Original abstract

Unmanned aerial vehicles (UAVs), commonly referred to as drones, have become an essential component of modern aerospace systems due to their fast expansion across civil, commercial and military applications. Advances in lightweight materials, miniaturized electronics, navigation systems and manufacturing technologies have enabled the development of increasingly capable platforms ranging from small multirotor drones to high-altitude long- endurance aircrafts. This paper reviews the current status of the global drone sector by examining market evolution, industrial development and the principal regulatory frameworks governing UAV operations. A technical classification of drone configurations is presented, including fixed-wing, rotary-wing, hybrid VTOL and mission-oriented categories, highlighting their operational characteristics and engineering trade-offs. Representative civil and military platforms are comparatively analyzed in terms of range, payload, endurance, cost and mission capability in order to illustrate current technological trends. Attention is also given to structural materials and manufacturing technologies employed in modern UAV design (composite materials, lightweight alloys, additive manufacturing and modular construction concepts). The analysis shows that progress in materials engineering and airframe design, together with the diversification of operational requirements, is driving the development of increasingly efficient, specialized and adaptable unmanned aircraft. These trends confirm the importance of UAV technologies within the evolving aerospace industry.
