| 摘要： | An extensive experimental effort was undertaken to document the performance of a low-aspect ratio hydrofoil with trailing edge blowing across a Coanda surface in a large water tunnel facility. This facility was the William B. Morgan Large Cavitation Channel in Memphis, TN. The hydrofoil model with a taper ratio of 0.76 was mounted through a load balance. A reflection plane provided for an effective aspect ratio of 2. The dual-slot configuration allowed for an investigation of thrust vectoring, and also presented an unexpected opportunity to offset the negative impact of excessive turning of the wall jet onto the underside of the foil. This report serves to document the experimental details of that effort for future experiments and document the types of data collected for validation of computational fluid dynamics (CFD) codes. The performance of the selected hydrofoil section shape is documented with six-component load measurements and detailed laser Doppler velocimetry measurements (LDV) taken in the wake of the foil. / NOTE: Final rept. 1 Oct 2000-30 Sep 2002. / Supplementary Notes: 01C5S00009; 01-1-5400-131, 02-1-5400-141. / Availability Note: Product reproduced from digital image.
