Commercial Crew Spacecraft Competition

[Prober]

Thought it was time for a Commercial Crew Spacecraft Competition thread.

This might be premature since we don’t have all the details; we can add those in the future.  The Idea is to see all the spacecraft side by side for a comparison.

I’ll start this out with one of my favorites, the CCM.

These two pics of Orion and the Composite Crew Module (CCM) really impressed me.   

From the fine article:  http://www.nasaspaceflight.com/2012/07/nasa-esd-key-orion-requirement-lunar-missions/

Having seen the Apollo, the space inside is impressive.   I realize they are standing in the crew supply area in the 2nd photo; but even with equipment installed, the CCM/Orion space is impressive.

I’m not going to post pics of the others; I leave it to the supporters of each in the competition to post their own.   Enjoy all ..

Did you mean competition or comparison?

Anyway, I took the liberty (heh) of adding in Dragon and CST-100 into the image you attached.
 - The Dragon illustration is not from SpaceX, it was created by the started of this thread: http://forum.nasaspaceflight.com/index.php?topic=29182.0
 - The CST-100 image was 'shopped to remove the SM, but I was too lazy to remove the "claw'. 

These four capsules should be to scale.

EDIT: I'm also attaching a speculative crew Dragon cross-section I created based on SpaceX images, to give an idea of the interior space.

thats a good layout and glad Apollo got in there for reference.

Blue Origin and DC fans how about some input?

[BrightLight]

DC scaled to rest of the vehicles.

I do believe that is the HL-20.... I know splitting hairs.

nit, nit,nit - of course you are correct, however I scaled it to the Dream Chaser spec of 29.5 feet/ 9 m.

It's always nice to see things side by side

[rmencos]

Not as nice as above, but here's another side by side from the Liberty presentation with Almaz.  I added Dragon (eye-balled the scale).

Ronsmytheiii:  believe I have made a monster thread here.  I posted last night and this morning "dreamchaser comparison.jpg (1846.82 KB, 2200x2925 - viewed 415 times.)" 

that's alot of interest in a few hours.

CAn someone add a scaled approximateion of Liberty capsule to that for comparison?  Or will it have approximately Orion's dimensions?  I think it'll have systmes commonality with Orion, but I don't know about it's external dimensions, and how they scale with the others.

Also, imagine how much habitable volume Orion would have if it had Dragon's sidewall angle instead of Apollo's?  I believe I read somewhere that Orion actually doesn't need the steep wall angle that Apollo had.  The angle of Dragon's would be fine, even at BLEO velocities.

The Orion dimensions and CCM shown above are about the same.  The missions LEO and BEO are different so supplies will change.   

Did you read the thread on the CCM?

The differences in the outer mold lines of the SNC Dream Chaser and the NASA HL-20 are not large. Cockpit windows, I think the RCS and maybe the entry/egress hatch might be different.  Thanks to Dr. Mordrid for the cutaway.

[rmencos]

Thanks.  I hadn't noticed the squeegee man on the HL-20 windows before.

[BrightLight]

Thanks.  I hadn't noticed the squeegee man on the HL-20 windows before.

Its still not clear to me where he is on the elevator, or does he get strapped on for the ride?

oh thats a nice cutaway......

Actually, it started with simonbp posting a photo of a cutaway from a presentation over a year ago. It was off-angle, blurry etc., so I did my graphics kung-fu to correct the perspective, rotate,  sharpen, re-draw and otherwise make it more presentable.

Consulted with BrightLight about a smooge to his images levels for the cutaway. Re-post attached.

[BrightLight]

Now all we need to do is put Korelev in the cockpit 

[Rocket Science]

Ya done good Doc...

I thought the Liberty capsule was going to be smaller then the CCM, and that they were just using the CCM for tests as a cost savings decision.

Are you sure that's an image of the Dream Chaser test article and not the HL-20 mock-up that was shipped to Sierra Nevada?

The bottom image is the HL-20 mockup, the middle image is of unknown provinance and is most likely an intermediate design, and the cutaway is several year old vintage DC. Getting up to date DC images in the right orientation is problematic, it would great to have a solid works file to run the images. That being said, the size and general mold lines hold true.
