An Investigation of the Aerodynamic Characteristics of the AGARD Model B for Mach Numbers from 0.2 to 1.0

Abstract

A test was conducted to determine the aerodynamic characteristics of the AGARD Model B calibration model at Mach numbers from 0.2 to 1.0 for angles of attack from -4 to +24 deg. The tunnel blockage of the model at zero angle of attack was 0.15 percent. The data showed no evidence of tunnel interference and are considered to be interference free. The data agreed with other published data obtained at Mach numbers above 0.7. The curves of lift coefficient and pitching moment were found to be nonlinear near zero lift at Mach numbers below 1.0. Therefore, the lift curve slope and the neutral-point location should be used with caution when comparing data.
