The Control Efficiency Analysis of Asymmetry Transmutation forFolding Wing Morphing Aircraft

Hangkong gongcheng jinzhan, 2018
Folding wing morphing aircraft can alter their shape largely which causes the aerodynamic parameters change significantly. A control scheme that using asymmetric morphing as a control input is proposed in this paper to investigate the control efficiency ...

Relative Humidity Influences Aureobasidium pullulans Degradation of Polyester Polyurethane Foam

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
The plant pathogen Aureobasidium pullulans' ability to degrade polyurethane foam is impacted by Equilibrium Relative Humidity (ERH). These impacts can be observed through foam weight loss, scanning electron microscopy (SEM), fungal growth, and cutinase gene expression.

Dynamic Modeling and Simulation of Morphing Wing Aircraft Considering Rigid‐Elastic Coupling Effects

International Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 65-85, March 2026.
ABSTRACT During the morphing process, the dynamic modeling of the morphing wing aircraft presents the characteristics of rigid‐elastic coupling effects, moving boundaries, and low computational efficiency. Meanwhile, parameters such as aerodynamic forces/moments, center of pressure, center of mass, and moment of inertia would also change significantly,
