AeroBraking Help #14

Closed pops64 closed 5 years ago

pops64 commented 7 years ago

So I am trying to aerobrake around jool. My altitude PE is at 106km which is defiantly inside the atmosphere but according to Mission Architect, It says it can't plan the aerobrake because I am not inside the atmosphere. I was wondering if I am doing something wrong or is they way I have setup not designed to calculate this. If you would like I can upload the .mat file for the plan. I have tried adding a coast after PE using a delta T and Next AP neither worked. Tried moving the aerobrake before Next PE Thanks for this tool made my cheap rocket designs easier to plan untitled

P.S Sometimes it will do it but when I go to change it because the AP is not around where I would like it then goes back to this. Aka 106 PE was working and give me a AP of 206km but when I bump the PE up it no longer works

I will close this out. Was able to getting working. I needed a Coast to Jool's SOI after the Sun SOI

I am opening this because there seems to be some magic value that has be in certain range in addition to just the altitude in order for it not to skip the aero brake. I was wondering what this has I can't seem to figure out what value it could be any help be great thanks. So it seems the eccentricty has to be less than 1 or AP has to be in SOI of the planet and tru < pi . Though I don't know what tru is referring to. If iIt would be possible if theses conditions can't be meet to create an aerocapture event. Thanks
