It would be cool to add a "download new DGIII scenario" sticky thread,
a bit the same than the skin thread.

Most people don't know how to set new scenario and a lot of
intteresting scenario can be added as somes of you already know:

- scenario with a failure set (must reenter/land without main thrust)
- scenario with power failure (all off, in error and text state that user must use the emergency power)
- more window launch
- more "rescue" scenario ?
- more cool place to visit (asteroid etc etc)

This thread can be sticky here and the link will be given in the DGIII download
page.
If we set this up it would be cool that you send me the scenario with a litle
title and description and a 250x??? jpg image so it's more attracting, the post can
look like this below : (fake image)

LOST IN SPACE  author: Janez mission: easy



Description:
You are lost with all system off near phobos you must blabla blab bla bla (long text possible)

Download this scenario here (80Ko)



what you think ?

Sounds like fun. But I won't engage in it for the time being. I''m a little tied down right now.. :)

Oo! Oo! I've got a few :)
Do you want me to post the scn data in the thread or link to a downloadable file elsewhere?

Send them to me by mail, I'll post them


If would be REALLY cool if you include:
1- a title
2- a text description (you know my *level* of english)
3- the level of the scenario (hard, easy, medium)
4- a jpg image 250 pixel width
5- the author's name (because somes preffer their nickname some preffer their real name)

All those info that will goes on a download page or on a thread in the forum.
(will do it as soon as I have 4-5 of them)

And if the Scenario archive (zip) is already packed ready to
be unziped in the Orbiter directory it would be really perfect. :beer:

If you have many scenario you can group them by theme
(ie: "rescues missions"  by AphelionHellion )

If the scenario use a third party vessel or add-on, please provide a link
to this vessel or add-on, so they are "zero-headeach-scenary"

That could be neat,

Dan

Sounds Great~!

I'll try creating a few fun ones that involve precise timing, cross-station acrobatics, and sexy results. :)
Testing User Created Scenarios (or UCSes, as officially named) would definitely be Fun !

Hehe, good idea, I actually proposed we include some of these scenario in the orbiter distribution and manual :) I
marked it on the index site.

I'm kind of low-energy at the moment, but I will try to polish up that ascent scenario, so I can pack it up and put it
online again. I see people visiting the page quite often, but can't download it :(

Dan

I think the link is missing :bug:
;)

But it's a cool idea. I've just install'd the DGIII again, and will try to set up some scenarios as soon as my vacation
starts.

I tried the Rescue mission on IO (hard).scn but I didn't find it that hard :pfff:
I set the DG on MAXfuel, but when I reached Io I decided to tow the stranded DG with the DG-Rescue back to Europa.
After delivering the poor thing at the Europa-OB1 station, I still had over 80% fuel left.

Am I doing something wrong, or what is the ISP in the max setting?

Hehe, the one who is going to be writting a reentry tutorial for the manual might make an spin-off adventure scenario
with a few additional problems. Maybe a ripped off antenna, to reduce max temp, so you have to make a very flat
and long-winded reentry. Start skimming the atmosphere over Australia and land at KSC or something. Or at the top
of the VAB building to make it exciting... hm. this just gave me an idea.

:)

If you put a landing gear failure in a scenario, will it lower max temp for reentry (ie act as if the wheel wells are open)
or not?
I just wanted to have a scenario where you can't lower your landing gear. I've found it's possible to land vertically using
hover engines (without sustaining damage) with the gear up as long as your final touchdown speed is very, very low.

If they are failed in raised state I don't think it will cause any problems....

Hi here.
Pleace, check description for errors (i know, my english is horrible :) )

Antarctica touch down
Author: Alexander 'Shirson' Nevskiy
Difficult: Hard




The DG-III "Iguana" crash landed on antarctic ice. We do not have accurate information regarding crew
status nor the exact shipwreck coordinates.
Probable location of the crash site is estimated to be between 64°W 70°S and 66°W 72°S.
Unfortunatelly, only one rescue glider designated "Extractor" is equipped with the right search systems to detect the hull of the wrecked ship and time is critical in this matter. Do not waste time with atmospheric flight - rescue the crew as soon as possible, otherwise they will freeze to death, when the "Iguana's" on board life support system fails completely.

Your objectives:

1. Take off from CC (Cape Canaveral).
2. Reach the crash site.
3. Use onboard LRA (long range antena) to locate the wrecked "Iguana".
4. Land near "Iguana"; find and pickup survivors of the accident. (DO NOT try to refuel from the "Iguana", the glider is severely damaged )
5. Start immediately and convey the survivors to any starport for medical assistance.
6. Leave the crew of "Iguana" at the starport and refuel the "Extractor".
7. Return to CC.

Good luck.

-----

You must complete the above objectives within 180 minutes (or less).
DO NOT swith control to other ship (if you a real pilot, of cource ). Switch to crew of "Iguana" only to transfer them to the "Extractor".

Yaeh, but with Fuel Reserve = "Big", mission have difficult "almost impossible" :)
I have 1 succeed out of ~40 attmepts.
(With Fuel Reserve = "Huge" or exact coordinates - no probem)

Hm.. Seems to me that should not be such a problem if you approach it methodically. In theory you are making
a "ballistic" flight from CC to South Pole (more or less), which means you take off and head for a polar orbit (close to
180deg heading) and then cut your engines to take you on a "cannon ball" drop to the target site. BaseSyncMFD (or the new Arrive MFD on orbithangar) should help a lot in this.

The problem of course is to judge the right reentry timing so that you don't overshoot and the other problem
obviously is that if you go ballistically you will have a pretty steep angle of reentry, hence high temperatures. You are
not at orbital velocity, but you are probably going fast enough to induce quite a lot of drag at a reentry angles, say..  
20 degrees or so? You could possibly improve the situation by applying hover engines once you start dropping, keep
your pitch angle perpendicular to your flight path, maxing the effect of the hover engine braking.

I'll have to try it. I haven't really started up Orbiter in a few weeks now :)

Simon any input on this from the math/physics point of view?

Cheers,

After dozen attepmts to fly close to 180deg heading, i stop it. 180° - wrong way :)

"The problem of course is to judge the right reentry timing so that you don't overshoot and the other problem

Yeeees :) Ship have not at orbital velocity, but enough to burn in atmosphere. For direct ballistic trajectory (180°)
velocity =~7 km/s and reentry angle more then 4-5°. "Extractor" stability burn in atmosphere.
Using hover engines for dec velocity mean no fuel to evacuate people from crash site.

I'm use other way. Starts from CC and heading 0°. On north pole turn plane to 115° (crash zone 64°-66°,
center=65°. 180-65=115°).
Activate IMFD and enter coordinates for center of crash zone (-65, -71). Wait for radius-vector of ship placed opposite
target. Retrograde and down Per for 70 km.
After reentry, make atmospheric landing and use LRA for locate "Iguana". Calculate new coordinates (using internal
DGIII calculator :) ), enter new ccodinates into IMFD and make final aproach with low altitude ballistic "jump".

Neat idea , tell me when you scenario is really completed included the correct "how to"
and your scenario will be the first one of the new "DGIII scenary post" ;)

Karramba! I havent stable "how to" for this scenario, with "Fuel reserve = Big" :(
I will look DocHoliday's solution :)

Sounds good :)

(I have ideas for more scenarios. Work in progress:
-= "Delicate" cargo. =-
Module with dangerous contents falling into Earth atmosphere from high orbit.
Crew of "Extractor" must intercept module and stabilize orbit, before module reentry and burn in atmosphere.)

Maybe I can help you with the translation. It's no problem as long as I know, what you wanted to say. But I believe
some other people who are non-native speakers might find it too difficult to understand so I'm gonna post a quick
clean up of your instructions if you don't mind.

Cheers,

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.
