Abstract:

The defense response against chemical and biological Chembio weapons has gained a renewed focus in light of the September 11, 2001 terrorist attack. A successful response to a Chembio attack would involve measuring and predicting the dispersion of a toxic cloud in the atmosphere. The Naval Postgraduate School 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 behind this thesis concentrate on developing an air data system that will produce precise and accurate air data in support of the UAV flights. The primary concerns are the choice and design of the air data system, the calibration of the system using 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 Chembio dispersed agent in the atmosphere can be predicted. 3 tables, 63 figures, 12 refs.
