Abstract: The article is devoted to the procedure of ice simulation onto antenna support bearing profiles in the climatic chamber of the DonNACEA. There was developed a test bench and mounting base to study real coatings of ice on angles of different cross-section at wind directions 450 and 900 to study icing factor symbol3.png2. To develop the test bench of ice coating imitation, the conditions were simulated in such a way that scale coefficients of wind velocity and direction, of drop diameter, of outdoor temperature and profile section which characterize the similarity conditions of the model and natural processes of deposition of cloud drops obtained by solving a mathematical problem were performed in the scale 1:1. So, to solve a targeted problem there was designed and created a climatic chamber in the DonNACEA. The procedure represented allows performing model ice-wind tests and then to determine carrying capacity, deformability, mechanical strength and antenna support natural frequency of oscillations and resonance under ice-wind effects with a specified coefficient symbol3.png2.

Keywords: antenna support, icing, wind, climatic chamber, angle, procedure, testing, ice-wind effects, coefficient symbol3.png2, test bench, test program, nozzles.
