Popis: | The results of balance aerodynamic tests on model straight wings with smooth and ribbed surfaces at an angle of attack α=−4°–12°, Mach number M∞=0.15–0.63, and Reynolds number Re∞=2.4·106–3.5·106 are discussed. The nondimensional riblet spacings+, which determines the effect of the riblets on the turbulent friction drag, and the effect of riblets on the upper and/or lower surface of a straight wing on its drag, lift, and moment characteristics are estimated. |
