A design and manufacturing process for composite fittings (a part of a truss structure of aircraft) is discussed. Intersecting tubular rods are connected via ruled surfaces such as a hyperbolic paraboloid. A mathematical model of X-fitting surface is developed, and numerical simulation of the fitting is performed to optimize its geometry. Due to the thing that interface surface is ruled, reasonable composite application and, as a result, high weight efficiency of the structure may be achieved.
