In activity the necessity of mechanization and automation of processes of clearing of outside surfaces of aircraft is justified. The analysis physico-chemical interaction of surfaces with an environment has shown that the contamination of surfaces is process, not alienated from maintenance. The extended classification of contamination of surfaces is offered. The methods of clearing are considered and the area of their application is indicated. The statistical data on a topography of surfaces aircraft of production country of CIS are adduced. It is shown that the known devices are not adapted to the mechanized clearing of outside surfaces of aircraft because of an imperfection of their brushes. Because of experimental data obtained by the author, the theoretical researches are confirmed and the analytical relations of parameters of a spot of a contact to geometry of contacting skew fields, pressure inside the pneumatic chamber, their mutual position, elastic properties of a material of the jacket and chamber, compression and other factors are obtained. The comparison of the obtained data with the data of other authors has shown their satisfactory coincidence. The outcomes of researches have confirmed high adaptability of a design of brushes developed by the author. On the developed mathematical models the techniques of calculation are recommended selection basic elements of adaptive brushes allowed pressure on a cleared surface and modes of their activity. Because of conducted researches the new concept of a design of brushes is developed and the packet of adaptive brushes for the mechanized clearing of surfaces is offeredSummary in Latvian, EnglishAvailable from Latvian Academic Library / LAL - Latvian Academic LibrarySIGLELVLatvi
