The magnetohydrodynamic (MHD) drive certainly sounds like something out of science fiction — using an array of magnets and electrodes, this high-tech propulsion technology promises to silently ...

Now, 30 years after the movie, Darpa is working on a marine propulsion system similar to the "caterpillar drive" described in the movie. Called a magnetohydrodynamic (MHD) drive, the system has no ...

The “caterpillar drive” in The Hunt for Red October allowed the sub to travel virtually undetected through the ocean, but real examples of magnetohydrodynamic drives (MHDs) are rare.

Sustained hypersonic propulsion is a complex problem due to the high temperatures and velocities associated with these flows. In high-hypersonic flow regimes, combustion is limited by low residence ...

NASA's MHD patch technology ... the craft's trajectory. The system, more straightforward than traditional hypersonic craft control methods such as chemical propulsion or adjustments in flight ...
