Apparatus for assisting formation flight of unmanned aerial vehicle

1. An apparatus for assisting formation flight comprising:

a formation maintaining member for maintaining formation of a plurality of unmanned aerial vehicles in flight and having connection points formed at points corresponding to positions of each unmanned aerial vehicle on the formation;

a plurality of fastening members, in which one end is connected to the connection points of the formation maintaining member and the other end is fastened to the unmanned aerial vehicle to connect the formation maintaining member and the plurality of unmanned aerial vehicles, wherein a movement permitting member for permitting a posture change of the unmanned aerial vehicle within a predetermined range is formed on the other end of the plurality of fastening members; and

a goods loading unit having a plurality of sidewalls formed between adjacent fastening members, and a seating surface formed in a space surrounded by edges of the formation maintaining member,

wherein the formation maintaining member has edge lines connecting the connection points and inner hollow surrounded by the edge lines,

wherein the formation maintaining member is not an article carried by unmanned aerial vehicles and is fixedly connected to the fastening members, and

wherein the goods seated in the goods loading unit are delivered using the plurality of unmanned aerial vehicles maintaining the formation.

2. The apparatus of claim 1 , wherein the fastening member extends upward from the connection point, and is fastened to the unmanned aerial vehicle located above the formation maintaining member.

3. The apparatus of claim 1 , wherein at least one of the sidewall and the seating surface is a net.

4. The apparatus of claim 1 , wherein the formation maintaining member has a shape of a regular polygonal, and the connection point is formed at each vertex of the regular polygon.

5. The apparatus of claim 1 , wherein the movement permitting member is a ball joint,

wherein the unmanned aerial vehicle and the fastening member are fastened by coupling using the ball joint.

6. The apparatus of claim 1 , wherein the movement permitting member is a ring,

wherein the unmanned aerial vehicle and the fastening member are fastened by coupling using the ring.

7. The apparatus of claim 1 , wherein the movement permitting member is an elastic member having a predetermined elastic force,

wherein the unmanned aerial vehicle and the fastening member are fastened by coupling using the elastic member.
