Nordic Journal of Botany, Volume 2026, Issue 1, January 2026.Dispersal units that continuously rotate while falling purely due to aerodynamic forces are called autorotating dispersal units. Single‐ to multi‐winged forms of autorotating dispersal units occur in nature. The dispersal unit of Getonia floribunda Roxb.

Low Reynolds Number Airfoil Evaluation for the Mars Helicopter Rotor
Proceedings of the Vertical Flight Society 74th Annual Forum, 2018 The present research provides a performance comparison between several low Reynolds number airfoil profiles for the Mars Helicopter. The low density of the Martian atmosphere and the relatively small Mars Helicopter rotor result in very low chord-based

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper focuses on the resilience improvement of the distribution network with high‐penetration new energy under compound temperature–precipitation events (CTPEs). A prediction model of CTPEs‐sources/load based on coupling analysis of meteorological–electrical is proposed to provide data support for subsequent planning research, and a double‐layer ...
