Description

A mobile-launched wireless spraying recovery mine-suppression rocket and its operation method

technical field

The invention relates to a mobile launchable wireless spray type recoverable mine elimination rocket and an operating method thereof, belonging to the technical field of artificial weather modification.

Background technique

Lightning disasters are listed as "one of the ten most serious natural disasters" by the United Nations. The earliest successful experiment of artificially triggering lightning was carried out by Newman on the Florida ocean in 1966. After that, the artificial triggering of lightning was successfully realized by launching and dragging thin metal wires to thunderstorm clouds. China, France, Japan and the United States have all carried out artificial lightning tests and comprehensive measurements. Since the 1990s, they have further developed and perfected the so-called "air trigger" lightning technology, so that when the thin metal wire is brought into the air by the rocket, Under the action of the electric field of the thunderstorm cloud, the connection between the upper end and the lower end of the nylon wire will respectively stimulate the upward and downward leaders, and they will transmit to the thunderstorm cloud and the ground in two directions under the action of the environmental electric field. However, the purpose is to conduct a quantitative study after the lightning current is introduced into the ground.

Although the lightning-guiding rocket dragged with metal copper wires can trigger lightning and indirectly weaken the electric field inside and outside the thunderstorm cloud, there are serious shortcomings in the use of lightning-guiding rockets for lightning elimination: ①Due to the towed traction wire, it can only be launched vertically, so the launch angle It is very small, requires a dedicated launch site, has poor maneuverability, and has a low probability of triggering lightning. ② There is a great potential safety hazard. If the lightning is not successful, the copper lead wire will cause great harm if it is lapped to a high-voltage wire or a pedestrian during the landing process.

Based on the above-mentioned shortage of wired rockets triggering lightning, it is imperative to develop a new type of wireless spray-type flash-elimination rocket.
