内容記述 | A transonic wind tunnel test of an HLFC (Hybrid Laminar Flow Control) wing model with a new leading edge suction system incorporated with a natural laminar flow airfoil was conducted to check mainly the drag reducing effect of the suction system in the transonic Mach number range. The test confirmed that the system works well in both design and off-design conditions, resulting in significant drag reduction in a wake drag with even a small amount of suction. Besides the drag reducing effect, it was found that the system produces considerable lift increase for some suction quantity ranges in a wide range of test Mach number. The lift increment generates a higher L/D (overall wing Lift/overall wing Drag) value than that which may be expected from the drag reduction alone. | |||||
