Special Aircraft

Authors: Relly Victoria V. Petrescu and Florian Ion T. Petrescu Abstract: In this paper, the authors want to present a few more distinct aircraft from a constructive and functional point of view. Their role has often been determined by the need to achieve or fulfill certain more or less strategic objectives. Such ships will also be built in the future more and more often in order to be able to respond to all new flight requirements and to meet, under optimal conditions, the new and increasingly demanding requirements.

These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would not be able to take off or land.
