Description

Canister drop system using a hot air balloon and its operation method

An embodiment of the present invention is a canister dropping system using a hot air balloon and an operating method thereof, in particular, a canister dropping system using a hot air balloon that automatically drops the canister when the canister is mounted on the hot air balloon and reaches the target altitude and target position after the canister is mounted on the hot air balloon. and its operating method.

In general, missile launching methods are largely classified into hot launching and cold launching.

Hot launching is a method in which the missile exits the launch pad (launch tube) using its own rocket, and cold launch is a method in which a device is included in the launch pad (launch tube) to push the missile outward using compressed air, gunpowder, or cartridges. .

In the case of hot launch, the structure is simple, but it is implemented in a launch pad method in which flame treatment generated from a missile is essential and a canister method in which flame treatment is not required. It means a box containing a canister missile, and it is characterized by not requiring separate flame treatment. A missile launch system using a canister can launch a guided missile by disconnecting a connector to which a missile is connected within the canister and driving the missile.

In a conventional missile launch system using a canister, a method of dropping the canister after moving the canister to a target point using an unmanned aerial vehicle (eg, a drone) is used. However, when an unmanned aerial vehicle equipped with a canister takes off or falls, a problem arises in that the aircraft enters an unstable state due to a rapid weight change. This had the problem of causing danger to the aircraft. In addition, it has been difficult to implement a method of securing the canister within the vehicle.

The emission signal generation unit 116 may generate an emission signal after a predetermined time from the time point at which the target speed is entered (S70). For example, when the target speed is maintained for a predetermined period of time, the emission signal generation unit 116 may determine that the vehicle is in a stable state and generate an emission signal to emit the aircraft to the outside, and transmits the signal to the emission unit 117 .

The emission unit 117 may emit the vehicle according to the emission signal (S80). For example, by separating at least a portion of the case body 111, the ejection unit 117 may export an aircraft located inside to the outside.
