The UAV structural elements' quick-release fastening system, which includes at least two tail booms coupling with a center wing section/fuselage of a UAV and a tail assembly by at least two quick-release coupling elements from the center wing's section side and at least two coupling elements from tail assembly's side, the UAV wiring elements. The docking chucks are used as the quick-release coupling elements. Coupling and fixing the tail booms with a tail assembly realized by the tail assembly docking chucks and a bayonet mount. Coupling and fixing the tail booms with a center wing section/fuselage of a UAV is realized by the center wing section docking chucks and the center wing section fixing pins or by the center wing section docking chucks and bayonet mount. The system is generally used in a UAV design with integral or dismountable tail assembly.

Systems and methods include UAVs that serve to assist carrier personnel by reducing the physical demands of the transportation and delivery process. A UAV generally includes a UAV chassis including an upper portion, a plurality of propulsion members configured to provide lift to the UAV chassis, and a parcel carrier configured for being selectively coupled to and removed from the UAV chassis. UAV support mechanisms are utilized to load and unload parcel carriers to the UAV chassis, and the UAV lands on and takes off from the UAV support mechanism to deliver parcels to a serviceable point. The UAV includes computing entities that interface with different systems and computing entities to send and receive various types of information.

A rail-based modular aircraft system may include a rail extending from a first end to a second end. The rail-based modular aircraft system may include a constant cross-sectional shape from the first end to the second end. The rail may also include a wing module configured to interface with the rail such that the wing module is individually movable along at least a portion of the rail and configured to be fixable at a fixed point along the rail. The rail-based modular aircraft system may also include a propulsion module configured to interface with the rail such that the propulsion module is individually movable along at least a portion of the rail and configured to be fixable at a fixed point along the rail. The propulsion module may be configured to provide forward motion to the modular aircraft system.
