New from Monkeys Fly Out Your Ass
Safety Products Inc. !
The Personal Safety Sphere. For
airline disasters like the plane
breaking up in flight and jettisoning
passengers all over Venezuela at
30.000 ft. passengers can wear a
vest that contains an airbag like
inflation system that will
envelop the
human in a 15 foot diameter shpere.
The outer surface is made of a thin
skin of woven stainless steel like auto
airbags with a film or bladder inside,
and the human would be encased in
a fetal or sitting position by radiating
web of kevlar or spectra lines and rib
structure to center them in the
sphere. With the large diameter the
aerodynamic drag would be sufficient
to slow the decent rate to surviveable
impact speeds and the stainless bag
could take a pretty good hit a few
times before a puncture would begin
to deflate it. A small oxygen system
option could be supplied as an
option, it might be necesary to
provide a breathable atmosphere
with the nasty gasses of the
explosive used for inflation.
The applications are enourmous, the
portent vast and bewildering..the
creative mischeif, setting one off in
close quarters .. jumping off
mountains and rolling down... base
jumping..

You forgot to add that they would float too, but how do you propose to explosively fold a human body into the fetal position without breaking several bones in the process? |
|
| |
Could something that big provide adequate protection from exposure at 30'000 feet? |
|
| |
Not to mention the bag ripping. |
|
| |
Also, how much would a -sphere- slow the fall down? |
|
| |
Round and round we go... Hey, where are the breaks? |
|
| |
Well if the bag expanded into a blowup collage of all the bond girls from one of the bond films that featured this then it would be quite supreme... |
|
| |
I like the updated version........ alcaity |
|

I gave this one a fish because a while back I did some research concerning motorcycle protective wear, and found out that Alpinestars actually developed the personal airbag for motorcyclists ... with link ... although not COMPLETELY identical to this idea as a whole, the Title "Personal airbag vest" goes to Alpinestars. |

I checked out the Alpinestars page, it's cool but looks like it's a neck breaker with the head sticking out unprotected, along with most of the rest of the body parts, thanks for the comments, a five beer napkin calculation estimate for descent rate somewhere around 30fps in free fall, with an average sized load, say up to 190#, heavier folks would need a larger size. A small drogue to stabilize it so you wouldn't puke if the thing was spinning, small sports O2 systems are commercialy available, the explosive staged to prevent physical damage, but hey, I don't have time to build it, and wonder if there is any history of ideas from this site actualy being taken up by a commercial entity and developed into products? is it only a forum for the creative narcissist? |

You need to calculate the terminal velocity of the deployed bag. Due to drag, it is certainly less than with out the bag. |
|
| |
Its not the fall that kills you, its the sudden stop at the end. The bag would need rigidity to coushin the impact. This could be done by increasing the pressure inside the bag, but that would be painfull for the occupant. |
