Plasma Balls and Fire Sheaths
"In a remarkable series of theoretical studies and engineering tests, scientists at the Rensselaer Polytechnic Institute in New York have come up with a way to protect aircraft cruising at 30,000kts (55,550km/h) from the effects of friction with the earth's atmosphere. David Baker PhD examines the idea behind the concept and reviews progress toward an entirely new generation of flying vehicles threatening to outdo anything yet projected by science fiction.
Read on at http://www.aeronautics.ru/mach50.htm
I know that is definitely out there, but very interesting none the less.
Imagine cruising to a target at Mach 30... I know this won't happen
anytime soon, but, it may happen down the line... |

| MHD was also used on the "Red October" wasn't it? |

This is more of the "plasma magic" that brought us the "active plasma stealth" pipe dream.
Honestly, does:
seem plausible to anybody here? |

| What kind of propulsion has the Aurora? (If it's true) |

Currently, the Aurora uses engines that run on the imagination of aviation writers everywhere.  |

| Rumor has it, the Russian engines are a bit better. |

| Here's the problem, Magneto means magnet, hydro means water, and dynamic means moving, put them together and you get magnet-moving-water. That illustration and essay or whatever you call it don't involve magnets moving water. |

| it doesn't have to be water. Does it involve any liquid at all? |

The "LightCraft" experiment was a small spin stabilized test vehicle (about 6 inches in diameter) that rode up a laser beam. Interesting experiment, but they found that atmospheric dispersion and wind limited it's practicality. Nothing remotely "magnetohydrodynamic" about it.
Most of the links from that page are dead. |

Salute!
The MHD concept that is most interesting went "black" in the mid-70 period.
It wasn't intended for propulsion, but to generate a few megawatts of electricity for a short period of time.
Apparently, the plasma going out the exhaust passed some grids that stripped the electrons or other doofers and developed an immense potential between the grids. It was alleged that one of these things about the size of a 2,000 pounder could crank out a few megs of juice for a few seconds.
The alleged use of the electricity was to power a huge laser. So we all started to think we could have the "real" Colonial Viper's weapons for our newly-minted USAF Vipers. Just point and shoot. No lead angles, a half a mile range or more, and could be used for ground attack.
Wonder what ever happened...... |

Hey Gums!
The plasma between grids deal sounds like the same kind of tech in an ion drive. Which is what powered NASA's Deep Space 1 http://nmp.nasa.gov/ds1/. What was really crazy is supposedly the TIE in George Lucas' TIE fighters stands for "twin-ion engine"... Of course the DS1 ion engine only works in a vacuum. Air has an annoying tendancy to conduct electricity once the voltage gets high enough (ala lightning). |

Hmmm. Sounds like a generator I read about in the 80s but the idea was to use it to power a railgun on an armored vehicle. |

| 'Leady, leady, leady oooohhh Starbuck, pulsed power machines. A pulsed power generator can be used to power: a laser, an electro-magnetic railgun, or an EM pulse weapon. Sferrin are you pointing at the Sandia Laboratory Hermes III or Z-machine?. An EM railgun was also tested by Sandia, this could reach a muzzle velocity of 6 km/s ( 19.672 ft/s), a 105/ 120mm tankgun reaches 1.700 m/s (5574 ft/s). But they wanted to use this kind of guns to shoot down ballistic missiles. Funny, in 1992 the USAF revealed that in the B-2 plasma stealth together with electro-static technology was used to lower RCS and drag. |
