ABSTRACT	Preliminary wind tunnel tests of a Bent-Nose Biconic were conducted in the NAL 1m×1m blow-down supersonic wind tunnel to evaluate its aerodynamics in the moderate supersonic rang.Aerodynamic data at attack angles of up to 50°was obtained for a 30°bent-sting.A flow-separated zone on the rear side of the body was observed by surface pressure distribution and oil-flow tests.Estimates based on Newtonian flow theory were not accurate when the attack angle was small for this rather slender configutation.
