Abstract: This lightning discharge induction system includes a flying object (1) flying in the air, a discharge electrode (11) provided to the flying object, a ground electrode (3) provided on the ground, an electric wire (2) connecting the discharge electrode (11) and the ground electrode (11), and a voltage control device (4) controlling a voltage generated in the discharge electrode (11). The voltage control device (4) includes a pulse power supply (41) for generating a pulse voltage, and a trigger switch (S1).

Abstract: A lightning induction system includes a plurality of flight vehicles 3 that fly between a lightning originating point 1 in the sky where lightning is generated and a ground surface 2. The flight vehicles 3 each include: a flight unit 10 that generates lift force and propulsion force; a conductor cable 20 that is engaged with the flight unit 10, extends downward, and has a predetermined length; and a weight unit 30 connected to the lower end of the conductor cable 20. The flight unit 10 is disposed in a Faraday cage 11. The Faraday cage 11 has a sphere shape, and the flight unit 10 is fixed by a support pillar 12 extending downward from the inner side of the top of the sphere.

Abstract: A lightning stroke 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.
