FIELD: aviation.
SUBSTANCE: pattern is formed from the basic elements, composing the regular sections area, and the additional structural elements patterns, such as the aerodynamic fairing, air intake device and aerodynamic surfaces. The basic elements are made from the round tubes, having the variable diameter along the length, framing attached to them, the outer contour of which repeats the section shape of the master cross-section and the skin. The basic elements have such lengths and are composed in such a way, that the pattern suspension elements are located on the joints between the basic elements.
EFFECT: increasing of the overall mass characteristics and the simulated product external shape reproduction accuracy, provision of the manufacturability, strength and stiffness of the pattern.
