IMPACT OF HELICOPTER DESIGN ON RADIATION PATTERN OF ITS ATNENNAS

Abstract

This paper considers as the helicopter body affects directional characteristics of antennas. The article takes into account the effect of antenna position to achieve the best results in terms of antenna performance. It examines the possibility of measurements on scale models of aircraft, Mi-8 model in 1:20 scale. To obtain reliable results of measurement we are using depolarization panel. This article contains three measurements, two measurements with different positioning of measuring antenna and a separate measurement of the antenna as a standard of measurement. An interesting result is significant loss in specific settings of the measuring antenna. The results obtained to better understand the impact of the shape of a helicopter fuselage on transmission characteristics of antennas. Achievements of the thesis can be considered for future adjustment mounting of antennas and their better possible configuration in order to achieve higher performance.
