Hello,
I am having an issue with the Metallic Hydrogen engines, Specifically GX-220. I have KER installed and it will state a certain TWR and delta V. if I calculate the values, KER values match what is expected. For some reason the stock game's staging menu only states like 1/5 values for TWR and Delta-V. Is there a way to fix this issue?
Thanks!
Edit: I did some math this morning. Turns out that KER is looking at the Metallic Hydrogen ISP of 1700, not the combined ISP. I figured this out by changing the MH ISP to 1034s and that ISP showed up in KER menu. but then the engine only performed at the mix of 1034 and 400 which is incorrect, so I changed it back. Not sure how to fix that in KER so I just wrote up an excel file to calculate the values to fine-tune my numbers. Still not sure why the KSP program is giving a small TWR but maybe its only looking at the Liquid Hydrogen Thrust? luckily, the actual TWR is used not the value shown in the stock menu.
If anyone know how to change the KER file to look at the correct ISP that would be helpful. Otherwise, I will just use what I have now.
