METHOD AND TOOL FOR SIMULATING THE AERODYNAMIC BEHAVIOR OF AN AIRCRAFT IN FLIGHT IN THE NEIGHBORHOOD

摘要

The invention relates to a method for computer simulation of the aerodynamic behavior of an aircraft (10) in flight in the vicinity of the ground. This method makes it possible to identify the effect of slope with respect to the ground effect. For this, a uniform boundary condition is imposed on a plan (21) modeling the ground including a predetermined velocity (Up) having a non-zero tangent component and a non-zero normal component; and a discrete numerical model of the Navier-Stokes equations is solved by computer, on a volume mesh, with said boundary condition imposed on said plane (21), so as to obtain the numerical solution of a fluid flow inside. a computational domain defined by said mesh.
