The 3D Numerical Analysis on the Predictions of Flight Stability at Take-off and Landing (Crosswind 60°)

Abstract

The aim of this paper is to research the change in the turbulent flow and the AOA occurred by 60°crosswind to the direction of runway through the three-dimensional numerical analysis and to predict the take-off and landing flight stability. As a result, the maximum amplitude of AOA variation on runway reached 4.88°within 7 second because of the wake formed by the constructions in the vicinity of the airport, and the overall effects appeared as an irregular aperiodic forms. Additionally, it was observed that the layout and shape of the buildings effected on the strength of turbulence directly, and the rapid flow generated between the buildings changed into stronger wake and eventually expected that the flow raises serious take-off and landing flight instability.
