Resumen
The subject of study in the article is approaches to improving the system of protection of structural elements of a military transport helicopter from ice formation. The goal of the work is to develop proposals for improving the most energy-intensive system of the aviation equipment of a military transport helicopter, namely, an anti-icing system based on an analysis of as many of its components as possible. The following tasks are solved in the article: analysis of modern anti-icing systems (primarily those used in industrial plants and foreign helicopters), development of a backup system for heating the cockpit glass, development of a non-contact method of transferring electricity to the heating elements of the propeller blades, development of block diagram automatic control of the anti-icing system. The following methods are used: comparative analysis, methods of applied hydrodynamics and electromechanics. The following results were obtained: specific requirements for helicopter ice protection systems were formulated, a liquid cockpit glass washing system was proposed as a backup system for electric heating, a control system scheme for a 6-section anti-icing system using a combined ice formation warning device was introduced. Conclusions: the introduction of a fully automatic ice removal system as a part of the helicopter?s aviation equipment, which significantly relieves the crew, necessarily involves the use of an integrated sensor (group of meters). This will allow the system to respond not only to the appearance of a certain layer of ice on a sensitive surface, but also to environmental parameters at which such a dangerous phenomenon as icing of helicopter structural elements may occur. Modernization of the anti-ice formation system on the elements of the helicopter structure will be effective only with a comprehensive approach to the improvement of all its components together with the development of duplicate ice removal systems.
