7 years ago I'll take on LH2 + LOX, and possibly more.
I wrote a quick little Python script to extract relevant data from text files generated by RPA:
from os import walk
files = []
for (dirpath, dirnames, filenames) in walk('./data/'):
files.extend(filenames)
break
data = []
OFratio = None
for file in files:
t = []
with open('./data/' + file) as f:
for i, line in enumerate(f):
if i in [15, 24, 25, 31, 34, 39]:
t.append(line.split())
OFratio = t[0][2]
Pc = t[1][1]
Tc = t[2][1]
Te = t[2][4]
Pe = t[1][4]
MW = t[4][4]
gamma = t[3][4]
Mach = t[5][5]
data.append([Pc, Tc, Te, Pe, MW, gamma, Mach])
if len(data) < 15:
print('[WRN] Less than 15 keys!')
block = ''.join(['MixtureRatioData\n{\n OFratio =', OFratio,
'\n PressureData\n {\n',
''.join([' key = {}, {}, {}, {}, {}, {}, {}\n'.format(*line) for line in data]),
' }\n}'])
with open('results.txt', 'a') as f:
f.write(block)It assumes you are saving the generated text files in the same directory as the script, named data.txt. It will append results.txt with a new line each time it is run. Only run it once per set of data.
There is an up-to-date version of this script and more info in issue #3!

The options that this project are based on how many propellant mixtures we have to work with. If you'd like to help, please check out the WIP propellant config tutorial.
If there is something you're interested in working on, please comment. These configs are a lot of work and I would like to avoid duplicating work if possible. Once you begin work on a mixture config, please make an issue for that mixture and link it below, so that things can be organized well.
So far we have 3 necessary configs that need to be completed:
With these completed we will be able to create a reasonable simile of every in-common use engine that has flown.
There are several uncommon propellant combos that we can use that aren't in common use that would also be nice that the above 3 combos can not stand in for. They are, in order of desirability:
There are several other combos (mostly hypergolics) that would be nice to have but are sufficiently similar to UDMH + NTO that I won't list them here as they aren't a priority. If you've got some weird love for one of them, I'll still accept the configs, but there are higher priorities.
