So arc reactors are capable in that universe, but not the ability to spin those rotors another 64rpm?

The helicarrier isn't current technology, why should it be constrained by current technology?

Bad news, idiotmitter, we're watching a movie about superheroes and no one gives a flying fark if any of it is physically possible as long as we get plenty of HULK SMASH!

These new-fangled comics are just too complicated. Back in my day there was a thing called "suspension of disbelief". It made science fiction possible, and we were glad to have it.

The dumbest thing about the helicarrier is the cloaking. Something that huge would have a massive heat signature and might even disrupt weather patterns. Cloaking would be pointless.

One neat thing about the HeliCarrier, though: it absolutely refuses to allow less-than-shiat-hot pilots to land on it... since its forward port lift rotor is right in front of the landing runway, meaning if you miss your hook you get sucked into the blades.

Yeah, it's not so much the sound itself as it is the magnitude of the pressure waves passing through your body from the sheer loudness. On the bright side, you wouldnt need to worry about kidney stones.

Any links to info on this?  The only thing I've ever heard is that it's an urban legend.

0100010: Any links to info on this?  The only thing I've ever heard is that it's an urban legend.


The "brown note" part is an urban legend. There's not a particular frequency that will cause people to crap their pants. The effect I'm describing would happen with any sound if you played it at hundreds and hundreds of decibels: shock waves passing through a mostly-liquid medium like the human body have disruptive effects. It's sort of like being shot with a rifle bullet.

Most of the stories I'm finding on the XF-84H include "intense nausea" as a symptom of exposure to the noise. Make of that what you will, but I imagine in at least some of the cases, "intense nausea" was a far less embarrassing way to report "nearly shiat myself". I'm looking for a link that will back up the bowel-loosening effect--I first heard that from an aero engineering professor who used to evaluate experimental projects for the Air Force, but the Thunderscreech was before his time.

Nothing concrete, no. I recall Mythbusters doing an episode on it, but they focused more on the freq of the sound, and not on its power (as it's inaudible, I don't know that 'volume' is the best term). I can tell you (but cannot provide confirmation) that systems of high power have been tested with promising results.
 
2013-06-28 06:21:17 PM  
Mythbusters covered the brown note, like, a hundred years ago. Busted, as one might expect.

Brown guitar tone, on the other hand... I believe Prof. E. Van Halen has been working on that project.

Ground crew reported that wearing standard ear protectors "made no difference" and a person standing some distance from the airplane was subjected to rapid-fire shock waves. The shock waves acted on the body, causing spasms, nausea and loosening of the bowels. Even epileptic seizures were reported.

Sadly that's not sourced but from what I can tell it's mostly quoted from an article in an old issue of Air & Space. I also saw an unsourced reference blaming the noise from the Thunderscreech for inducing miscarriages in pregnant women near the air base! (Not sure if I'd buy that one 100%, but whew)

A Chinook's "C" model's rotor blades rotate at 235 rpm. "D" model rotates at 245 rpm. We were not authorized to wax the rotor blades, but occasionally on the wash-rack, we would because the pilots loved the rotor "POP" it produced as the tips exceeded the sound barrier. It also increased useable engine power.
