内容記述 | This paper focuses on numerical and experimental research for designing low-noise slat on a simplified high-lift configuration model (OTOMO). Slat noise is known as a dominant noise source from the aircraft at approach condition and noise reduction is required for future aircraft without any aerodynamic penalties. Two types of noise reduction devices are considered. First device is a slat cove filler (SCF). From the previous studies, SCF seems to have an effect on reducing broadband noise by forming substantially continuous shape instead of a slat cusp configuration. Several previous studies indicate that noise reduction can be achieved by maintaining the aerodynamic performance. In this study, further investment on small difference in SCF geometry is discussed experimentally as well as numerically. The best SCF shape maintains the aerodynamic performance and substantial noise reduction is achieved. The second device is called thin slat (TS). This device maintains the leading edge radius of the baseline slat and cusp region is shaved off to avoid separation from the cusp. Interestingly, the aerodynamic performance, such as maximum lift coefficient and stall angle, will be maintained while noise reduction is achieved. These results indicate that lower surface slat could be designed for the low noise configuration without aerodynamic penalties. | |||||
