Approved for public release; distribution is unlimited / The defense response against chemical and biological (Chem/bio) weapons has gained a renewed focus in light of the 11 Sept 2001 terrorist attack. A successful response to a Chem/bio attack would involve measuring and predicting the dispersion of a toxic cloud in the atmosphere. TheNPS Aeronautics and Astronautics Department is working together with the Meteorology Department on a technique to make toxic cloud measurements using an Unmanned Air Vehicle (UAV). In support of this mission, the UAV will require precise and accurate air data (airspeed, angle of attack ["alpha"], and sideslip angle ["beta"]) so that wind data extraction can be carried out from air and inertial data for use in plume dispersion modeling. The efforts in this thesis concentrate on the air data system to produce precise and accurate air data for the support of the Chem/bio response UAV flights. The primary concerns are the choice and design of the air data system; the calibration of the system using the flow fields from computer simulation; and the processing of air data. The air data extracted will be used for wind determination so that the movement of the Chem/bio dispersed agent in the atmosphere can be predicted. / Captain, Republic of Singapore Air Force
