For the first time, this paper addresses the need to automate the maintenance of the quality control and control system at all stages and stages of the life cycle - anti-conduct fluid (POJ) for ground-based anti-de-dealing treatment (POO) of an aircraft. The possibility of evolution of the quality control of the object of ground de-icing physical and chemical treatment of the surface of the aircraft - de-icing liquids, in “Management of quality - de-icing liquid as an object to ensure the safe take-off of the aircraft” is considered. The definition was introduced: “The quality of de-icing liquid.” To integrate into the system “Management of the quality of de-icing fluid” - on the basis of knowledge bases about THE POJ introduced as a functional concept “The quality of de-icing liquid at the POO stage”. In order to introduce information software support for the POO process using databases and control systems, the concept of “Regeloscopic Ground De-Icing Protection Program of the Armed Forces” has been introduced, which will allow and move to an effective method of improving the quality of the service - integrated automation of the POO.
The article describes a technique that allows to form a planned projection of the aircraft using the minimum number of iterations (refinements based on aerodynamic and weight calculations results). The elements of the technique are described via example of the development (synthesis) of the layout scheme of a front-line aircraft with two engines and internal cargo compartments, performed according to the normal balancing scheme. Synthesis is carried out on the basis of certain predesign parameters, limitations, as well as solutions set by the designer, based on the analysis of parametric ratios and statistical dependencies.
The article describes a way to increase the efficiency of an abrasive tool by its impregnation in an aqueous solution of chromium diiodide. The device scheme for impregnating the instrument is proposed. Research results of durability of tools impregnated with chromium diiodide and structural condition of material of a surface layer of details after processing are resulted. Within of the researches presented in the article the grinding processing a shafts made from various iron-carbon steels with prepared abrasive tools was conducted. As a result of the machining the scattering fields of the batch sizes of the parts within the grinding wheel resistance were determined. This data for processing with standard grinding wheels and impregnated by chromium diiodide were done. Using data from controlled grinding of workpieces, approximate values of the KΔ coefficient were determined depending on the diameter of the workpiece surface, the required size accuracy of part and the method application of the surfactants. It is shown that regardless of the material being processed, the use of a grinding wheel impregnated with chromium diiodide leads to a reduction in the specific value of the accumulated deformation energy Espec. Taking into account these results it is possible to predict up to twofold reduction of the cost of machining with the abrasive tool of grinding parts, which will reduce the cost of their manufacture by 20-25%. The developed process of impregnating grinding wheels with chromium diiodide can be used without large economic costs in many machine-building company also during repair works.
