In this paper, we focus on the assessment of the optimal design of the propulsion system of an energyautonomous Hyperloop capsule supplied by batteries. The novelty in this paper is to propose a sizing method for this specific transportation system, and an ...
This article presents an analytical micro-vibration model for magnetic bearing reaction wheels (MBRWs) based on a rotordynamics model combined with the active control loop. This model is validated employing a fullyactive Lorentz-type MBRW demonstrator and ...
Specific energy (i.e. energy per unit mass) is one of the most fundamental and consequential properties of a fuel source. In this work, a systematic study of measured fusion cross-sections is performed to determine which reactions are potentially feasible ...
The mechanism responsible for the production of energetic ions in the plume of hollow cathodes for electric propulsion is still an open issue. These ions are of concern to cathode and thruster lifetime, particularly for cathodes operating at high (>20 A) d ...
In this article, we combine experiments and theory to investigate the transport properties of anisotropic hematite colloidal rotors that dynam ically assemble into translating clusters upon application of a rotating magnetic field. The applied field exerts ...
Underwater swimming robots permit remote access to over 70% of the Earth's surface that is covered in water for a variety of scientific, environmental, tactical, or industrial purposes. Many practical applications for robots in this setting include sensing ...
A popular method to induce synthetic propulsion at the microscale is to use the forces created by surface-produced gas bubbles inside the asymmetric body of a catalytic swimmer (referred to in the literature as microrocket). Gas bubbles nucleate and grow w ...
An aerial vehicle, configured to transport cargo, and including a propulsion system and a foldable cage is described. The foldable cage is substantially linear while in a folded configuration, and substantially circular while in a deployed configuration. M ...
