In addition to aerodynamic pressures, the wing of a flying boat is also subjected to combined hydrodynamic forces from the ski side (caused by landing and takeoff on the sea). In the asymmetric seating mode, the bending moment applied to the wing spars is one of the most important loading modes in the design of the wing spar structure. In the composite wing, the most critical part is the connection of the flange to the spar. In the finite element modeling of the real composite wing, which consists of a number of spars, ribs and other members, the connection of the flange to the web is done in a simple way without modeling the details of the connection.
In this research, the finite element analysis of the wing spars of a flying boat with cross section I with different geometries under different types of loading (according to the standard) for different functional modes is performed. then, based on the results of the numerical analysis, general and simple design rules and guidelines are presented regarding how to connect the flange to the web of these spars.
At the end, in order to validate the results of the finite element, an experimental sample has been built and tested, and the comparison of the results shows a very good match.
