Abstract

In Aerospace Engineering, the main purpose of multifunctional coatings is thermal protection, protection against ionizing, electromagnetic and radio emission, reflection of laser influence, aimed at influencing the control system, electrical equipment and product devices. The secondary functions of multifunctional coating in rocket technology include increasing the strength and stiffness of individual external parts of the product, as well as protection against corrosion and erosion. During operation, aircraft, in addition to force influences, are continuously exposed to an extensive complex of external physical influences of a heterogeneous type: ionizing and radio emissions, large differences in thermal disturbances, harmful effects of electrodynamic and gravitational fields, geomagnetic and ionospheric factors. Therefore, the creation of an external multifunctional coating for the protection of rocket and space objects, which has a huge range of possibilities for reflection and absorption from external negative factors, is an urgent task in modern aerospace engineering. This paper presents an analysis of multifunctional coatings for rocket and space technology with various types of fillers, namely commonly used metals, rare-earth elements and their oxides, microglass spheres and carbon microstructures. The paper also presents an analysis of the composition of filler compositions of modern aerospace protective coatings for multifunctional purposes, analyzes foreign effective technical solutions for the external protection of aircraft. The results of the study will be useful in the development of new compositions of external protection of aircraft from external negative factors.
