AeroVironment [AVAV], Smiths Detection and the Army Edgewood Chemical Biological Center teamed to develop a chemical sensor that could fit into the nose cone of an unmanned aerial vehicle (UAV) that was successfully demonstrated during a flight test. For the test AV’s RQ-11B Raven UAV was fitted with a modified version of Smith’s Lightweight Chemical Detector, which is a commercial variant of the Joint Chemical Agent Detector the company makes for the Defense Department. The modification into a cylindrical form factor allows the Chemical Sensor Module to fit into the Raven’s nose cone. The sensor is capable of automatic detection, identification and quantification of dangerous chemical warfare agents. Algorithms developed by DoD allow the Raven to operate in a semi-autonomous mode analyzing the data collected by the CSM and determining chemical cloud size, direction and density in real-time. The flight test was done at the Army’s Dugway Proving Grounds in Utah, demonstrating detection and identification of a chemical and tracking of the vapor plume autonomously. Thousands of Ravens are deployed with the U.S. military and several allied military forces. Boeing [BA] previously has successfully demonstrated is ScanEagle UAV for tracking simulated biological plumes and collecting airborne agents under contract with the Defense Threat Reduction Agency (TR2, March 19, 2008).
