Request Any SLS and Orion MPCV in development?

[gattispilot]

So what happens?

 

[Astro SG Wise]

also, I couldn't get to orbit with the RNS.

---------- Post added at 01:53 AM ---------- Previous post was at 01:52 AM ----------

Basically, all it does is freezes. It wont even load the graphics. Oh, by the way, I am surprised at how well the SLS launched that heavy RNS, but it still does not get to LEO.

 

[gattispilot]

So you load the scenario. Switch to SLScore and engage the thrust and then switch to the tower. hit the space bar and then press Launch. Does the rocket rise up. and then boosters fall off.

Skylab II

 

[Astro SG Wise]

No. The RNS scenario launches, and everything works in sequence, it's just to heavy for the EUS to get it into orbit. Referring to what happens on the SLS130_Orion_LTV scenario, the loading page is open, then it turns wight and says "This program has quit unexpectedly. Windows is trying to find a solution to the problem. . . "

Nice Skylab II by the way. When will you be done?

 

[gattispilot]

So has any else had issues getting a vessel using the SLS into orbit?

It maybe the RNS is too heavy?

Thanks on the Skylab. Not sure I haven't gotten the panels to fold down.

So do we to ramp up the EUS specs?

Since it is all CFG based anyone can change the specs.

So on the LTV scenario. Nothing in the log? Like a missing mesh or cfg?

Is there a stat on how much SLS can lift? Then we can see if there is a problem by comparing the RNS weight with SLS net payload weight.

---------- Post added at 05:15 PM ---------- Previous post was at 05:14 PM ----------

Right at the top, it says the modules. No mayfly, but I did install it... strange...

 

[gattispilot]

Odd the mayfly make the fairing disappears.

I have this for the EUS:

Mass = 11854 ; empty mass [kg]
MaxFuel = 107328 ; max fuel mass [kg]

sls core:

Mass = 85270 ; empty mass [kg]
MaxFuel = 894178 ; max fuel mass [kg]

interstage:
Mass = 5000

mass of RNS
Mass = 155705

 

[Astro SG Wise]

So, I will do some simple arithmetic if no-one has yet. Is the mass of RNS 155705 lbs, or kg?

---------- Post added at 09:35 PM ---------- Previous post was at 09:27 PM ----------

So, I went through some research and derived that the 70 ton SLS should weigh about 5.5 million (including the adapter and EUS most likely), so, I added what your max fuel weights were plus two shuttle srb weights and it added up to around only 4 million, more specifically, 3,606,506 kg. It should be able to take the RNS if it is only 4 million and the measurement for the RNS is in kg.

---------- Post added at 09:36 PM ---------- Previous post was at 09:35 PM ----------

Rephrase, if the RNS weight measurement is in lbs.

---------- Post added at 09:41 PM ---------- Previous post was at 09:36 PM ----------

Wait, we might be in trouble! Just read a statistic from NASA...

Height = 321 ft
Weight = 5.5 million lb
Payload = 154,000 lb

That's brushing it close if the RNS is 155,705 lbs!

 

[gattispilot]

It is in KG

 

[Astro SG Wise]

Your weights seem to be fine. Maybe it is the thrust power?

 

[gattispilot]

For the EUS:

Mass = 11854 ; empty mass [kg]
MaxFuel = 107328 ; max fuel mass [kg]
Isp = 1381 ; fuel specific impulse [m/s]
IspSL = 1381

MaxMainThrust = 440000

core:

Mass = 85270 ; empty mass [kg]
MaxFuel = 894178 ; max fuel mass [kg]
Isp = 4430 ; fuel specific impulse [m/s]
IspSL = 3563.12

MaxMainThrust = 7440000

 

[Astro SG Wise]

Now, I am no genius, and I don't know what IspSL really means. Is there anyone else that you know who would be able to find out if the correct equation to figure out if yours is the same as the real SLS? I can't find out how much thrust it actually has.

[orbitingpluto]

I helped gattispilot out with sorting out those configs, so I'm partly responsible if the numbers are wrong. I'm reasonably sure they're right, but I wouldn't mind someone double-checking things.

IspSL simply means Specific Impulse at sea level, and Specific Impulse is a way of measuring how efficiently a engine(jet or rocket) can use propellent to produce force. Orbiter measures Isp in m/s, and you should keep that in mind since the most of the world measures Isp in seconds.

Now, I do know where the problem with the RNS scenario is, and it isn't the rocket. Politely put, it is user error: The RNS comes in at ~150 metric tons, and the SLS version used can lift only ~130 mt. Don't feel too bad Astro, we all have moments like this, or at least I do. I have a easy solution handy, and it's simply reducing the amount of propellent in the RNS before launch so it masses something like 120 mt. Those 10 tons you didn't use for payload will be your margin for error, so you will have a more than excellent chance of getting the RNS to orbit.

Good luck on the RNS launch:thumbup:

 

[gattispilot]

I am going to be away for a couple of days. But I would just adjust the propellant level in the scenario.

RNS:RNS

[Astro SG Wise]

Ok. Thanks. I'll probably be testing it.

---------- Post added at 02:55 AM ---------- Previous post was at 02:43 AM ----------

Just tried scenario with new propellant level. Still too heavy.

 

[orbitingpluto]

I did a bit of math and my figures say that the RNS gattis gave you should mass ~127 mt- which should be doable under the published SLS specs. I could guess at why, but in absence of a firm idea I'm just going to point you to something that should have better odds of making orbit. New ship entry below:


RNS:RNS
STATUS Landed Earth
POS -80.6745292 28.5191812
HEADING 0.00
AFCMODE 7
PRPLEVEL 0:.7
NAVFREQ 0 0
XPDR 466
MODE 1
SOLAR 0
LAS 0
END
END_SHIPS

I took the propellent loading down from .8 to .7, which should leave the RNS at ~116 mt gross mass. It should work now; If it doesn't,and even if it does, I think you should post the following values from your OrbitMFD so I can get an idea how it went:

PeA:
ApA:
Inc:


Don't forget to set your reference frame to equatorial(press the FRM button) and change the display off of radius(DIST/RAD button).

 

[Astro SG Wise]

Ok. In terms of how the mission would go, one could just fill the RNS with 3/4 fuel or something and then send up a fuel canister to max the fuel before sending up the mars stack. Anyway, I'll get back to you on that. It might be my failure of flying, but I don't think that's it. Who knows. Do you want me to post my PeA, ApA, and Inc at my apogee?

---------- Post added at 01:01 PM ---------- Previous post was at 12:20 PM ----------

I just looked at the jumbo tanker.

[ame="http://www.orbithangar.com/searchid.php?ID=3105"]Jumbo Tanker v1.0[/ame]

Does it fit in the SLS?
If not, one could use the Space Tankers 1

[ame="http://www.orbithangar.com/searchid.php?ID=4350"]Space Tankers, release 1[/ame]

The purpose of the refueling mission would be that you could carry the RNS into orbit, re-fuel it, then put the habitation and other vehicles on it.

 

[Interceptor]

Hey John is there any chance you could include your version of the LER for the moon missions?

 

[Astro SG Wise]

That is actually a good idea Interceptor. I tried to use the [ame="http://www.orbithangar.com/searchid.php?ID=4659"]Small Vehicle Containers[/ame] . . . You could try them if you like. I am not sure if it fits inside the Block II though.
