Abstract: This paper proposes a class of velocityfree attitude stable controller using a novel finitetime observer for spacecraft attitude tracking, which explicitly takes into account control input saturation to assure fast and ...

Abstract: An improved passage-flow turning model (IPTM) was developed in this study to design high-performance forward-curved blades for squirrel-cage fans. The flow separation in blade passages and the corresponding fan performance ...

Abstract: The inverse design method for turbomachinery can directly acquire a blade geometry with specific aerodynamic parameters, such as pressure loading on the blade surfaces. The difference between the inverse design and direct ...
