The aerodynamic performance of a morphing airfoil is numerically and experimentally investigated. designed based on macro fiber composites, capable trailing edge flapping during 10–90 Hz with maximum amplitude 0.55 mm. A numerical model flexible deformation walls the experiment established to precisely restore actual dynamic instead segmental explore transient high-frequency flapping. drag coefficient reduced by 2.07% at frequency (ff) 37.5 compared rigid airfoil, while lift increase 4.8%...
The third-generation semiconductor material gallium nitride (GaN) has attracted more and researchers attention due to its excellent performance. In the processing of GaN wafer, surface/subsurface damage would inevitably generate after diamond abrasive lapping. Chemical mechanical polishing (CMP) with soft is widely used remove obtain ultra-smooth wafer surface. However, traditional CMP very low removal rate (MRR) because high hardness chemical inertness wafer. To improve MRR, hybrid-field...
