http://www.flightglobal.com/blogs/hyperbol...ests-under.html http://www.space-travel.com/reports/Russia...engine_999.html -------------------- I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

There was mention some years back of a device that directly utilized the kinetic energy of the fissioning fuel for thrust, seems like that one was pretty unworkable. Wish I recalled more of the details. Like maybe a uranium foil was blipped with N, and the fission products spalled off the back
of the foil. Exhaust velocity was enormous, but the net thrust was extremely low. Recall Dyson's (son) assertion of how many possible thrust technologies there might be. That article sure left out many details. |
