Optimization of a complex of technological equipment for aircraft processing

Abstract

When icing, aerodynamic surfaces of the aircraft, negative changes in the impact of the air flow on them occur, which leads to a noticeable drop in wing lift, a decrease in the efficiency of the rudders, a decrease in the aircraft and loss of control. In order to optimize the complex of technological equipment for anti-icing treatment of the aircraft, the necessary studies of materials and methods of anti-icing treatment of aircraft were carried out, based on the KNO-AERO-MA complex, designed for processing (washing, anti-icing protection) of the outer surfaces of aircraft, due to the existing pumping equipment in the system of collecting and returning the spent solution. The essence of the filtering technology is to clean solutions from harmful impurities through a special porous medium, the so-called filter. The created simplified model of a high-speed pressure vertical filter made it possible to study one or more filter links of the filter column. According to the research results, in order to optimize the technological equipment complex during aircraft anti-icing treatment, in the system of collecting and returning spent solutions for repeated anti-icing treatment of aircraft, it is recommended to use a highspeed pressure vertical granular filter. The introduction of such a system will allow servicing several aircraft simultaneously, significantly reduce the cost price and improve the environmental friendliness of this technological process.
