flyboy Posted August 13, 2005 Share Posted August 13, 2005 well you would need a big ass rocket if your gonna put a nuclear reactor engine in it and theres big risks if somthing goes wrong, if the rocket explodes or whatever then we all get affected by it Link to comment Share on other sites More sharing options...
CPL.Luke Posted August 14, 2005 Author Share Posted August 14, 2005 actually it was considered for the upper stage of the saturn 5, it would have been able to send people to mars if it had been done Link to comment Share on other sites More sharing options...
DV8 2XL Posted August 14, 2005 Share Posted August 14, 2005 At the suggestion of Theodore von Kármán and following a request of Gen. H. B. Thatcher, an Ad Hoc Committee of the Scientific Advisory Board met in the Pentagon to consider the application of nuclear energy to missile propulsion. The result was project NERVA SEE:http://www.astronautix.com/project/nerva.htm Link to comment Share on other sites More sharing options...

Thomas Kirby Posted August 15, 2005 Share Posted August 15, 2005 Did anyone ever produce a power-efficient drive based on any kind of electrical acceleration of any sort of matter? Link to comment Share on other sites More sharing options...
CPL.Luke Posted August 15, 2005 Author Share Posted August 15, 2005 yes, its ion propulsion, cassini went to saturn on it Link to comment Share on other sites More sharing options...
calbiterol Posted August 16, 2005 Share Posted August 16, 2005 Ion drives are extremely efficient - the problem is, they have very little power, but a LOT of exit velocity, so they don't produce any decent amount of acceleration. Link to comment Share on other sites More sharing options...
ydoaPs Posted August 16, 2005 Share Posted August 16, 2005 Ion drives are extremely efficient - the problem is, they have very little power, but a LOT of exit velocity, so they don't produce any decent amount of acceleration. but it is constant acceleration and they run for a really long time. they can go faster than a conventional rocket of the same mass, iirc.

flyboy Posted August 17, 2005 Share Posted August 17, 2005 they just acclerate really slow Link to comment Share on other sites More sharing options...
ydoaPs Posted August 17, 2005 Share Posted August 17, 2005 they just acclerate really slow "slow" is an adjective, not an adverb...try "slowly" ....."lolly lolly lolly, get your adverbs here....lolly lolly lolly, get your adverbs here..."...

insane_alien Posted August 17, 2005 Share Posted August 17, 2005 go to the forums at http://www.orbitersim.com and look under space maths and physics. it has been discussed ad infinitum. its also a really cool sim. Link to comment Share on other sites More sharing options...
calbiterol Posted August 18, 2005 Share Posted August 18, 2005 they can go faster than a conventional rocket of the same mass, iirc. After a certain point, this is definitely correct. I'm not sure if it is always correct, but when put into practice, this is most definitely true. Link to comment Share on other sites More sharing options...
vrus Posted August 29, 2005 Share Posted August 29, 2005 they just acclerate really slow I think its something like 0-60 taking 4 days ! Link to comment Share on other sites More sharing options...
