Review of Electrically Powered Propulsion for Aircraft [PDF]

2018 53rd International Universities Power Engineering Conference (UPEC), 2018
This paper presents a review of the state-of-the-art in aircraft electrical propulsion technology. A comparison is provided of differing propulsion mechanisms such as propellers, open fans, ducted fans, multi-stage rim driven fans and distributed thrust designs and their suitability to particular flight profiles and mission applications.

Magnetic Flux Guides by Material Extrusion

Advanced Science, EarlyView.
Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface

Advanced Science, EarlyView.
A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...

Thermally Programmable Two‐Port Non‐Hermitian Acoustic Metastructure for Broadband and Direction‐Dependent Absorption

Advanced Science, EarlyView.
A thermally programmable two‐port non‐Hermitian acoustic metastructure is presented, where temperature acts as a non‐geometric tuning variable. Thermal modulation reconfigures impedance matching and loss‐leakage coupling, enabling exceptional‐point driven, broadband, and direction‐dependent sound absorption without requiring geometric reconfiguration ...
