    Apollo 13 Launch Scenario: What should I expect?

    I can check into that hot fire later today

    Apollo 13 Launch Scenario: What should I expect?

    When I looked at your save, the MNA values are what I copied to generate those MNB values.

    Apollo 13 Launch Scenario: What should I expect?

    In any case, the fuel cell shouldnt have thrown a NaN (kind of a divide by zero state) so anything helps us look into it.

    Apollo 13 Launch Scenario: What should I expect?

    Would you mind sharing the save before the NaN? I can see if it was procedural (ie not getting the FC off the bus) or if there is something else going on. Also the test meter is wired incorrectly, those injector temps only need the INST power to generate a signal, so thats on our end :P

    Apollo 13 Launch Scenario: What should I expect?

    Yeah looks like something got screwed up way back when, your main bus tie is still "tied" to fuel cell 2 and it has generated NaN values, so nothing can power up properly through the main busses. Could you humor me and dig back through your save files and find where your fuel cell 2 went to...

    Apollo 13 Launch Scenario: What should I expect?

    Something is screwy with this save it seems, I need to dig a bit more, but you should have power in MNA and MNB. I will report back. Also I see in the save there are a few NaN's which is a computation error (not your fault.)

    Apollo 13 Launch Scenario: What should I expect?

    I will check out the save and see. Actual LM lost Bat 2 due to a short as it is :)

    Apollo 13 Launch Scenario: What should I expect?

    I could be way off here, but it seems injector temperature data is only powered through the instrumentation bus (V1 and V2 busses) not the SCE/FLT BUS. I need to do some digging but our modeling could be wrong here haha!

    Apollo 13 Launch Scenario: What should I expect?

    Are you sure you should be able to see the injector temps at that point? If you can give me a mission time that you are currently following along with I can backtrack.

    Apollo 13 Launch Scenario: What should I expect?

    Sounds good, I actually have improvements for the injector temps in an update coming up, so you might notice them a little cold compared to how they were in the mission

    Apollo 13 Launch Scenario: What should I expect?

    I am referring to this TM procedure which was used to read, among other things, the systems test meter. Also no save was attached to the last post :P

    Apollo 13 Launch Scenario: What should I expect?

    Likely something missed in instrumentation or signal conditioning, those provide the power for those signals. Check the TM powerup procedure for anything missed.

    Apollo 13 Launch Scenario: What should I expect?

    5C-D and 6A-D? The test meter should work for those 6 injector temps, are you getting it to work for any other indications?

    Apollo 13 Launch Scenario: What should I expect?

    Yeah pretty much :) I dont remember if a "start time" of sorts was padloaded, but a fresh LGC start even under normal circumstances had a useless time, so it would be set via the CMC (and then a V55 used to correct the initial error by pressing enter on both at the same time on N65)
  15. rcflyinghokie

    Apollo 13 Launch Scenario: What should I expect?

    V55 has nothing to do with MCC access to the clock, so that comment is incorrect. V55 simply changes the current time by incrementing it to null any error between its current time and expected (correct) time. This was done because they couldn't uplink, but they could see the current LGC time and...

    Apollo 13 Launch Scenario: What should I expect?

    Yeah they didnt mention it to the crew, so I am guessing its implicit. So i would ship up a clock update with your state vector and REFSMMATs
  17. rcflyinghokie

    Apollo 13 Launch Scenario: What should I expect?

    I think the clock is stopped on the LGC when the cb is pulled, but I am not 100% sure. However, looking through the mission control transcripts, during the uplink of the REFSMMAT's and SV, they mention in passing "we have a good clock update" so that might indicate a clock update was shipped up...

    Apollo 13 Launch Scenario: What should I expect?

    I am looking into the clock now, I will report back. Also, regarding the checklist with the quad heater cb randomly in, it actually was correct due to it breaking before launch: 135:35:20 Haise: And, Jack, you can tell Owen Morris that the RCS System A/B 2 Quad 1 breaker is still nicely in...

    Apollo 13 Launch Scenario: What should I expect?

    Correct, I will elaborate in the next answer. The first one is an actual REFSMMAT based on the known alignment of the spacecraft (the one AGS is body axis aligned to) where the sun and earth were in the AOT. Then the desired REFSMMAT was a P30 REFSMMAT for MCC-7 burn. A 400+3 was performed to...

    Apollo 13 Launch Scenario: What should I expect?

    As I mentioned previously, we currently don't have a model for reverse power flow, so you cannot charge the CM bats using the LM power. You will have to manually edit the scenario to top them off.
