Anomalous Behavior of a Solid Rocket Motor Nozzle Insert During Static Firing Test

Journal of Aerospace Technology and Management, 2016
This paper presents the study and development of a firing test used to evaluate the behavior of a solid rocket motor. The motivation for the development of a subscale solid rocket motor with end burning propellant grain geometry arose from the need to ...
