Specific Impulse Measurement Method of a Solid Propellant Engine

Abstract

 Characterization of solid, liquid, and hybrid rocket engines is often performed with computer modeling and ground testing. Specific thrust is one of the most important parameters describing the propellant at all, as it is used to distinguish between the types of propellant, especially in terms of the range of the propellant rocket engine. In general, the value of the specific impulse of the solid propellant ranges between 100-270 sec), and the higher this value is the more thrust of the mass of propellant is paid. Through the static test of the solid propellant engine, the thrust force is calculated and thus the total thrust is calculated, and from then the specific impulse is calculated after knowing the mass of the propellant.
