- DGIII scenario - what ya think ?

[Shirson]

That's one option, or you could just have the DG-III save the Mir station before it deorbits. Say there are still
cosmonauts on board and the station debris may hit a densly populated area - whatever it may happen to pass
through the atmosphere.

Deja vu...
Default Orbiter scenario for Shuttle-A...

There, this sound a little better?

Yea. Big thanx.

Sound perfect now...

Tell me wen ready I'll open the new post and make change on the download page
as soon as you tell me that's ok.

Btw: I preffer to host your file if you don't mind so I can put statistiques on them (number of download)
that anyone can view. (and no problem to make eventuall changes: mail me new versions)

Watch this space in a couple of hours

Btw to all: don't forget that easy or common mission are welcome: reentry with path
already set, launch window for a specific trip (mars, venus etc etc)

oki doki

Download page updated and post created, any new scenario well packed
as the Shirson's one are welcome.... (this is a subliminic message

When there will be 3-4 scenario I'll make some advertisment in the
official forum.

Just added a new mission, "Explosion during ascent" hope you like it  (see DGIII scenario download)

I'll make another one right now  "Save this guys on phobos"  if I can.

Huh, good you mentioned the engine gimbal. What exactly do the different modes do?

In theory I know that the gimbal is used precisely for what you did in your scenario, to vector the thrust to
compensate for the loss of an engine. But what about if both engines are fine, can you actually use it to push the
vessel "sideways". Left/right up/down? Like, when you are pushing a load who's CoG is off the thrust axis.. Like Mir
for example? If you don't gimbal I assume you would slowly start to induce a spin, but if you gimbal the engines
correctly, you shouldn't? Can DG-III do that?

full of questions, eh?

Oh well I don't know exactly I never use them and they are "stock" button.

What I know is that in "MAN" you can use the slider to vector each engine
exhaust and with "comp" and auto it will compensate himself (see when you
press thrust key the slider goes both on the right automatically)

They are absolutely needed if you use thrust in this mission because you spin
immediattely and badly on the left without them.

And yes vector thrust in an ideal world could be used as real rocket to control
you ship instead of using the RCS. I don't know if an add-on take avantage of
this yet... I bet an autopilot that would control the rocket using only this
would be a bit tricky to do (well not impossible at all in fact, it seem to me
that the shuttle use it a bit for the ascent)

I think NASSP has the option on all vessels, even LEM, but I never tried landing with gimbal instead of RCS.

Shuttle only uses it for boosters I think... I could REALLY use engine gimbal with the Shuttle though. The OMS engines
are tilted upwards and when you change perigee/apogee you ALWAYS also change the plane, unless you tilt the
whole shuttle up by 15 or so degrees.

Hm....
In RCS using pair thrusters with oppose direction for spin and same direction for translation.
Rocket's centre of mass must lie on plane, formed by pair vectors of thrusters, or rocket starts spin and translate at
the same time.

Thrust vector of main engine traverse centre of mass too. Any deviate, and rocket starts spin and translate at the
same time  (like blowing balloon).

Am I right?

[DocHoliday]

the same time (like blowing balloon).

Depends how far to the side the main engines are (away from thrust axis). DG-III's are only slightly to the side, so
this spin would happen gradually, but if you were for example to use only one rotating engine pod of the Shuttle-A,
you would probably get a result like you said quite soon.

When one of the engines is out though, thurst vectoring enables you to keep the vessel stabile on just one working
engine even if it is off the main axis. Again, with a vessel whose main engines are far appart, the engine would have
to be able to gimbal quite a lot to compensate.

I know we're going increasingly , but did you guys hear about the 'phantom' Gyro-Saturation problem on
ISS?  EVA suits create small amounts of thrust (1 newton) which on long repair missions push the ISS enough to
saturate the gyroscopes.  Recently, the ISS's RCS thrusters had to kick in to re-stabilize.   (dangerously close to the
EVA crew)  Those must be MASSive Gyros!

Hey.. that could give someone a Scenario idea... possibly with even Sexier Results than Lost Love on Phobos!

[DocHoliday]

Okay, I am officially declaring a contest on the visual looks of Loraine Horn. Obviously, Orbinauts are just men and
might really be emm.. more motivated to save her?

A suggestion?



(WHAT?! I like Elven gals!)

Sure..... put off her clothes

[DocHoliday]

Too lazy you do it.

[DanSteph]

No problems:

[DocHoliday]

Hehe, nice! They both remind me of how Artemis is usually portrayed. The sexyest greek godess in my opinion

Ok, and Loraine is off duty now



PS: credits not mine but due of course.

Humph the poor girl is probably fed up of being seen solely as a sex object!
After all, to have made it as an astronaut in the male dominated arena of space exploration, she must have loads of skills,
brains and determination.

Well after the final sex war that took place in 2039 woman took the full control
of the society. I have heard that last years (2047) there was increasing reports
of bad treatment by some womans against their men. This is perhaps why nobody
want to rescue Loraine ? perhaps she's a bad mistress ?

(no I don't drink, I just have perhaps to much imagination.

Have you got women mixed up with robots again Dan?

lol

Actually 2039 was only the date that men realised women were in full control, they'd been quietly in control for
decades before that

[reekchaa]

I guess nothing makes mankind's roots sing louder than a good ol' scenario of 'Rescue the Women'  

Okay.. here's how the new scenario starts out...

"It seems your Boyfriend lost his keys again on Triton, requiring an immediate confidence-building
rendevous before his assets shrivel and die."       -hehe... That win the chick vote?
