Abstract

Provided is a rocket for artificial rainfall using an ejection hygroscopic flare, the rocket including: a rocket body configured to descend with a parachute after flight by thrust, and having a hygroscopic flare discharge outlet; a communication module installed in the rocket body, and configured to transmit and receive a launch command and an ejection command with a ground station; an ejection hygroscopic flare installed in the rocket body and filled with cloud seeds and a burning material therein; and a hygroscopic flare ejection device configured to separate and eject the ejection hygroscopic flare from an inside of the rocket body to an outside thereof.

First claim

What is claimed is:

1. A rocket for artificial rainfall using an ejection hygroscopic flare, the rocket comprising:
a rocket body configured to descend with a parachute after flight by thrust, and having a hygroscopic flare discharge outlet;
a communication module installed in the rocket body, and configured to transmit and receive a launch command and an ejection command with a ground station;
an ejection hygroscopic flare installed in the rocket body and filled with cloud seeds and a burning material therein; and
a hygroscopic flare ejection device configured to separate and eject the ejection hygroscopic flare from an inside of the rocket body to an outside thereof.

2. The rocket of claim 1 , wherein the ejection hygroscopic flare comprises:
a cylindrical hygroscopic flare body with an open end; and
a cover coupled to the open end of the hygroscopic flare body,
wherein a plurality of discharge holes are formed along an outer circumference of the hygroscopic flare body.

3. The rocket of claim 2 , wherein the hygroscopic flare body comprises a main chamber and an extension chamber connected to the main chamber,
wherein the main chamber comprises a bottom portion, a cylindrical outer portion connected to the bottom portion, and a coupling flange extended from an end of the outer portion and connected and coupled to the extension chamber; and
wherein the extension chamber has a cylindrical structure, with opposite ends from each of which a coupling flange is extended.
