Abstract
  In this study, the simulation of internal ballistics and the exhaust flow of a solid propellant engine have been investigated. The flow field considered in this problem including the cylindrical grain and the solid wall of the engine and the flow at the nozzle outlet have been studied. The governing ...  Read More

Ahmad Mollaei; Yahya Ebrahim abadi; Navvab Fathi; Mohammad Javad Sotoodeh

Volume 4, Issue 1 , June 2020, , Pages 1-6

Abstract
  Igniters are main sections of motor that initiate the ignition of propellant grain. Large motors usually use pyrogen composite igniters. Pyrogen igniters have similar formulation with solid composite propellants, but their burning rate is relatively high. In this research, a composite igniter, based ...  Read More

Technologies and New Methods for Determining the Burning Rate of Solid Propellants

Mohammad Ali Dehnavi; Reza Emami

Volume 3, Issue 1 , June 2019, , Pages 57-67

Abstract
  The burning rate plays animportant role in determining the performanceandballistic behavior of solid rocket propellant. In this paper, the effect of various factorson burning rate, such as combustion chamber pressure, poropellant grain initial temperature, fuel/oxidizer ratio, composition of the components ...  Read More
