Abstract

The BLWF code [1] was developed by researchers at the Central Aerohydrodynamic Institute (TsAGI). The BLWF code has been developed for preliminary aerodynamic analysis of transonic transport aircraft configurations. It can be used for rapid computations of viscous transonic flow over wing/body/nacelle/ tail configurations. Numerical simulations of the flow past the DLR-F6 wing-body configuration have been performed to evaluate the accuracy and efficiency of this code, when used for preliminary aerodynamic analysis of transonic transport configurations. A brief description of computational methods is given in Section 1. The numerical results and discussion are given in Section 2. The computational results for a prescribed Mach number (Ma=0.75) and prescribed design lift coefficient (CL=0.5) are compared with the available experimental data. The effect of Mach number on the aerodynamic performance is investigated by computations at Mach numbers from 0.2 to 0.9, with fixed Reynolds number and varying angles of attack. According to the evalution results, the BLWF code is well suited for the preliminary aerodynamic analysis of transonic transport aircraft configurations.
