So I got some progress on the IVA. Right now I am currently in the process of making the UV map. Texturing will probably start later this week. I also got some little progress with the cargo dragon.

The top of the Cargo dragon is 1.25m to 1.875m then the bottom is 2.5m.

And enough to use it as a LES, so it does need to have some oomph.

Doesn't it already have enough thrust to be used as an LES?

(replied about manned IXV)I second this

Not sure what the manned IXV would look like. If you guys have any reference pics please post them! :)

NO NO NO come on dragon pod you can do it ;.;

Lol, if it doesn't make it first, it will come after the IVA most likely. :)

I'm not sure. I'll test it.

Also, keep in mind on the IVA, the pod schematic (for the Cargo Dragon, but they're probably fairly similar) looks like this: dragon-spacecraft-line-drawing.png

Which brings me to a question: What actually goes in the Trunk? Is it supposed to be just for payloads, or is it supposed to house life support? Because it seems fairly empty. The schematic for the (also Cargo Dragon, again, but it's all SpaceX has on their website!) trunk-drawing.png Should some of that room on the V2 be used for life support, or is the pod entirely self-containing? If so... what's the trunk really for anyway? It can't just be electrics.

SNIP.

One time showed some computer stuff in there but on the wiki

First launch of Dragon using trunk section to carry cargo.[89] Launch was successful, but anomalies occurred with the spacecraft's thrusters shortly after liftoff. Thruster function was later restored and orbit corrections were made,[96] but the spacecraft's rendezvous with the ISS was delayed from its planned date of 2 March until 3 March, when it was successfully berthed with the Harmony module.[98][99] Dragon splashed down safely in the Pacific Ocean on 26 March.[100]

EDIT- I use it for LS going to see if can make it to EVE or Duna flyby :)

Thanks for the pic, though from looking at the webcast and pics over and over I think the bottom is pretty flat from the looks of it. BTW, I think it's a bit too late to change the IVA since I already started texturing. But I could if people really want, take another look at the model.

I read some stuff on the cargo dragon when designing it and the capsule is for pressurized cargo and the trunk is for unpressurized cargo.

EDIT: Scratch that, I think I'll change the model a bit tomorrow.

Some progress on the IVA. I think the new mesh is pretty good and I will start unwrapping the UV map tomorrow. I won't have time to do it tonight. Tomorrow I will also need to figure out the exact scale of the IVA. Actually, I might be able to do that tonight on my phone.

What if you did a Mars Colonial Transporter?

:P

I'll think about it once I get everything on that poll done first. :P

I don't know how it is actually done on the real Dragon spacecraft, but common sense might help answer this question:

- Firstly, breaks or continuities in the heat shield surface such as hatches* should be avoided, as they form an additional point of failure that could compromise the integrity of the heat shield. So that means no bulk life support items can be transferred, meaning that the pod itself must transport all the food bags the crew will need for the entire journey.

(*Aside: The hypothetical USAF Manned Orbiting Laboratory version of Gemini had a hatch built into the heat shield, but this was because the Gemini was going to be stacked on top of a lab module, and at the time docking techniques were still in their infancy)

- Life support gases and fluids, cooling water and power/data connections are made using an external umbilical interface that goes from the trunk, around the heat shield and onto the side of the crew pod (The umbilical will need to pop away before the trunk can be jettisoned prior to re-entry.) So in this case, the pod holds some of life support gases/fluids as an emergency reserve, while the rest can be piped from the trunk.

The VA pod, which was flight-tested several times, also had a hatch in its heatshield. The MOL version of the Gemini also made a single test flight.

Isn't that hatch on the side? While within at the exposed portion of the spacecraft, it's not right at the point of maximal heating, right?

Yeah that's the hatch on the side. I'm a bit confused of what you are asking.

Apologies for the confusion - basically, I was meant to say:

- The Dragon's trunk could not possibly be used to carry food because that would require an EVA to retrieve the food bags. Food should be stored in the pressurized crew area for easy access in emergency situations

- The trunk *could* carrying additional water / oxygen tanks, but you would need an external umbilical on the side of the Dragon pod.

- The reason I mentioned heat shields with hatches is because I wanted to point out how impractical it is to cut a hole in the heat shield just to transfer extra food from the trunk to the pod. I know of the VA and the MOL versions of Gemini having flown experimentally, but presumably there's a good reason that wasn't the norm.

There's a good reason that thte VA never flew crewed - the Soviet Union kinda collapsed. But you're completely right, it makes no practical sense to store food and water in the trunk of the Dragon.

Woohoo !!! you got it :)

Yep, all that's left I think is just reposition it so there isn't any clipping.

EDIT: Done.

- - - Updated - - -

New version is available on KerbalStuff.

-Rodan IVA added.

-New folder layout

-Buffed thrust up to 150

Wow! This is a fantastic looking pod. If you weren't already aware though, you've got some internal polygons (from the draco engines) which is slowing down the game a little. Also, due to how subtle the window recess is, is it worth using a bumpmap to model this rather than more vertices? I don't know if it would look worse or not, and I don't really know how much of a performance improvement it would lead to. Sorry if I came across negative, I really love the design of the capsule!

Great stuff eh! :)

What was the problem in the end? I'm curious.

Wait, you are seeing the engines from the inside? I thought I fixed that. Could you share a screenshot or something? I'm not too keen on having a bumpmap since I'm not the best at making them. It didn't come negative, atleast to me, thanks for the compliments about the pod though!

Well, pretty simple actually. The props, were not a child of the model and I had the model attached to a gameobject with the prop generator thing but that needed to be attached on the model itself. :P

O Man Kerbal Dance going on now and great job on the IVA for Dragon 2 launch it last night just pod and truck forgot to put on RCS whoops but still landed on the VAB with just the thrusters hehe was good just alittle bad landing on my part. :)

Nice! Don't worry about putting on RCS for the cargo rodan since it will have built in RCS.

BTW what type of texture style would you guys want for the cargo rodan? This or This?
