I've found what i think is a bug on DGIII mod alpha, in the Life support system.

If you want to set a 8°C  temp in cockipt using the auto mode setting with the temperature button, turn on L, when  it pass
below 10°C, it fall to 0°C in one step.

Strogoff aka I want to freeze in my DGIII :stupid:

There's another annoying bug. I can't set a temperature below 0°C...

I want to freeze in my DGIII !!!! :stupid:

WHY THE HECK WANT YOU FREEZE YOUR DGIII??????????????

Well, if you want to know, for two thing.

First aval, I just want to try a cool  freeze style hyperbolic orbit near the sun (but really really near... :hot: ) :doubt:
It's a old dream to be in the sun in a fridge. :drunk:

Secondly, If I want to plan a travel to Alpha Centaury,...  I need a cryogenic system inboard. :zzz:

I hope you understand now the importance of those bugs :bug:

LOL!!!!

How long will a trip to Alpha Centaury take? In a DG???? :)

Speaking of temp, does the DGIII heat up near the sun, or only during atmospheric reentry?
That'd be cool if the temp alarms started going off when you get near the orbit of Mercury :)

The base ***space temperature*** is computed effectively from the distance to sun

It seem to me that the alarm *may* sound if you go too close.. try perhaps from mercury
and head to the sun. (never tried from closer but near venus you get a more hot ***space temperature*** )

Bah, I just loaded up a scenario landed on the sun and got 0 degrees C.

[sarcasm]How realistic is that, dan?[/sarcasm]

To tell the truth, I think very realistic, at least instrument wise. I remember that for some reason, (perhaps the lack of
molecules moving rapidly?) A instrument measuring temperature near the sun would get something like that, it's like a
cold heat, but it'll still fry you many times over in real life.

more interestingly, I got about 27 G's while landed. that sucker was too heavy

Hm. Sun is not solid like the planets in orbiter? Didn't know that one..

Hey Freespace, a while ago, there was a discussion on the main forum of how fast can you get slingshotting around
the sun. Now, crashing into it is one thing and you did that. How about you try to sling around it. And when you are
near periapsis burn rubber. The burn should be VERY effective. I saw people talking about numbers in the realm of 50
or 100 km/s (that's 50.000M in orbiter MFD). you should try that, having that 10AU scenario already.

Cheers,

Actually a plain slingshot around the sun will gain you no additional velocity, as orbiter considers the sun to be a
stationary body. performing a burn will, of course, give you additional velocity but a plain vanilla pass of the body is
uneffective.
The velocity gained by a slingshot is proportional to the orbital velocity of the body, and the maximum delta v is
equivalent to the velocity of the body. This means that you'll never get a slingshot which gives you more than
29.6km/s dv from the earth.

Ah, true, but remember that you do get a speed increase while you're closest to the sun. I just want to play, don't
throw laws of physics on me! :)

Hehe, kind of reminds me of the famous "Never tell me the odds" bit :)

Hm.. that is without an additional burn right? This I didn't know. I always assumed you get no extra deltaV unless
you thurst at periapsis and if you do it is highly efficient.... so I'd assume then you get the the best deltaV if you
approach the planet along a head on vector -> umm...meaning you come in from the opposite direction in which it is
traveling? So when you slingshot around it, you get your original velocity back (that would be according to Kepler),
plus the planets orbital velocity.. right?

How much would you estimate you can get if you skim the sun's surface (wearing a REALLY strong sun screen,
naturally) and put your hit full thrust as long as its effective? Mark V. engines AND Turbo pump... bear with me, I
wanna give Freespace a velocity figure, he can't beat, so he'll be frustrated for the rest of the summer holidays :)
Let's say to make it more fun, that you burn ALL of dg3's fuel, so you start burning way out, carry on while going
around the sun and burn on your way out too, burn split in half around the periapsis to give it maximum effect.

I'll just have to improvise. maybe if I get a speed boost from jupiter beforehand, aim so that I get super close to the
sun, and then use use all my fuel when I'm at the sun then. with the least realistic fuel settings of course. ah, but
that kinda course plotting is beyond me probably... not to mention the time It'll take just to do that. I hope the next
orbiter version has a faster time compression. :) hell, maybe I'll try for a resonance orbit of jupiter, but I know that's
way beyond me.. :)
