Abstract:

A wind tunnel test was conducted to determine pressure distributions on a two-dimensional airfoil with pylon-mounted stores at Mach numbers from 0.70 to 0.95 and angles of attack from 0 to 14 deg. Four geometrically similar pylon- mounted stores differing in diameter by a factor of about four and four pylons differing in height were tested. Pressure distributions on the airfoil were obtained for the clean airfoil configuration and 12 pylonstore combinations. The pressure distributions were integrated and the lift, drag, and pitching- moment coefficients for the airfoil are presented. Total pressure wake surveys and oil flow photographs were also obtained for the test, and typical data are presented.
