ABSTRACT	This report shows the results of the second two-dimensional transonic wind tunnel testing for new ATIC airfoils. This test was the result of cooperative work between ATIC and NAL and was conducted at NAL 0.8m×0.45m High Re. Number Transonic Wind Tunnel in 1999. The new airfoils, AK080E, AK100G, AK120G and AK120H, were designed at the second stage of ATIC airfoil research. AK100G/AK120G were obtained by modifying AK100D, which was designed at the first stage, in order to achieve high Clmax about Mach number 0.6. AK080E was made to accomplish high Clmax and low Cm0 by adding the contour change to AK080A, which was designed at the same stage as AK100D. And AK120H was redesigned in order to decrease the Cm0 of AK120G. In this wind tunnel testing, the effects of the improvements of these new airfoils were confirmed.
