In this paper, an attempt was made to obtain the aerodynamic performance of a Hex-rotor unmanned aerial vehicle with different rotor spacing.The hover efficiency of the Hex-rotor unmanned aerial vehicle is analyzed by both experimental tests and numerical simulations.First, a series of index to characterize the aerodynamic performance of the Hex-ro
Rapid qualitative research (RQR) studies are increasingly employed to inform decision-making in public health emergencies.Despite this trend, there remains a lack of clarity around what these studies actually involve in terms of methodological processes and practical considerations or challenges.Our team conducted Toddler a global RQR study during
