Abstract
The aerospace industry is a sector with primary demand for mastering cutting-edge technologies and innovations. It has the potential to pull other sectors to previously unattainable levels. Its current transformations and emerging new vectors are of key importance for a wide range of areas in the economy and society. Currently, companies in this sector are faced with the challenges of mastering Industry 4.0 technologies. The article examines the main trends and technological achievements in the global aerospace industry. Based on the presented picture, the authors propose an adapted model for assessing the technological maturity of the aerospace sector, tested on the example of Brazil. Pilot testing of the companies included in it, using this model, showed that for most of the aspects considered, the level of technological readiness does not exceed the second (with a scale of five levels), and this is despite the fact that the products of the Brazilian aerospace sector are in high demand in many countries, including developed ones. The presented model can be adapted to assess the technological maturity of other sectors of the economy.
