Maintaining airport surfaces in good condition and in a good state of cleanliness throughout the year is of extreme importance to ensure the safety of flight operations by aircraft. The use of various equipment is practicable in order to clean regularly all paved surfaces. Components of brushes and plows during operation wear out and must be replaced periodically. New elements should be of adequate quality. Examples of airport cleaners and exchangeable cleaning elements are presented. Some requirements have also been given on the brushes’ bristles. To confirm the need to control the purchased cleaning elements, the condition of worn components was checked. The results of laboratory tests of new and used brushes bristles are presented. The tests included microscopic observations, microstructure assessment, tensile strength testing, and microhardness testing. Defects in fixing the bundles of polymer brush bristles during airport exploitation were found. Research on steel wires showed a partial loss of the zinc coating during the brush operation (potential corrosion), lowering the tensile strength and increase the hardness of the wires, which could lead to wires crack and break. The article confirmed the need to control of brushes and plows parameters to ensure their proper quality. Their selected parameters should be controlled during purchase and operation on airfields belonging to the Polish Armed Forces. The impact of deicing agents on the elements mentioned above should also be considered. |
