New space program's launch vehicle oscillates at 12hz...even at 4 g's!

The link above has more info, but in a nutshell, the Ares I's resonant frequency is 12hz, due to the upper stage's rocket. This is causing some serious concern as to astronaut's safety, and for good reason... they'll be hitting about 4g's while oscillating at that frequency. Can we say "shake the **** out of you"?

Sounds awful - I'm sure the engineers will work out a way to solve the problem though. I only had time to glance over the article, but is it known what amplitude those oscillations would occur? (Not sure if I'm stating that accurately, as I'm perhaps thinking of oscillations from a literal wave propagation standpoint alone, and not in this type of application which I am unfamiliar). I would think that minute oscillations would feel more like a vibration and larger ones would really do some damage to a human's innards at that G-force.

Can we use Rosie's thighs as a dampening device to counter the vibrations?

 

[Halon451]

Ha! Strat, you certainly have no love for Rosie do you? As it should be. The only problem with your solution is that the dang rocket probably wouldn't even be able to get off the ground!

What, about 400 pounds a pop? I say tie them with ropes, then the 'nauts can just cut them off when out of grav pull.

How about Dolly Parton?

How about Dolly Parton?

Used for cushioning the landing upon re-entry.

 

[stratman]

You know guys....There's something about Dolly, back in the day....whew! She could plow a field that one.

 

[Halon451]

You ain't just whistling dixie my friend... I still remember seeing those oversized mammaries bouncing around on Hee-Haw back when I was a little kid, mesmerized in front of the TV...

Yeeeeees sireeeee boob, er I meant Bob, sorry, Dolly has that effect on me.

Erin - this is what happens when you leave such an intelligent topic unattended...

You just beat me to that, sorry Erin, something about Friday afternoons.

You guys and your filthy minds!

I meant her singing. The frequency could counteract the bad harmonics.
(Really, that's what I meant..... )

She was a singer??

AWWW! YEAH! RIGHT!!! You like her vocal chords, that's it, right, the roundness of her timbre, the way her vocal cleavage projects her range, yes, you're soooooo mesmerized by the fullness of her..........talent.

 

[Halon451]

Ha... LOL. You clever, clever caveman.

Didn't Pamela Anderson remove significant amounts of silicon?
Now this could come to use

Guys, please quit crapping on my posts. This is ridiculous. I expect more out of the community here... guess I should've known better. Bunch of immature kids.












J/K

Carry on!

Ha you engineers don't stay far behind!! I wonder how many of our ideas: Dolly, Rosie, Pamela variants, silicone capsule protectors, etc, etc donated by the fertile minds of depraved audioholics will mysteriously find their way into space vehicles in the next 10 years and I'm willing to wager Halon's salary for the next 10 that if we search the patent office the name E.Hardison will appear plenty of times.


Oops my mind was percolating: Why don't we use Dolly's brassier as a catapult for low orbit sats??? Ha see another great idea, to be borrowed by Mr. E.H.
