egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…
<queqiao->
⟨__waverider⟩ when I manually do it its also off
<queqiao->
⟨__waverider⟩ because of this ive never had a successful lunar transfer in Principia
<queqiao->
⟨__waverider⟩ I can do the planning part
<queqiao->
⟨__waverider⟩ I have the required understanding of orbital mechanics
<queqiao->
⟨__waverider⟩ but gosh the timing is bad
<queqiao->
⟨__waverider⟩ I have the required understanding of (basic) orbital mechanics
<queqiao->
⟨test_account9540⟩ If you mean never had a successful moon flyby then something like in that video a several times harder. Need to learn moon flyby first
<queqiao->
⟨test_account9540⟩ * is
<queqiao->
⟨__waverider⟩ ive done lunar flybys with principia before but Ive had to save and reload like 50 times to get the timing on the burn right because nothing that the game tells me is correct
<queqiao->
⟨__waverider⟩ is there any way to counter the innacurate manuver nodes?
<queqiao->
⟨__waverider⟩ * inaccurate maneuver
<queqiao->
⟨test_account9540⟩ How so? You get into the parking orbit, plan the TLI in principia, execute the maneuver (AFAIK J can do it for you), make slight corrections with RCS if your probe is hopefully guided
<queqiao->
⟨test_account9540⟩ Stock maneuver nodes are not used at all with principia
<queqiao->
⟨__waverider⟩ I use the principia flight planner
<queqiao->
⟨test_account9540⟩ How so? You get into the parking orbit, plan the TLI in principia, execute the maneuver (AFAIK MJ can do it for you), make slight corrections with RCS if your probe is hopefully guided
<queqiao->
⟨test_account9540⟩ so what's the issue?
<queqiao->
⟨x3rcesblue⟩ Does principia consider testflight engine failures in its trajectory calculation?
<queqiao->
⟨test_account9540⟩ No
<queqiao->
⟨test_account9540⟩ Or do you mean failures that already occurred, so you have some engines and some bad engines? I suppose you should just switch off the bad ones.
<queqiao->
⟨test_account9540⟩ +good
<queqiao->
⟨test_account9540⟩ Not sure about the weird case of partially broken engine that has lower thrust or isp but works 🤔
<queqiao->
⟨x3rcesblue⟩ In my case I have one engine that has suffered thrust loss
<queqiao->
⟨test_account9540⟩ Try enabling only this engine, planning a maneuver, then disabling it and enabling a good one and planning again? Will the burn time be different or the same?
