DESCRIPTION OF A CONTROL SYSTEM FOR ROCKET-MOTOR MASS MEASUREMENT

Abstract

A technique for determining the mass of large rocket motors during burning, and an experimental system developed for use with the NOTS- designed three-component static-test stand at the Skytop facility, are described. The technique involves mounting the rocket motor on springs and continuously exciting the spring mass system natural frequency. The theoretical design of the control system is discussed and theoretical system-performance characteristics are compared with those of the experimental system. Results of an analog simulation study conducted in two degrees of freedom are included in the appendix. Analysis of data from an evaluation test involving the static firing of a large rocket motor, indicates that a 2% accuracy in mass measurement is attainable with the experimental system. Criteria for the design of an operational system that will produce an accuracy of 1% are presented.
