Hello, I installed the delta glider iv in orbiter 2010. it works fine but when I try to enter and land on the surface of the earth ship explodes because it heats up the helmet. :hotcool: How I can land without exploding?
thanks
thanks

Could you try to describe this better? Are you saying you are trying to re-enter the Earth's atmosphere and trying to land? What do you mean by 'heating up the helmet'? do you mean the ship?

Even though I'm technically stupid I will make reference to the autopilot and the dgiv manual. If you aching for manual reentry I will recomend you choose a trajecptry that scrapes the upper atmosphere and use the aerobrake put the nose up because you are looking for lift not drag. Make sure the temp dosnt get high or you are screwed.
I think he means during reentry, it overheats and explodes. The easiest way is to go to "parameters" and uncheck "damage and failure simulation" on the launchpad. Or you can open the DG4 Config application it comes with, and turn on "chicken mode"
After you get more familiar with flying / reentry, you can turn the damage back on and try to perfect your technique without exploding in the process

Your entry angle is probably too steep (you should keep it limited to 1.5 degrees). Like people said, start practicing with crash disabled - you'll soon get good enough. Good luck!

No, you're looking for drag, not much lift. And the DGIV produces almost no lift at beyond 30° AOA...
Yup - winged vessels tend to disintegrate if you thrash them into the atmosphere without a care in the world. Capsules can be a little more forgiving (in my experience). There's a bunch of Orbiter tutorials out there for landing, including some on youtube.
Check them out, and don't be put off that it takes a while to get it right. It took me 9 consecutive tries to successfully land the shuttle from orbit - and that was with experience of landing DGs, XRs, capsules of all sorts...but I eventually got it right and I haven't majorly screwed up since (to the point where the craft didn't make it to the runway)
In a nutshell though, basically you're wanting to get rid of all that kinetic energy you've got by using the dense atmosphere as a brake. The problem with this is that doing so generates huge amounts of heat on your craft - so it's kind of a balance between getting the optimal deceleration and minimal heat. This is usually accomplished by managing the craft's angle of attack (AoA) - essentially the angle between your wing and the oncoming airflow. So, once you've learned to control your AoA, you'll have a much easier and less firebally time. However, re-entering in a winged craft which produces lift does have some extra complications:
As you hit the denser atmosphere at these incredible speeds, this wing will naturally produce lift. A lot of it. Unchecked, it can threaten to bounce you back into space, like a rock skipping across the surface of a pond. So - the answer is to redirect that lift by rolling to one side, and directing the lift to the side instead of upwards. Obviously, this will change your predicted flightpath several hundred miles away from your landing site, so then reverse that roll so you're facing the other way to correct it. Takes a little bit of practice to get it right, but having an MFD like Aerobrake comes in incredibly handy - as does GPCMFD's OPS 3 function.

Reentry isn't exactly the easiest thing in the world. When you go into the air from orbit, it can get very dangerous at those speeds, because the ship can become very hot. Don't worry, this is normal. A spaceship usually has a heatshield. If you look on the bottom of the DGIV, you'll see a black surface. That surface can get really hot, and still stay safe. However, for this you have to keep the heatshield "in front". Otherwise, the heat reaches any other part of the ship, and that is not good.
Sure, even doing everything right won't save you if you come in too fast, or too steep...
Anyway, did you know that the DGIV has a reentry autopilot? To activate it, all you need to do is press the following keys:
This will activate program 105 (the reentry autopilot) and keep an angle of attack (how high your nose is pointing relative to the direction you're going towards) of 40. The Enter key just tells the computer to use that program. The E starts the autopilot.
Note that in this situation, the numbers mustn't be on the keypad, use the ones above the letter keys (forgot how they're called).
Hope this helps!

The DGIV has TWO re-entry autopilots. One is "manual" (P104 IIRC), and maintains a set AoA (which can be adjusted during the re-entry - see the manual). The other is a "fully automatic" autopilot, which alters the AoA as needed to maintain a Vertical Speed of -80 m/s. There is a scenario included (with instructions in the description) that demonstrates this AP.
The DGIV Manual is your friend, and contains lots of useful information on how to re-enter in the DGIV. Essentially, you de-orbit by burning prograde until the Flight Computer shows a 1.2 degree Re-entry Angle (D3, as I recall, to set the computer to de-orbit mode.) Then you change the Flight Computer to show hull temps (see the manual for instructions). Basically, on Earth, you want to keep the descent rate at about 80 m/s. Start with an AoA of 40 degrees, and INCREASE the AoA to increase the descent rate, DECREASE the AoA to decrease the descent rate.
I'll add that the descent rate is the same as a negative VS (as shown on SurfaceMFD), except a negative VS is a positive descent rate.
This tutorial will help you understand what's happening during a re-entry:

Hiya Tecinpro, 
to the forums.
Don't forget, if all else fails, eject! (Press Esc 3 times). At least then you can blow things up without feeling guilty about your crew... :lol:

Toast! :D
Maybe it's just me, but ejecting while moving at high speeds through thick atmosphere with extreme heat building up around the ship seems like a bad idea.Hiya Tecinpro,

I don't think you can eject at high altitudes.

You can eject in space. I think its possible.

It is.
Trying to wrangle in five astronauts and a deployed emergency shelter module . . . that's more borderline impossible.

I know its possible, it was just a figure of speech.
And about that last part, without the emergency module, that's more impossible.

Yeah, and if you're already in the middle of reentry and eject from the ship, you're gonna burn up anyway. Might as well hang out in the ship and prolong your life a few more minutes, maybe try to save the craft and the rest of your crew...
