Abstract
The measurement of thrust misalignment in rocket motors is described. The dynamics of the thrust stand installation are analyzed using load identification method. The variables influencing the system errors are identified and their influence quantified. The direction of the thrust vector of rocket motor can be resolved over 0.25 ms interval to within 0.7 mrad. The angle of the overall impulse vector can be measured with precision of better than 0.35 mrad.
