The development of technology imposes new, higher requirements on those that exist. Encourages the creation of new materials. In order to reduce the weight of aircraft structures, for example, multi-layer structures that combine lightness, rigidity, and strength are used. For many areas of technology is necessary such that combine structural strength with high electrical, thermal, optical, and other properties. Regulating the structure of traditional materials is a promising way to improve quality. Thus, by means of directed crystallization of steels and alloys, cast parts are obtained, for example, gas turbine blades, consisting of crystals oriented relative to the main stresses in such a way that the edges of the grains are unobtrusive. Directional crystallization allows increasing plasticity and durability several times. The greatest environmental pollution occurs in the area of airports (airfields) during the landing and take-off of aircraft, as well as the warming up of their engines. When engines are running on take-off and landing, the maximum amount of carbon monoxide and hydrocarbon compounds enter the surrounding environment, and the maximum amount of nitrogen oxides enter the flight process. A jetliner that makes a transatlantic flight requires from 50 to 100 tons of this gas. On the territory of the airfield, engines are launched, taxiing, take-off, and landing of aircraft, during which harmful exhaust products of aviation engines, pre-launch (waiting location) and on the runway enter the atmosphere.
