WebAbstract - Design and analysis of propellant grain configurations for determination of the grain geometry which is an important and critical step in the design of solid propellant … A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Arabs, Chinese, Persians, Mongols, and Indians as early as the 13th century. All rockets used some … See more A simple solid rocket motor consists of a casing, nozzle, grain (propellant charge), and igniter. The solid grain mass burns in a predictable fashion to produce exhaust gases, the flow of which is … See more Solid rocket fuel deflagrates from the surface of exposed propellant in the combustion chamber. In this fashion, the geometry of the propellant inside the rocket motor plays an important role in the overall motor performance. As the surface of the propellant … See more A convergent-divergent design accelerates the exhaust gas out of the nozzle to produce thrust. The nozzle must be constructed from a material that can withstand the heat of the combustion gas flow. Often, heat-resistant carbon-based materials are used, … See more The medieval Song dynasty Chinese invented a very primitive form of solid-propellant rocket.
