Design engineers routinely rely on bolted joints, yet most guidance focuses on axial stiffness—often overlooking moment (pitch) stiffness, which can dominate compliance in ...

After nearly two decades of focused development, a Chinese research team has finally proven its streamlined thrust-vectoring concept in real flight, using a high-speed unmanned aircraft as the testbed ...

Abstract: The eddy currents induced in a thrust bearing result not only in a power loss of the system but also in phase lag and a decrease in magnitude of the magnetic force. Therefore, an accurate ...

Abstract: The aim of this paper is to study different permanent magnet (PM) bearings geometries based on PM rings with a minimum volume of PM for a given load. Simple and general scaling laws (SCLs) ...
