Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Development of n‐type ZnAlInO Semiconductor Materials for Thermoelectric Generators in Aerospace Applications

ChemistryOpen, EarlyView.
Herein, the synthesis and production of n‐type ZnAlInO semiconductor materials is achieved utilizing sol–gel and cold pressing methods for fabrication in aerospace thermoelectric generators applications. The Seebeck coefficient and power factor values increase with the addition of template samples, reaching a maximum of −162.63 μV K−1 and 0.44 mW mK−2,
