    Abstract

    This document describes the procedure for conducting proper ballistic flight experiments and analysis of free flight data generated in aeroballistic range facility. The need of proper excitation of the modalities of the model is stressed. The aerodynamic derivatives have been estimated from short length(approx 0.04 sec, and seven points)of free flight trajectory of scaled Agni pay load model using maximum likelihood method.The estimated derivatives are consistent with physics of flight and reference values.
