PairTilt: Design and Control of an Active Tilt‐Rotor Quadcopter for Improved Efficiency and Agility
PairTilt is an actuated tilt‐rotor unmanned aerial vehicle capable of active shape reconfiguration, balancing simplicity, efficiency, and agility. Its H‐shaped frame incorporates pairwise tiltable rotors, which reduce gyroscopic torque and decouple key dynamics, enhancing maneuverability and reducing drag.

Predicting Performance of Hall Effect Ion Source Using Machine Learning
This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

Bioinspired Design, Fabrication, and Wing Morphing of 3D‐Printed Magnetic Butterflies
Inspired by the remarkable flight of monarch butterflies, lightweight, 3D‐printed magnetic butterflies are fabricated that mimic natural wing morphing without embedded electronics. By varying size, vein patterns, and laser energy in powder bed fusion printing, how these factors enhance deformation efficiency is shown.
