A door assembly for a fuselage of an aerial vehicle is described, including a pair of complementary door pieces, and an actuation mechanism that includes a first transmission member. The first transmission member actuates either one or both door pieces for portions thereof to be in a sliding action with respect to the fuselage while maintaining close conformity thereto as either one or both of them are actuated to either meet or separate. Further disclosed are various embodiments of the door assembly, and a related aerial vehicle and system for delivering goods.

A lightning strike resistant structure of a flying object includes a lattice-shaped conductor 11 surrounding a flying object 100 with a distance not hindering flight, an attachment part 12 for the conductor 11 connected between the lattice-shaped conductor 11 and a part of the flying object 100, and a conducting wire 13 connected between the lattice-shaped conductor 11 and a ground point on the ground.

An aerial vehicle system for detecting magnetized objects comprises a propulsion system and sensor bar having magnetic field sensors at opposite ends to collect magnetic field data. In one example, the sensor bar extends at least one and a half times the propulsion system's length. The system further includes a positioning system, an altitude sensor, and an energy storage system. A processor executes flight instructions to navigate the aerial vehicle along a predefined path, collecting magnetic field and position data. A magnetic field information analyzer processes this data, generating expected magnetic signatures, comparing them to collected data, and predicting magnetized object locations. A user interface allows flight path customization and overlays detected objects onto a map of the surveyed area. The system can identify unexploded ordnance and landmines by comparing detected signals to predefined thresholds. The method includes controlling flight, collecting magnetic data, and analyzing signals to detect magnetized objects.

A work system which performs a work to a structure, and includes an aircraft, and a robot which performs the work to the structure. After the aircraft conveys the robot to the structure while holding the robot, the aircraft releases the robot after the aircraft lowers the robot onto the structure. The robot is released from the aircraft, and then performs the work to the structure.
