Aviation industry of XXI century: development and necessity or serious threats for natural ecosystems

Abstract

At this stage scientific and technological progress, which reaches unprecedented levels is characterized by the continuous creation of new and improved existing technologies and means of production. In turn the aviation industry is the realization of new achievements and achievements in the practical aspect of application. There are the developments of new equipment, both on-board and on-board; creation of powerful engines; updating fleet of aircraft, as well as designing new types. But along with such positive achievements at the first glance, aviation transport remains a large source of harmful factors for the environment, the first of which is usually in the vicinity of large cities, and the latter, in turn, within large citiesTherefore, the current situation leads to the necessary, development and implementation of a comprehensive environmental safety program in aviation transport. Most recently, experts and specialists in the field of the aviation industry have concluded that the using of passenger flight services as well as freight aircraft services have been much more efficient from an economic point of view than the using of automobile transport.So, in general, a passanger jet needs 100 times more fuel for a flight than an automobile. But if you talk about fuel consumption for a trip to a particular distance, in this case, that the needs of the aircraft will be almost 2 times less than for the automobile transport. Let's consider this situation on a concrete example. How will the amount of necessary fuel for the Boeing 747 passenger aircraft and the Honda Civic passenger car differ, in overcoming the distance from Chicago to London? Fig. 1. Airplane and automobile movement relative to the same distance with different costs of high-quality fuel Chicago London Passenger jet Automobile 200 liters = 53 gallons of fuel 532liters = 136 gallons оf fuel

Environmentally sustainable airport development: Ukrainian case of decarbonization

“…New technologies are also being introduced to reduce CO 2 emissions using new aircraft engines, hybrid systems and full-electric propulsion systems. For example, American Society for Testing and Materials D-7566 fuel, which has passed the standard specification for aerodynamic turbine fuel, German promising four-seater H2FlyHY4 with hydrogen fuel cells, which was recognized successfully during the flight (Novakovska et al , 2019). Also, the French company Laboratoire Ocean Vital, engaged in research in renewable energy sources, intends to conduct flight tests of a hybrid biplane.…”

“…Composition of chemical parameters as a result of the processing of oil and motor oils, transmission other spoiled or used (%; Novakovska et al , 2019)…”

“…Planes move from one airport to another during the flight, and the atmosphere is polluted globally, meaning significant pollution Novakovska et al, 2019) occurs in airport areas and on flight paths. Moreover, if on the flight tracks, the danger from this pollution is small (flights of aircraft at high altitude and high speed), causing the dispersion of combustion products in the upper atmosphere and over large areas, which reduces the degree of their impact.…”
