Calculation of the Interference Effects Between the Engine Wing and the Base Wing of a Civil and Military Transport Aircraft by the Vortex Lattice Method

摘要

For incompressible symmetric flow, calculations of the interference between engine and basis wing of the VFW-Fokker 614 civil-military transport aircraft model were performed. The following parameters were used: angle of attack 0, 3, and 5 deg for three different engine wings each with -10%, 10%, 30% or 50% overlap between engine and basic wing. The results of the linear and nonlinear calculations are discussed.
