A Ballistic Technique for Accurate Measurement of Total Impulse and Thrust of Rocket Motors with Short Burning Times,

Abstract

A method is described whereby a rocket motor impulse lasting a few milliseconds may be spread over a longer period to allow it to be recorded by conventional methods with an accuracy of plus/minus 0.2%. Instantaneous thrust is also recorded with an accuracy of plus/minus 2%. Most of the problems encountered with a ballistic pendulum are avoided and only the static calibration of a load cell is required before use. (Author)
