Abstract. This paper describes design technique of solid fuel rocket motor testing system for its thrust measuring capabilities. The design process consists of 2 parts. In first part the mathematic modelling technique will be described for the mechanical section, in second – electrical. This will help to explain versatility and capabilities for coupling of the parametric design process for measurement systems design using software supported modelling tools. In order to determine the potential utility load, module design and the stability of the system in next chapter model of the system is compared with actual measurement system prototype during experimental testing and evaluation. The error between modelled and real systems is measured and discussed. The final experiment is discussed where rocket motor was tested. Modelled thrust characteristics was compared with measured data for the final discussion and conclusions.

Keywords: rocket motor, thrust, measuring system, modelling, test stand.
