SpaceX Sets LAS Integrated Test Fire
« on: 04/25/2011 11:16 pm »
SpaceX Media information:
The Dragon's side-mount launch abort system will be designed and built to the point of a full-duration engine firing on the ground by next May.

Today is April 25th, 2011 @ 6:13 CST

The Question:

Is 13 months and five days enough time to design, go through PDR, evaluate, fix, go through CDR, build and test by 31 May 2012 at 11:59PM?

Tony Stark madness.  Love him or hate him, Musk has "gravitas".

Wanted this in a separate thread so we can see who is the closest to being right.

Waiting to see who has "gravitas".

You can talk about all the great things you can do, or want to do, in space; but unless the rocket scientists get a sound understanding of economics (and quickly), the US space program will never achieve the greatness it should.

Is that May 2011 in the SpaceX calendar or the Gregorian calendar?   ;)

They're being a bit loose with the word "system" and what is expected.  A more accurate statement would be:
Quote
Key components of the Dragon's side-mount launch abort components will be designed, test articles constructed, and a static-fire test of the engine by next May.

From the SAA, Milestone 9, May 2012:
1) Initial static-fire testing of the engine.
2) Initial testing of the tank.
3) Initial testing of key components.

My bets are on Mid September.  ;)

Side bets taken on who Musk blames it on when they don't make it.  It's never his fault.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

The Question:

13 * 2.4 = 31.2 months
5 * 2.4 = 12 days

giving 31.5 months (2 years 7.5 months)

Which is December 2013.

Does anyone have a sense for the long pole(s) in the SpaceX LAS engine test? From my completely naive perspective, it seems like it should just be a straightforward modification of their Draco engines. What takes such a long time?
Someone is wrong on the Internet.

Draco is only ~90 lbf of thrust. The LES/landing thrusters are going to need many times that.

It wouldn't surprize me if the abort system isn't already mostly designed.  My bet is that the full-duration engine firing will be December of 2012.  Although I rather that he's right and can pull it off in May 2012.

Heh.  My parents live in Waco.  SpaceX's facility is actually not far at all from downtown.  Everyone knows when they are testing testing. ;)

That said, most think its cool  8)

Oh yeah, no doubt.

I'll put my money on an early completion of almost all of the early milestones. They may not make the full up test by May 2012 but not for a lack of trying.

It's cool because it's money and jobs - something that can always move as we have seen in many other areas. Just a fact.

I'm sure it would be annoying to those living closest to the stands, but those are the realities of life.

LOL! That's a good one. Never been to Texas have you? We're 15 years into a plan to meet EPA clean the air standards in Dallas, with no visible progress, and with our "beloved" Gov. Perry and the other incorrects in Austin fighting the EPA all the way.

If any SpaceX dollars would flow into Texas as a result of this test, you can bet that the Texas Council on Environmental Quality will be Elon's best friend, and the locals can choke on his exhaust for all they care.
