[OrbitHangar]

Author: virii2k

*Various bug fixes.
*2 Launch sites.
*Max Q.
*Ability to launch 2 Delta IV vehicles each with their own autopilot.
*9 Pre configured payloads with the option to save up to 3 custom
payload configurations with visual payload alignment.
*Updated autopilot for altitudes up to 1000Km.
*Added pdf documentation.

Excellent, I have been long awaiting this!

Can't wait to launch my Extended Mars Package.

Thank heavens, a productive upload to OHM.

Thanks, a lot mate!

Thanks for the comments. Let me know if you find any bugs.

If you get the right launch angle, the view from the ground looks like the Corinthian Star Cruiser from StarWars leaving..! Khool!

 

[mojoey]

it looks awesome! Can't wait to test it out

A beautiful mod. One of my favorite launch vehicles.

However, I think that there is an error with the autopilot in that it is holding the heading for too long.

The heading is correct for the desired inclination at the launch point. However, as the rocket heads downrange, it is natural that it's heading will be changing as it maintains it's orbital plane. If you try to fix your heading as constant through the launch, then you end up making a small plane change that gets worse and worse as the launch proceeds. Essentially, during launch, you are making a plane change into the wrong plane. That is why you need to make an unnecessary course correction to get back into the right plane.

Try to hold the heading for only a short time. Then, hold the lateral attitude constant in the prograde direction (i.e. only use pitch, and not yaw, after you get into the orbital plane). I bet that will make the launches more accurate, and eliminate the need for a course correction.

Thanks for the update,I have been looking foward to this for sometime now.

The scenario loads, but I get CTD on lift off and when I use the "M" config key. This happens in all scenarios.

I have Win7 64bit
Athlon 64 X2
4Gb ram
ATI Radeon HD 3800

 

[virii2k]

Can you try it on a clean instal of orbiter?
I just tried on 64bit windows 7 and didn't have any trouble.

:speakcool: Nicely done!

Thanks! Can't wait to give these a try.

Did a couple of launches with the new version and it's great! especially the 'save custom payload configurations' and the 'visual payload alignment' features :thumbup:

Everything is great,love all the new effects,and features, especialy the H2vent at the launch pads,but I am having alot of problems with the autopilot,for some reason the rockets want too keep spinning,and once in awhile I'll make it to a stable orbit.Anyway thanks for all your hard work.:thumbup:

 

[virii2k]

Make sure you shutdown any unnecessary programs running in the background. The autopilot is very cpu intensive, atleast on my machine.
amd xp 3000+ single core
2gb ram
512mb video ram.
If I do anything else while autopilot is active, like open a web browser or something, the autopilot will lose control.

Sorry guys.

There's something missing here. Hit the M key and instant CTD. Hit A and launch, then very smart fireworks, but then CTD at the moment of lift off. I'm thinking there is something in the modules not working right. Perhaps dll files compiled in something I am not running.

Hi virii2k, yeah I do having everything off in the background.Thanks

Try installing it to a clean installation of Orbiter.
Before uploading it, I installed it to a new install of Orbiter and
tested it on a XP machine and a Windows 7 64bit machine.

It was compiled with Visual C++ 6.0

 

[leo9man]

Well a Clean install did the trick.

Probably about time I had a good clear-out anyway.

Wonderful add on. Thanks

Excellent addon! :thumbup:

I think I found a bug. When I load the Delta IV 5.2, if I press the "M" key, I get CTD. It only happens with the 5.2. The other models work fine. It happens on a clean Orbiter install too.

If I load another Delta IV (the Heavy, for example) and use the "M" key to change it to the 5.2 with the payload of my choice, it works fine. But if I press the "M" key again after the 5.2 is loaded in the scenario, I also get CTD.
