Re: [Fat_Ed] Mission to Outer Space
In reply to:
would a chute open in space?
It sure will, just very-very snively. Remember, that "space" at 120,000ft is not real space where spacecraft and planets orbit, it is still atmosphere with density of air of about 1/200th of standard density. Nothing proves better that there's still some air out there than the fact the balloon weighing perhaps a ton or more is able to
float in it.
At 1/200th of normal density, it'll take approximately 14x more speed to produce the same dynamic pressure as parachutes experience at low altitudes at regular speeds. (this is because dynamic pressure is proportional to the square of speed and directly proportional to density, and 14*14 ~ 200.) Jumping in still air, it'll take 14x longer delay to achieve approximately the same initial dynamic pressure as on normal jumps, so a 42s delay "there" would be like a 3s delay "here".
The ram air cells will "inflate" just like "here" except there won't be much air in them, but the dynamic pressure at superhigh speeds will be just like "here" - spreading the cells, tensioning the lines and fabric, giving the airfoil its shape. Once Felix achieves sustained flight, he'll glide at about the same glide ratio as canopies normally do - just 14x faster. So, for example, 30mph becomes 420.
Felix flying a parachute at 420mph in space... - now, THAT would stir a tsunami in our fabulous BASE Community notorious for its tender love to Felix!!!
