MAIN TRENDS IN DEVELOPMENT OF MODERN AIRPORTS

The article highlights the experience of design and construction with the expansion of existing airports, considers the factors that shape the development trends of modern international airports. Some general principles and methods of expansion of international airports are revealed. The formation of modern airports is influenced by many factors, primarily socio-economic and trends in air transport. In the last 20, 30 years, the largest percentage of the world's reconstruction is with the mandatory expansion of airports. Thus, the main issues of development of modern airports are the principles and methods of their expansion. Additional factors influencing the reconstruction of modern airports are issues of terrorist and virological security. If the issue of terrorist threats has influenced functional decisions for several decades, the virological threat is quite new and requires a comprehensive study and implementation of new measures of various kinds. Also, the purpose of the reconstruction of modern airports is to improve the level of comfort and safety, which are the main factors in the marketing struggle for air passengers and air cargo. The publication considers several typical modern examples of airport reconstruction, both in Europe and in the post-Soviet space - Kutaisi (Georgia), Marseille (France), Oslo (Norway), Amsterdam (Netherlands). The publication highlights that the expansion of the airport requires some mandatory stages. Namely, determining the appropriateness of the expansion and the main functional tasks for which this expansion should take place, determining the principles and techniques by which the expansion of the terminal will be most rational, determine whether the increase in passenger traffic requires runway expansion, determine how the increase in passenger traffic additional functions (parking, trade and food services, etc.). Of the above examples of expansion of modern airports, the most accurate is the method of expansion, which is a kind of symbiosis of building a new terminal with redistribution of functions between the new and old terminal, and with the simultaneous addition of necessary planning transitions and galleries.
