... Depends on what handwavium you're using. If your drive is one that won't simply be quenched by atmosphere and isn't excessively dirty you can run it at...
... Don't forget about space fountains. The key to fusion technology is high-temperature superconductors, the same thing required for space fountains. These...
I am fascinated by the Fission-fragment propulsion system http://en.wikipedia.org/wiki/Fission-fragment_rocket but performance numbers are hard to come by. ...
... My understanding is that the problem with scramjets is the difficulty of getting fuel to combust with the air at supersonic rates of flow. If you are...
... Yes, though I've noticed that with propulsion systems in general there seems to be an inverse relationship between specific impulse and mass-flow/thrust. ...
... There are lots of nice 1/700 models out there and some of the sets are quite cheap but much of what I'm trying to integrate with (e.g., DP9's GK stuff) is...
... Yes, i've seen the web page and i find it incomplete. What i would like is a worked example. For a volume of X an acceleration of Y, and a ratio of Z,...
... Just a reminder that _you_ were inviting feedback. Thanks for the invitation. I'll also note that in the time it took you to count the 47 "worked ...
... Interesting reading. Off the cuff, if the vessel was made from structurally sound cells like a sponge or honey comb, how much would that impact the hull's...
... I think I misunderstood the question. You've read the webpage, but want to know what I meant by "derived the formula for stability empirically from the...
ok . so the formula is derived from traveller rules .. do these rules anywhere give realworld reasons for the formular (like for instance: "we used the fomula...
it answers part of my qiestion - thank you .. 8-) but sice it is derived from traveller, does traveller give any information on what they used to achive...
... Indirectly, yes. It was my attempt to reality-check the Traveller rules. ... Based on conversations with Loren Wiseman, and his "From the Editor" columns...
... This was the issue I was discussing with Eric Ueber, since I am not a structural engineer. As I understand it, however, the "thin-walled cylinder" is a...
If you're like me you switch to NPR whenever Rush Limbaugh goes to commercial. Locally NPR was boadcasting _The Story_ hosted by Dick Gordon. His guest was...
... How about a starship with a fission reactor in back that is shielded for neutrons in front but allows them to fly free in back? Since these neutrons would...

... According to my copy of Propulsion Systems for Space Flight (1960), 85% of the energy from fission is in the fission fragments, only about 15% are in...
... What if you applied this to a setting like Traveller with anti-grav so the hull is never stressed to more than 1g? -HJC Explicit in GT, but I don't think...
... Depends on the design. From what I recall reading about dusty plasma fission fragment thrusters, they're mostly heat-limited. ... ACMF isn't the same...

... This won't work, because of centrifugal force (or whatever the heck it's supposed to be called, technically). With a traditional turbine hub, centrifugal...
