Wind Tunnel Investigation of the Pressure Distribution on a Two-Dimensional Airfoil with Pylon-Mounted Stroes at Mach Numbers from 0.7 to 0.95

摘要

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 pylon/store 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. (Author)
