Flow Analysis around Tilt-rotor Aircraft at Various Tilt Angles
Journal of the Korean Society of Visualization, 2011 Abstract. Tilt-rotor aircraft can be used in various fields because they have the capabilities of the ver-tical take-off and landing and the high-speed cruise flight. In the present study, the flow analysis of atilt-rotor aircraft is conducted at various tilt angles.

Dynamic Simulation of Tilted Rotor Quadcopter
International Journal of Innovative Technology and Exploring Engineering, 2019 Application of quadcopter unmanned aerial vehicle (UAV) has already become common today. As the name suggests, quadcopter has four rotors and these rotors can be classified into two types: fixed and tilted rotors. The maneuvering of quadcopter using the fixed rotor is achieved through the thrust differential.

Advanced Functional Materials, EarlyView.Electrochemical abuse transforms thermal runaway behavior in lithium‐ion batteries. Through systematic decoupling of degradation mechanisms, this study reveals that lithium plating lowers the onset temperature by 10 °C, electrolyte consumption delays high‐temperature reactions, and capacity fade reduces total heat generation. These mechanistic insights
