Here's a mesh I'm working on to go with the FDM. Still needs work though, and might need some idea of how to go about doing the landing gear.

How is the progress on this? I found that you can not fly above 65,000 feet but you can start the flight higher and come down. Will make for a nice rentry and landing sim for it with the height and location info for reentry.

Hmmm... :? I'm just doing the 3D mesh modeling, but the guy doing the flight model part of it might have answers if he stops by.

You might want to check here to give you a start on the mesh:

http://www.hal-pc.org/~jsb/shuttlepov.html

This is a NASA model from some years ago.

There is a JSBSim shuttle model which I began working on some years ago. It hasn't been touched in a while. I could probably improve that a bit, which would be a good start. There's no reason why it shouldn't work up to a very high altitude, as well, since the JSBSim atmosphere model should be able to handle higher altitudes. A big challenge for the shuttle model would be the scheduled profiles of the body flap and split rudder, and the rest of the flight control system. Also, the real aero data for the shuttle is in two volumes with a total thickness of about 10 inches! :-)

After doing my high altitude drops I became interested in low space in FG. I suspect that it is a whole section that would have to be written to model some space in FG but a space station and shuttle would be nice.

Are those data even available? :lol:

Here is a quick Nasa search, I'm too tired to read and narrow it down right now but you could spend all day at the NASA site reading technical info,

On a related note, how high can you fly in FlightGear? I took the X15 rocket up and maxed out at 65,000 feet. On the other hand I have taken the Harrier and used the thrusters to control a drop and started at 500,000 feet and did the same with the X15.

I have not tried this, but I was under the impression that it was the pressure altimeter that fell out at 65,000 feet and that an appropriate aircraft could climb higher. Since our coordinate system contains the entire planet I think that one might be able to enter orbit. I do suspect that the tile cache would freak out before that, though ;)

Cheers,

Will have to try again but I was having trouble with the X15. Seems it runs out of fuel maybe.

Yeah, if you make the visibility high enough so that you can actually see the earth it has some issues. I wonder if it's possible to use lower-resolution textures at high altitudes and somehow "merge" the tiles together. A question for the developers I guess.

Finally got around to UV-mapping the thing. I think it'll look neat with a proper paint job. Here's the current template for the exterior, in case anyone want's to start doing livery related stuff.

Should be uploading the mesh to ShareCG as a .obj soon. Just gotta put the ReadMe files and all that jazz together.

-----Edit-----
I didn't waste too much time in writing up the readme.txt and uploading. So now the base .obj mesh should be available for further work. Downloadable here: http://www.sharecg.com/v/28809/3d-model/pauljs75_NasaShuttle

Great! I was working on a shuttle some time ago as you might know. I do have textures which we could use...

I just started some work on texturing it also. There's a new post in the texturing thread in regards to that aspect of the model.

Now I'm curious as to how long it'll be until someone picks it up from where I left off. :mrgreen: There's still a lot of work to be done.
