of the flight, you could at least crank it up during landing to increase thrust. Actually, if landing doesnt look good (like last time), you could even go past the limit for short period of time. Damaged pipe is better outcome than crashing and theres no way you wont have enough thrust with pipe cranked to maximum.

  Mick - I have been doing some research on this Pressure Fed Gas Engine you are using and came across something interesting about it. The engine has 2 pipe inputs which leads me to believe you may not need a fuel mixing pump at all since it might be built into the engine itself and possible controlled through the uplink. Or is automatically adjust depending on exterior pressure condition. I also, watched another video using this type of engine and that rocket had no fuel mixing pump at all.
