Abstract: Results of the parametrical experimental studies of the long-haul aircraft high-lift devices on small-scale half-model are presented. A maximum lift coefficient Cya max dependence on the Reynolds number was obtained for the tested model, which allows to estimate the value of the Cya max under full-scale conditions. The influence of high-lift devices parameters on the lift coefficient is shown.

Keywords: long-haul aircraft, high-lift devices, windtunnel, aerodynamic characteristics.
