Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

A Two‐Stage Optimization Approach for Selecting Electric‐Flight Airports

Networks, EarlyView.
ABSTRACT The decarbonization of short‐haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short‐haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative.

Trait‐associated pathway links plant diversity to litterfall phenology in a seasonally dry tropical forest

Oikos, EarlyView.
Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...

Application of 3D scanning technology in Royal Malaysian Air Force Industrial Revolution 4.0‐based aircraft maintenance

IET Networks, EarlyView., 2022
Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.
