HRL Laboratories proof-of-concept delivers quiet, reliable propulsion for marine applications similar to the fictional approach used in the 1990 film “The Hunt for Red October.” Designed for DARPA, ...

To this end, the defence research organisation has launched the Principles of Undersea Magnetohydrodynamic Pumps (PUMP) programme, a 42-month effort aiming to build on the success of MHD at small ...

Summary: A groundbreaking development (that ended up being an April Fools joke…) for the Virginia-class: a story about a magnetohydrodynamic (MHD) drive system. The Virginia-Class Is Getting a Big ...

KOBE, JAPAN — In the beginning was the oar, a crucial if low-tech invention that served as the prime engine of naval propulsion for uncounted millennia. The next great advance was the sail, the ...

The compressible Navier-Stokes and magnetohydrodynamic (MHD) equations form the cornerstone of fluid dynamics when accounting for both variable density and the influence of magnetic fields. The ...

Abstract: Proposed missions such as a Mars sample return mission and a human mission to Mars require landed payload masses in excess of any previous Mars mission. Whether human or robotic, these ...

Almost all satellites have some kind of thrusters aboard, but they tend to use them as little as possible to conserve chemical fuel. Reaction wheels are one way to make orientation adjustments without ...

MALIBU, Calif.--(BUSINESS WIRE)-- HRL Laboratories, LLC has demonstrated proof-of-concept on a unique approach to achieve a silent pumping system that replaces traditional mechanical moving parts with ...
