This study examined the potential of drones in response to chemical agent terrorism situations by conducting a step-by-step process that included technical foundations, application cases, and experimental verification.
First, an analysis of the drone's core technologies and applicable sensor systems confirmed that a sufficient technological foundation exists for detecting and analyzing contaminants while ensuring flight stability. Barometers, accelerometers, position sensors, and laser detection equipment can contribute to identifying aerial contamination spread paths, and when combined with real-time data transmission technology, can significantly accelerate on-site response times.
Following this, a comparative review of drone applications in the agricultural, environmental, disaster, and military sectors revealed that the structure and performance of agricultural pesticide drones, in particular, can be applied to blocking and decontaminating the spread of liquid and solid chemical agents. Considering the long development time required for military-specific equipment, this suggests that the conversion and utilization of civilian technologies is an effective way to strengthen initial response capabilities. However, it should be noted that complete neutralization and removal of chemical agents has clear limitations depending on the agent's properties and on-site circumstances, and ultimately, comprehensive ground-based decontamination efforts utilizing specialized personnel and equipment are essential.
In an experimental verification, a simulated North Korean waste balloon attack was simulated and the performance of the AGRAS T 40 and T 10 agricultural drones were compared. While the T 40 exhibited high spraying efficiency, the gaseous chemical agent presented a risk of contamination spread due to strong downdrafts, which could be a critical limitation in actual chemical agent control situations. In contrast, the T 10 maintained a certain level of decontamination coverage despite relatively low downdrafts, demonstrating performance more suitable for suppressing the initial spread of chemical agents.
These results suggest that selectively operating small and medium-sized drones according to the situation can enhance response effectiveness. Furthermore, integrating commercially available aircraft and technologies into a joint military-civilian response system can lay the foundation for establishing a Korean-style chemical agent quarantine system. However, this study has limitations in that it used a coffee solution as a substitute, as actual chemicals could not be directly utilized. Further verification of its performance is necessary through collaboration with military research institutions.
In conclusion, drones are highly effective tools for information gathering and initial response in the event of a chemical agent incident, including detection, surveillance, sampling, and initial identification of contamination points. Furthermore, they can play a supplementary role in suppressing the initial spread of disinfectants by spraying them in inaccessible areas. This study demonstrated the value of drones as a valuable "tool" in ensuring the safety and enhancing the efficiency of chemical agent countermeasure personnel in this complex decontamination process. This research can serve as foundational data for establishing institutional frameworks and operational guidelines.
