MEASUREMENT OF WIND SHEAR.
Abstract
Several mathematical approaches were examined in an attempt to extract the effects of probe tilt from recorded data. The approaches consisted of examining the accelerometer output and relating the measured response to approximated equations of motion, and of using aspect sensor data to determine if tilt effects upon the measurement of the earth's magnetic field could be found. Both were found to be impractical and incapable of generating the desired results. The latter technique, however, provided the determination of bounds upon probe tilt and indicated that previously measured data obtained tilt error no greater than five degrees during the drop. A calibration study was conducted to investigate the feasibility of using simulated wind shears to evaluate the probe measuring system. The study indicated the many problem areas within the scope of calibration definition and that the fabrication of a test facility to conduct such testing would be an extensive undertaking. (Author)
