He should know if the the orbiter had an angle when mated.
Please ask, as it's much better to hear it from the "horse's mouth" than us here trying to guess.
I'm sure there were some tolerances (like 0.0 +/-0.1), but the "normal" angle is what we need.

I have sent the message with the question. I'll relay anything worthwhile.

Can someone verify the math in this post on the NASASpaceflight.com forum by Fequalsma: https://forum.nasaspaceflight.com/in...722#msg1853722

1.1s sounds a bit much.

The math is OK. It assumes we want to calculate the angle between the attachments, which is not what we need...
We need the angle between the axis of the OV and ET.

Can't that be calculated from the angle between the attachments? They're where they are, that doesn't change. And the orbiter axis doesn't change, it's still level with everything, it's just that the orbiter has a slight positive AoA when mated to the ET. Obviously Enterprise never had any issues with the 6 AoA used for the ALTs.
And the shuttle GNC could easily sense the slight AoA as the reference plane never changed.

That assumes that the attachment points in the OV are leveled, which they aren't.

These 2 sentences contradict each other. If the axis are leveled, there is no angle.

The Enterprise wasn't controlling the mated flight...
I conceed that there may well be an angle in there for aero reasons, but I want to confirm it really exists before I change tons of code. "3D models don't fit" isn't enough evidence for this, especially when there isn't a single bit of info pointing to some angle existing in there, plus there is info saying the axis match, plus it would make GNC harder.

I just committed a scenario to run TAEM at Edwards. It should allow all TAEM and A/L trajectory options to be "exercised". FCS is (still) "wonky", so although most guidance references are correct*, they might not be followed perfectly.
Tons of things are still missing from the displays, others need fine-tuning. I'll work them after Entry guidance.


*) Some parameters are "stock" so the whole thing might not fit perfectly, but it gets to the runway. Also, TAEM has several requirements, so you might see e.g. altitude diverge for a while, but that is to correct Qbar or E/W. PRFNL roll has a small issue... I'll track that down later.

The Enterprise wasn't controlling the mated flight...
But she was active unless you think she was rapidly powered up following separation from the SCA. Only during the Captive-Inert tests was Enterprise powered down, essentially mimicking a ferry flight. Starting with the Captive-Active Tests was she fully powered up and had a crew onboard.


So just to clarify here: What we need to know is the orbiter had any AoA when mated to the ET?

Yes, the vehicle was "on", but wasn't controlling the flight, i.e., "go up", "turn that way", "more thrust from the jet engines", etc...

Pretty much. I'm sure there were tollerances and also things changed as the ET shrunk during tanking, and then expanded again in flight, but in the end we need to know what is the default or standard positioning of the OV in relation to the ET. IMO, all bits of info so far point to them being fully aligned.

Any "experts" here on M50? I was adding the ECI and ECEF code to UltraMath and noticed this:
Code:
const double AXIS_TILT = 23.4458878*RAD;
Decided to cross check with the value Earth.cfg and they don't match...
I didn't check where the code is used, but it should be in the OrbitDAP. If nobody knows if changing the value is good or bad, I'll just create a ticket so it doesn't fall thru the cracks.

Could be correct. W50 uses Epoch B1950 = 1950 January 0.9235 TT, J2000 (Orbiter) uses epoch J2000 = January 1st, 2000 12:00 TT


It should be 23.439281 today. Still researching an exact measurement of 1950...

Here is the source of the axial tilt value, BTW: https://www.orbiter-forum.com/showthread.php?t=981

Thanks!
That's another thing I'd like to see done: a finished/fixed OrbitDAP so we can point whatever part of the vehicle to whatever part of the sky or Earth.

Default Problem with the Launch Pad

Hello,

I created my own test scenraio with SSU v5. It contains 2 Shuttle on the launchpads (LC39A,LC39B). Everything is configured for one shuttle launch, I mean one is going to fly and the other stays on the ground.

The scenario is working almost normal. But the RSS door of the Launchpad is closed at T-10min, and the clock is stopping at T-4min.

There is a pictures about my double shuttle configuration:


And the pictures of the RSS door at T-4min:


this is the scenario file:

Still tons of work to do, but the new entry guidance just flew the first reentry without killing the crew or destroying the vehicle!
Continuing on to TAEM and A/L, and I just went from orbit (or EI at least) to the centerline of the runway in AUTO!
I'm so happy right now that I'd post an image of the landing, but the OV model is still all messed up on my end...

Which, I'm pretty sure, is the source of some animations being messed-up. There is also the mapping to finish.

Some interesting paper with maybe small implications for our GNC work:

https://ntrs.nasa.gov/archive/nasa/c...0110003998.pdf

The Shuttle used both kinds of star trackers at the same time later, because of problems tracking the ISS with the newer solid state trackers (as the ISS was too bright)

One conclusion of it: we should make the installed star tracker type a mission file option. There had been some experimentation during the ISS assembly missions and the Orbiters launched with different star tracker configurations.

(And we should make spare parts limited. For being pure evil.)
