Creation and Non-Destructive Control of Electric Heating Elements of the Aircraft Icing Prevention System

Abstract

One of the priority directions of searching for new materials and testing methods in aviation is the development of conductive composition and manufacturing of heating elements (HE) for the electrothermal anti-icing system of aircraft and their nondestructive control. Using of polymer materials with nanotubes, as well as graphenebased heaters, have low weight, fast and uniform heating, and efficient energy consumption. Conducted research using a scanning electron microscope (SEM) to optimize the composition of carbon fillers (graphene and carbon nanotubes) in composite materials for creating electrically conductive anti-icing elements of aircraft structures. One of the most important instrumental methods of technical diagnostics of potentially dangerous objects is remote infrared (IR) thermal imaging diagnostics based on the registration of the temperature field. The principle of thermal diagnostics is based on the comparison of the thermal fields of the reference and the monitored object. Temperature anomalies are indicators of defects, and the value of temperature signals and their behavior over time makes it possible to give quantitative estimates of the object's parameters. Namely, with the help of thermal imagers, non-destructive thermal control is carried out not only of propeller screws. panels of rockets and airplanes, but can also be offered to assess the quality of HE. They detect defects. cracks, structural changes, water infiltration sites and ice jams.
