Surface mesh movement for aerodynamic design of body-installation junction

A study was conducted to demonstrate a new method for surface mesh movement, which was used for performing aerodynamic shape design of body-installation junctions. The surface mesh points were moved directly on the surface, using a spring analogy based on geodesic distances on the surface mesh. The initial surface mesh was used to search for new junction points and move the mesh points to create geometric representations. Th new mesh points were projected onto the initial smooth surface by a surface recovery method. Some of the significant steps involved in formulating the new method, included modifying geometrical shapes of wings and fuselage, determining a new location of wing-fuselage junction nodes, and calculating geodesic distances from the initial to new junction nodes along the surface mesh. Another step involved in formulating the new method, included modifying the initial volume mesh according to the movement of surface points using a 3-D volume mesh modification method.
