Hi! I've just decide to start my own add-on development project. Even with zero experience in meshing and making textures (although I DO have C/C++ coding experience), I've decided to make my first project a large one: offering all 8 major versions of the Long March family of rockets available today and all 3 Chinese space launch sites to the Orbiter simulator. I have decided that the full version of the add-on will be coded with C++ directly (although I would not rule out an interim version based on the multistage module), offering a complete autopilot and animations on all rockets and all 5 currently active pads (e.g. swinging umbilical arms and engine nozzles that can gimbal). Right now I'm still inside the data searching phase (turns out that it's really difficult to nail down basic parameters for the Chinese rockets, although the situation's slightly better than the Falcon 9/Heavy :P), but I think I will be able to make some visible progress here in the next month or two. Don't expect me to complete it soon though: it's a rather big project, and I think the most optimistic schedule I can give is releasing in Q3 2012 (in SpaceX's timescale :P).

The reason I've decided to make this my first project is because of the very high launch rate of the Long March family of rockets expected in the next few years: averaging at more than 20 launches per year (in fact it could be even higher: China launched 20 times in a 7 month period between June 2011 and January 2012!). Between 2000 and 2009, the Long March family is the third-most used rocket family in the world (behind the R-7/Soyuz and Proton families), and it is currently leading the scoreboard for 2010-present. So it seems necessary to offer the rockets to Orbiter to complete the picture of spaceflight in the 21st century. It also serves as an opportunity to advertise on Chinese spaceflight (on both the bright and the dark sides of it's development and difficulties faced), as not too many information has reached the "Western world" from Chinese sources.

Stay tuned for news on the development of this add-on, as well as probable follow-up projects (including Chinese satellites and retired Chinese rockets) here. Comments on this add-on are welcome. :cheers:

Sorry for the lack of updates, but meshing turned out to be a headache to me, and I am still trying make a prototype rocket mesh. :uhh:

Here's two problems that needs your assistance:

1. I'm currently using anim8or to make the rocket stage meshes. Since I'm making real-life rockets and spaceports, I would like to know how long 1 meter in the Orbiter environment is in anim8or? What's the conversion factor?

2. How can I make vertical stringers on parts of the outside surface of a rocket body? I'm thinking of something like the stringers on the Shuttle External Tank.

Any comments would be appreciated.

1. Here we're lucky : units in Anim8tor are meters. So no conversion needed :)

2. I did something like that with the DG-Launchers, simply using the "cube" primitive, grouping, converting to mesh and using the mirror function liberally. The idea is that each stringer is an "elongated cube" placed on the tank hull (since you know the diameter of the tank, it is easy to find the location).

And we're counting on you, as China is clearly becoming a major actor in spaceflight ! :cheers:

Sorry for the lack of updates, but after a quite turbulent period and problems with learning how to make rockets (I even have considered abandoning the program), I have decided to re-start it, albeit at a slower pace and down-scaled (and hopefully with support from other add-on developers; PM me if you want to join in!).

You can see my first product here: http://www.orbiter-forum.com/showthread.php?p=379069&postcount=4722. Hopefully I can make another update soon....
 
Development of the rocket meshes have seen quite a bit of progress, and it's looking good (although it's sort of "standing on the shoulder of giants", as I have used modified meshes of rockets from other add-ons) right now. I still need to make modifications for the meshes (probably needs some new mesh development) and learn how to apply textures before I can say that the project has entered the alpha stage, however I am pleased to report that the rockets are looking good. :)

Long March 2C





Long March 3A





Long March 3B





Long March 3C





Long March 2F for the launch of Tiangong 1





I plan to get a first test version of the Long March 2D, 4B and 4C by tomorrow. Hope that I can put an update by tomorrow. :tiphat:

Up-coming: textures for the rockets, then base textures (2D/3D) for the three main Chinese launch sites.
 
Well the necroposting warning reminds me of how long I have been unable to work on this project...... :uhh:

Yet there are still some preliminary work that I have done. The MS2 guidances is now starting to look like a normal launch, and the meshes have been slightly improved. With a little bit of spare time right now, I may try to put on all the textures on the rocket stages.

Next up: the launch bases. With the new Shenzhou/Tiangong add-ons now out, the Jiuquan base would be the first to be re-made, given that some of the buildings are already available and the terrain is flat (so I can just slap the ground textures onto it and done with the terrain). Then there's Xichang (where Chang'e 3 will leave for the Moon later this year), which would need some serious time to finish it......

Don't expect anything to be out before the next summer ends though...... :shifty:
 
More suggestions

More than three years since your last updates. Is this project dead? I haven't really heard much about it for a while. There are so few addons from and covering East Asia. The Middle Kingdom count on you. Hope you continue this great work.

I read somewhere that one can grap the mesh directly from Google Earth. You could save a lot of time. There is a nice service tower at the Jiuquan Space center, but the resolution is average. There are also other structures around.

Now you will have to add the CZ-9 moon rocket to your list, and maybe the Kuaizhou, CZ-6 and CZ-7. Of course those rockets need payloads, such as the Tiangong-2 spacelab, the Tianzhou cargo spacecraft, maybe some Yaogan triplets, some Tianlian data tracking sats, and why not the entire Beidou1/2 array of GPS!

Since you started this lonely endeavour, new spacecrafts have been launched and thus might be worthy to model such as the DF-41 tipped WU-14 Hypersonic Glider, or the Moon rover Yutu and XiaoFei the mini-Shenzhou lunar return test vehicle.

Last but not least, do not forget the promising past. The Shuguang-1 civilan spacecraft along the military Qianjunbang-1 surveillance spacecraft and Qianjunbang-2 space fighter.

:tiphat:
 
It's still in a hibernated state right now until I know how to make better meshes, texturing and coding (I decided that when this one is eventually developed it will be directly using Orbiter's API). Due to the large scale of this project I think it will be released in several packs once it is pushed out.

Unfortunately I still need some time to flesh my skills before even re-starting this project, so I can only say that any products will be released on a Tuesday in some months time....but I promise to re-start development ASAP. :tiphat:

The 1st phase will probably include the existing 3 launch bases, all Long March rockets in service and maybe some "generic" Chinese satellites like their comsats, navigation satellites and Earth observation ones, with Chang'e 1/2 as the "flagship spacecraft" of that phase. Even completing this part will already be a huge task for me so don't expect it to be completed soon. :shrug:
