Abstract : Results of a second investigation of the shockless lifting airfoil No. 1, performed in the improved NAE high Reynolds number 15 inch x 60 inch two-dimensional test facility, are presented. Better agreement with theoretical design conditions is demonstrated. Off-design characteristics for several Mach numbers are analysed, particularly with regard to maximum lift, buffet and drag divergence. (Author)
