Description

Drone-mounted shell dropping module and drone having the same {Drone-mounted shell dropping module and drone having the same}

The present invention relates to a shell dropping module for mounting on a drone and a drone having the same. More specifically, it is mounted on a flying drone to stably drop shells at a set location while flying with shells such as mortar shells attached. It relates to a drone-mounted artillery drop module that can be mounted on a drone and a drone having the same.

Typically, conventional military drones have a dropping device that can drop artillery shells. This dropping device hangs one end of a shell and fixes it in a vertical direction, releases the fixation at a certain flight position, and drops the shell. Conventionally, airdrops are made by taking into account the weather conditions during flight, but in practice, if the shells are simply released from the vertical position and dropped, the terrain of the dropped shells will be distorted, and eventually they will not be dropped accurately at the expected drop location. There is a problem that I cannot do.

In addition, there is a problem of safety accidents occurring during flight as fixed shells move in an unstable fixed state due to air resistance during flight.

In addition, in the related art, when the shell is released from its fixed state and dropped using only gravity, there is a problem in that the dropping speed of the shell cannot be substantially controlled variably according to weather conditions.
