Study of the Propeller with Small Blades on the Blade Tips
Journal of the Society of Naval Architects of Japan, 1987 The author performed cavitation test (cavitation observation, propeller open test, fluctuating pressure measurement and noise measurement) in uniform flow to compare the characteristics between the conventional (original) and the propeller with small blade on the blade tips (bladelet propeller).From these test, it was suggested that the reduction was ...

Advanced Functional Materials, EarlyView.CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1

NATURAL FREQUENCIES OF TUNED AND MISTUNED BLADED DISCS ON A SHAFT
TASK Quarterly, 2006 The dynamic behaviour of a rotor consisting of two tuned and mistuned bladed discs on a solid shaft is considered. The effect of the shaft’s flexibility on the dynamic characteristics of the bladed discs and the coupling effects between the shaft and ...
