Real Fuels Propellant Mixture Converter V 1.4 (Feb 13th)

[Zander]

Hello,

Since NathanKell released real fuels you can now create real life fuel combinations for your rockets. To do this you have probably consulted technical manuals and NASA press kits. But in them you will probably find the ratios given by mass, the fuel amounts given by mass the total propellant burned per second but not the breakdown of how much fuel and how much oxidizer. You may need to figure out what the isp of a certain mass flow rate is or the volume mixture ratio which ksp uses when you only have the mass mixture ratio. For these problems I have created a program which will do all the calculations necessary for filling fuel tanks with real life amounts, Configuring engines to real stats and more.

Its simple to use, just input the propellant mixture information that you have (you need to enter the density of your propellants (kg/L) and one of the 2 ratios,mass or volume as 2 percentages in decimal form, ex: .50 ox .50 fuel ) and you can then use the selector to choose a value for total propellant mass/volume, fuel mass/volume, oxidizer mass/volume, and max thrust it will do the calculations for it.

please let me know if you want other calculations added to the tool or need help using it.

Since version 1.0 There are now selectors with different fuels and oxidizers you can select with the densities preset.

but you can also choose new fuel and new oxidizer to add your own

V.5

First release

V 1.0

-Updated to include oxidizer and fuel selections with preset densities

-Limited values to 1 trillion to prevent stack overflows

-prevented setting the ratios to numbers over 1 or under 0

-prevented imputing negative values

-added zeros to all decimal numbers for neatness

-fixed issue where user could type in the selector boxes

V 1.1

-Fixed bug where changing the selector would set all values to 0

-Fixed bug where ratios couldnt be entered

V 1.2

-Fixed a bug where densities couldnt be manually entered

-reset all other fields to 0 when the densities are changed

Known issues: when using liquid hydrogen changing the other ratios in a way that makes the hydrogen mass ratio very low will cause it to appear as 0 due to its very very low density and ruin the other calculations by making them divide by 0

This is fixed by adding a few more digits to the ratio you changed

ex: changing .76 to .760001

V 1.3

-fixed bug that prevented the user from entering values if they didnt add a 0 before the decimal point

-fixed bug that prevented the user from entering values if they did add a 0 before the decimal point

-fixed bug where user could not enter ratios smaller than 10%

Known Issues: Liquid hydrogen ratio bug.. See V 1.2 changelog for getting around it.

V 1.4

-Fixed Liquid Hydrogen Ratio bug

-Fixed a problem where adding a 0 to an entered value wasn't triggering a recalculation

Sorry I should have explained. click the link then just click "Download this file" and type in the captcha. It will start the download.

heres an image of the site with it circled in red in case you still cant find it.

Everything works,great program! Thank you!.
