Determining Aerodynamic Loads Affecting an Aircraft Wing During Parametric Modelling Taking the Main Airliner Components into Account

The investigation used parametric modelling to analyse the effects that the main airliner components have on the accuracy of determining aerodynamic loads affecting the wing. We considered configuration options in terms of both the whole airliner and a separate wing featuring a classic pylon-mounted engine underneath. We studied the effects that the following factors have on the accuracy of determining wing parameters: a diffuser, the bypass ratio of the engine, and finally the computational region size and the finite volume mesh density over the wing surface. We used the CFX tool from the ANSYS software package to perform calculations for the cruise flight mode of a swept-back medium-range airliner wing featuring a straight section and asymmetric aerofoil. We determined aerodynamic loads affecting the wing, its temperature due to aerodynamic heating and the flow pattern around it. We analysed preparation and computation times for the options under consideration. We determined reasonable input data parameters for the initial stages of wing design. A future methodology of polymer composite wing design based on parametric modelling will take these results into account and make use of them
