Evaluation of the Aerodynamic Characteristics of a 1/20-Scale A-10 Model at Mach Numbers from 0.30 to 0.75

Abstract

A 1/20-scale model of the A-10 aircraft was tested to determine the aerodynamic and control characteristics of the basic aircraft, evaluate the effect of external store configurations on the static stability and drag characteristics of the aircraft, and investigate the effects of Reynolds number, boundary-layer transition grit, and aerodynamic hysteresis on the data. Data were obtained at angles of attack from -4 to 20 deg and a sideslip angles from - 10 to 10 deg. The Mach number range was from 0.30 to 0.75, and the Reynolds number range was from 0.7 to 4.9 million per foot.
