Drag Measurement of a 34 deg Swept-Forward and Swept-Back NACA 65-009 Airfoil of Aspect ratio 2.7 as Determined by Flight Tests at Supersonic Speeds

Abstract

The drag of a 34 degree swept-forward and swept-back airfoil was measured. The data was obtained by tracking rocket-propelled winged bodies moving at supersonic speeds. Comparison is made between results of similar tests of previous reports and of this report. Test results show that both the 34 degree swept-forward and swept-back airfoils produced lower values of zero-lift drag than the unswept airfoils. At Mach numbers 1.0-1.3, drag of swept-back wing was about 50% and that of swept-forward wing about 65% of drag of unswept wing.
