Comparison of flight and analytical lateral accelerometer data of ROHINI sounding rockets

The lateral accelerations at different points of the rocket are computed by a 6-D trajectory program capable of simulating the effects of winds and misalignments. The results of actual wind, assumed values of thrust and fin misalignment and assumed values of linear and angular errors in placing the accelerometers are compared with the flight data obtained through telemetry. The analysis shows that the effect of linear and angular errors in placing the accelerometers is more severe than that of normal winds and other misalignments.
