Abstract

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.

Claims (7)

1. A lightning strike resistant structure of a flying object, comprising:

a lattice-shaped conductor surrounding the flying object with a distance not hindering flight;

a conducting wire connecting the lattice-shaped conductor to a ground point of a ground, wherein the conducting wire causes a lightning strike current received by the lattice-shaped conductor to flow to the ground; and

an insulating rod member connecting the lattice-shaped conductor to the flying object, wherein the lattice-shaped conductor is connected to only a single point of the flying object via the insulating rod member and prevents any portion of the lightning strike current from flowing into the flying object.

2. The lightning strike resistant structure according to claim 1 , wherein

The flying object is an unmanned aerial vehicle.

3. The lightning strike resistant structure according to claim 1 , wherein the conducting wire connects the lattice-shaped conductor to a lightning rod disposed on the ground.
