resistance

[jtkirk1701]

if you had a tube. divided it into sections with a perferated walls between the sections. then put a blower on one end, and an exhuast blower on the other end. then placed the tube in a low gravity enviroment. would objects in the tube be held against the walls??? if you stand this on end and the walls become floors. would this not create some resistance for our astronauts to deal with. it would be continueous. would slow down bone deteriation. maybe you could almost stand???? could someone tell me why this would not work???

I think the problem would be getting enough airflow to provide a significant resistance. It takes a <b>huge</b> fan to do "static skydiving" on Earth, it would take a similar system to get something close to 1g equivalent in space.

I can't imagine it being very comfortable for the astronauts, or that they'd get much work done while it was on.

place the astronauts under rocket nozzles? <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <p>http://asteroid-invasion.blogspot.com</p><p>http://www.solvengineer.com/asteroid-invasion.html </p><p> </p> </div>

ok... why not just use centrifical force... now there is a new idea....<br /><br /><br /><img src="/images/icons/smile.gif" /><br /><br />

you are not trying for full gravity. the air must flow anyway. why not have it flow in one direction, (no jokes please).the flow of the air would be no more than normal. in a weightless enviroment a piece of paper would fall to the floor. this would cause the astronauts to always be working against a down ward flow of air, gentle though it is. that in turn should help work against bone deteriation.<br />i suppose that one day they will invent gravity plating or something. for right now there is no resistance ...other than when your strapped to a machine. at least your skellital musicals would have some force working against them. this could help on long duration space flights????0<br />

Beans must be a staple diet on the space station. Drop your knickers and you become a rocket. <div class="Discussion_UserSignature"> <p>http://asteroid-invasion.blogspot.com</p><p>http://www.solvengineer.com/asteroid-invasion.html </p><p> </p> </div>

Swimming would work, especially if the cabin air is "thick" [14 psi, not the thin 5 psi of Apollo]. But it would be easier to purse your lips and blow yourself over to a handhold.<br /><br />

How much time would an astronaut need to spend in a simulated gravity environment to counter the negative effects of 0 g? If they could design some sort of exercise pod, (perhaps the astronaut pedals, similar to a bike), which causes the pod to spin, thus producing a temporary artificial gravity. This would be much smaller and cheaper than spinning the entire ship, and be done while they are doing their normal exercises. Thoughts?
