US Army Tests Drones That Sniff Out Poisonous Substances

Specialists of the US Army Chemistry and Biological Center, dealing with the protection of military personnel from weapons of mass destruction, tested Deep Purple unmanned aerial vehicles, the main task of which is to detect chemical agents and biological weapons.

From 15 to 26 August, clouds simulating chemical and biological weapons were released during the annual US Army S / K Challenge exercise. To avoid windy weather, all major events were held from 11 pm to 5 pm.

The quadcopters were equipped with TACBIO combined sensors that respond to chemical and bacteriological weapons. They were packed in thermos-shaped containers that were secured to the bottom of the drones.

The drone bodies are made of electronic boards instead of carbon fiber, as in most quadcopters. The team keeps in touch with them in real time at a distance of more than 3 km. The received data goes to the central information exchange system.

The information includes information about the location of the dangerous cloud and the direction of its movement from stationary ground sensors, which are then identified and transmitted to drones via communication channels, thereby forming an overall picture.
