Project CST-100

[N_Molson]

Great news.

Is the download on post #298 the "latest and greatest"? If so, I'll try to take it for a spin this weekend and flesh out the documentation into something suitable.

It is, but I think you will have several new versions before next weekend

Groovy. The doc needs some work, mostly screenshots, list of dependencies, etc.

Can you guys who worked on the project PM me with what you did (generally) so I can credit the work? The list seems to have grown... Kudo's to Dr. Martin first or course for this fine (and free) simulator.

I already have a credits list ready, I'll send it to you.

then at 1st stage separation, the 1st stage rockets ahead of the second stage.

I reproduced that one. That happened to me using x10 time acceleration during separation. Not a big problem ; it causes the first stage engine to burn a part second too long ; hence it "rams" the second stage.

I will fix this by introducing a fixed delay between MECO and separation. It exist in real life anyway. I'll have to watch closely a couple of Atlas V launch replays.

Ok, Im working on the Capsule, Service Module, and Nosecap meshes , I can send them to you within the next hour or two. They might be a bit off size because I thought you had said it had a 4.54m diameter instead of 4.56m. I should have checked while I was working on resizing them.

Here are the meshes: http://www.mediafire.com/?uv7oijsvzzirx9b

Just ran the mesh through Orbiter in the original SC3 file, it seems all the meshes need to be rotated.

 

[N_Molson]

The mesh needs to be rotated.

But we have a, huh, small little scaling problem I think :lol:



Boeing is testing a new space transportation concept :



Take your time, I can work on the rocket with DemoCap for now.

Uhhh, I didn't do that It was the right size in Sketchup, dunno what happened there.

Scale in Anim8or:

Thanks Liber, got them scaled correctly, I'll send them to Molson and continue working on a VC.

It's SketchUp export problem.
You can have right size in SketchUp but after export or import dimension are incorrect.

 

[N_Molson]

Ah, it looks more reasonable like that :thumbup:

Here are the current meshes: http://www.mediafire.com/?0l4pypnr1r3v95g

Atlas-412 alpha v0.23

Here's the latest one.

New features :

- The guidance program now handles pitch, yaw and roll for both stages. So it should be functionnal.
- You can set the launch heading through the scenario file. Look for the "AZIMUTH xyz" parameter in the "launchpad" and "stage2" vessels. More details in the now included readme file (Docs folder). Thank you to test heavily that feature.
- Focus switches to stage 1 when the rocket lifts off.
- The rocket PMI and cross sections have been adjusted to be much more realistic (first stage only).

Much better, but there is still a rotation to do.

Its right side up when not attached, but on its side when it is :hmm:

 

[liber]

Orbiter\Orbitersdk\utils Shipedit.exe and rotate x for 90° or -90° and save.

That's because you haven't defined the Touchdownpoints as a tail-sitter. With planes, the +Z axis (forward) is horizontal. With rockets or capsules, it is vertical. Check by activating "Visual helpers -> Coordinates axes" in Orbiter (works only with D3D7).

Of course, but it's better if ky does it directly.

Launch AP is working well, did multiple tests, launched with headings of 50, 60, 70, 80, and 90.
