{Apparatus for Airdropping Cargo Bags}

The present invention relates to an apparatus for aerating a large amount of cargo. More particularly, the present invention relates to an aerial dropper capable of simultaneously dropping a plurality of parachute assemblies accommodating cargoes through an aircraft to supply a plurality of articles to a target area.

The contents described in this section merely provide background information on the embodiment of the present invention and do not constitute the prior art.

Everywhere in the world, big and small battles are constant, and natural disasters such as climate change are causing many people around the world to lose their lives. War or disaster In rescue of human life in a disaster area, it is necessary to perform preliminary supply of drinking water, medicines and other relief supplies in order to maintain life so that the victim or the injured person does not die before rescue.

Relief material for accessible disaster areas can be quickly distributed in large quantities using land routes. However, in mountainous or raid areas, the use of land routes is limited. Therefore, it is necessary to supply relief supplies using routes other than land routes.

In the case where land routes are not available, the supply of relief goods is often carried out by air dropping the material through aircraft. For example, in the case of the US military, various cargo tactics such as LCADS (Low Cost Aerial Delivery System), TRIADS (Tri-wall Aerial Delivery System) and FDS (Free Drop System) To perform the supply mission to the target area.

On the other hand, the ROK Armed Forces are also studying techniques for airborne relief supplies for humanitarian aid to combat attendants or civilians in times of war and other disasters. As part of these efforts, we are continuing to conduct simulated cargo dropping training for the target area by dropping the Standard Airdrop Training Bundle (SATB) through aircraft.

However, the dropping method of SATB is only possible with a single drop, so the amount of cargo that can be dropped when the aircraft is flying once is insufficient. Therefore, it is necessary to develop an aerial dropping device that can supply a large amount of relief goods to the target area.

Disclosure of Invention Technical Problem [8] To solve the above problems, it is an object of the present invention to provide an aerial dropper capable of dropping a large amount of relief materials at a time in a target area at low cost and controlling a drop rate at low or high speed according to operational purposes .
