News QM -1 World Largest Solid motor - test firing March 11

[dman]

I can't imagine trying to hold that thing in place with all of that power. I suspect some HUGE bolts.

Dont laugh......

It actually happened to one of the early rocket programs

In 1952 Viking no 8 broke lose during a test firing and rose to 4 mles before
the engine was cutoff...............

I think the use of solid rockets on manned spacecraft still causes concern, regarless of the upgrades.

Cool video. Are the SLS SRBs non-reusable, or will they also have chutes like the STS ones?

The new SRBs are expendable, it's apparently cheaper that way than to refurbish them.

I'm sorry, but the title's misleading... the largest solid rocket motor in the world was fired in the '60s: the Aerojet AJ-260-2, a 21.6 foot diameter, 60 foot long, 4 MILLION POUND thrust engine designed to replace the Saturn 1B first stage.

Imagine the epic Darwin award you could win with a sixpack of beer, a roll of duct tape, and one of these suckers.

Marshmallows.

 

[dman]

Marshmallows.

Nah just paint a Confederate flag on it

Some Good 'OL boy will want to take it for ride..........

 

[N_Molson]

I'd fire one equipped with an accelerometer straight vertically. Just for the fun of seeing how much Gs it can take before breaking apart.

I heard some rumors that they will be changing the nose cone to be more inclined with the main rocket body

Hardly surprising, since a more aerodynamic nose cone could result in a few dozen kg more payload at the same nose cone mass.

Well... actually they blow the PICs in the bolts after the PICs in the SRB ignitors...

Here's an episode of Mythbusters waiting to be done :rofl:

Try to find Smash Lab's Runaway Trailer episode (Season 1, episode 9), where they try to use various solid rocket mechanisms for wheeled vehicle emergency brakes, which is all hilarious until they almost burn themselves up with a misfire (not as funny but still funny because no one gets hurt). A healthy reminder that rocketry is very dangerous, even under the guidance of highly experienced and skilled experts and all precautions taken.

Just because someone gets hurt doesn't mean it isn't still funny.

MTV had an entire TV series based on the premise in fact.

 

[Astro SG Wise]

When exactly is the burn started?

 

[DaveS]

When exactly is the burn started?

Targeting at 9:30 am MDT (11:30 am EDT) ignition.

 

[Urwumpe]

Targeting at 9:30 am MDT (11:30 am EDT) ignition.

Or 16:30 CET.

Why don't we have a timer for it?

Because the person who usually puts timers in different places is occupied with his work.

I totally agree, but...well, its a pretty big rocket engine,

If you get hurt by that, it's sorta all or nothin' :lol:

 

[Prowler901]

Jeez, the drop outs are ridiculous. But, that was pretty amazing.
