DISMOUNTABLE RESILIENT-LIKE AERODYNAMIC MODEL AND METHOD OF ITS MANUFACTURING Russian patent published in 2013 - IPC G01M9/08 

FIELD: measurement equipment.

SUBSTANCE: model comprises a power core and a cover, representing when assembled a single dismountable structure of a closed aerodynamic shape. The cover is made from a single unit of a low-modular material, such as foam plastic of alternating thickness along swing and chord of the bearing surface, divided into sections. Thicknesses of sections gradually decrease in direction from the local sites of contact of the sections with the model core towards transition zones, at the same time the angles of section face bevel make not more than 45-50°. Local sites are located in the central part of each section, and transition zones between sections are formed as a result of reduction of thickness of the single material block. The proposed method for manufacturing of the aerodynamic model includes milling of the core and the cover in CNC machines and also iteration finishing of stiffness characteristics of the assembled model. The cover is made by shaping or method of quick prototyping from a single block of a low-modular material. On its inner surface they create sections with local sites of contact with the core with slanted surfaces of section faces and transition zones of the sections. From outside and inside the cover is reinforced with cloth of unidirectional composite, and its transition zones are reinforced additionally.

EFFECT: simplified design of an aerodynamic model, simplified method of its manufacturing.
